Executive summaryThe aim of this report is to identify a hierarchy of sediment cells to assist planning, management, engineering, science and governance of the Vlamingh coast.
Sediment cells are spatially discrete areas of the coast within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange, often described using sediment budgets. They include areas of sediment supply (sources), sediment loss (sinks), and the sediment transport processes linking them (pathways). Sediment transport pathways include both alongshore and cross-shore processes, and therefore cells are best represented in two-dimensions. They are natural management units with a physical basis and commonly cross jurisdictional boundaries.
Sediment cells provide a summary of coastal data in a simple format and can be used to: 1. Identify the spatial context for coastal evaluations; 2. Provide a visual framework for communicating about the coast with people of any background; 3. Support coastal management decision-making; 4. Support a range of technical uses largely relating to coastal stability assessment, such as interpreting
historic trends, understanding contemporary processes and basis for projection of potential future coastal change; and
5. Reduce problems caused by selection of arbitrary or jurisdictional boundaries.
Boundaries of sediment cells have been identified for the Vlamingh coast between Cape Naturaliste and Moore River (Guilderton) in Western Australia. The region also extends along the Garden Island Ridge, including Garden Island and Rottnest Island. Nine primary cells, 40 secondary cells and 81 tertiary cells were identified between Cape Naturaliste and Moore River. Ten of the secondary cells and 21 of the tertiary cells are located on the Garden Island Ridge. The cell hierarchy for the Vlamingh coast is presented as maps and tables in this report, and in electronic datasets available from the Department of Transport. They were defined in three steps through selection of:
1. Points along the shoreline (beachface); 2. Offshore and onshore boundaries; and 3. Alongshore boundaries connecting the beachface points to the offshore and onshore boundaries.
This focuses on boundary definition at the beachface where the highest rates of sediment transport are likely to occur.
The cells have been mapped as a hierarchy of primary, secondary and tertiary levels to incorporate three space and time (spatio-temporal) scales. This hierarchical representation of cells gives a basis for implementation of integrated planning and management at a number of scales, from small-scale engineering works, through to large-scale natural resource management.
• Primary cells are related to large landforms, and are most relevant to potential change in large landform assemblages or land systems over longer coastal management timescales of more than 50 years.
• Secondary cells incorporate contemporary sediment movement on the shoreface and potential landform responses to inter-decadal changes in coastal processes.
• Tertiary cells are defined by the reworking and movement of sediment in the nearshore and are most relevant for seasonal to inter-annual changes to the beachface.
Common use of cells is intended to facilitate better integration of coastal management decision-making between governance, science and engineering at a regional and local level.

IntroductionThis report presents a hierarchy of sediment cells along the Vlamingh Coast for application in engineering, science, planning, management and governance of the region.
Sediment cell boundaries were mapped and identified at three spatio-temporal scales, along approximately 350km of the Western Australian coast between Cape Naturaliste and the Moore River. The area includes the inner continental shelf and coastal lands of the Vlamingh Region in the southern Swan Coastal Plain, including Garden Island and Rottnest Island (Figure 1; Figure 2; Figure 3; Appendix A). The three scales range from small, local landforms and the day-to-day processes affecting them to large coastal systems changing over millennia in response to global processes. At each scale the cells identify boundaries within which to consider the potential implications of proposed coastal engineering works as well as for assessment of coastal planning and management practices.
The hierarchy of cells facilitates understanding of contemporary sediment movement, encourages projection of future coastal change at a conceptual level, and establishes a context for qualitative investigations. Additionally, the hierarchy is intended to assist identification of differences in the processes driving coastal change at each scale.
Cells within this report are labelled according to a system described in Cell labels.
What are sediment cells?Sediment cells are spatially discrete areas of the coast within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange, often described using sediment budgets. Each includes areas of sediment supply (sources), loss (sinks), and areas through which sediment is moved between sources and sinks (pathways)1. These components are illustrated in Figure 4 for all levels in the hierarchy. Cells are natural management units with a physical basis and commonly cross jurisdictional boundaries.
Box 1: Literature on sediment cells
Sediment cells are spatially discrete areas of the coast within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange, often described using sediment budgets. Extensive global literature related to sediment cells and sediment budgets is available and has previously been reviewed2,3,4,5,6,7,8. The literature includes a number of terms similar in meaning to coastal sediment cell, with slight disparities in their use, although the broad concepts underpinning cell identification and sediment budget estimation are well established6.
Alternative terms for coastal sediment cell at varied spatial scales are littoral cell1,9, coastal compartment10, coastal sector11, beach compartment or coastal segment12, sediment cell with smaller coastal process units or sub-cells13, coastal cell14, process defined management unit or coastal management unit15,4, coastal tract5 and three nested systems of coastal behaviour systems , shoreline behaviour units and geomorphic units16. The term sediment cell is used in this report for the Vlamingh Region.
Sediment cells are commonly identified as self-contained where little or no sediment movement occurs across cell boundaries16,8. This concept is most applicable at a broad scale, such as when defining the scale and limits of coastal investigations5. Restriction of sediment movement is not a fundamental characteristic of cells at a fine scale or those not markedly compartmentalised by extensive rocky headlands. The cell approach retains meaning for these coasts, although their cells may have substantial sediment exchange across their boundaries2,17.
Constraints to sediment transport vary over time for different spatial scales and types of cell boundaries. For example, some rocky headlands are bypassed under infrequent high-energy conditions, but are a major constraint to sediment transport on a seasonal basis. Similarly, on sandy coasts cell boundaries may correspond to ephemeral areas of sediment transport convergence which indicate zones of reduced transport18,19. This variability in sediment bypassing at boundaries prompts the incorporation of time-dependence between levels within a cell hierarchy10, with the boundaries of the larger (primary) cells being related to longer-term processes.

Cell boundaries defined in this document extend landward from points on the shoreline to include terrestrial landforms, and seaward to encompass the nearshore marine environment in which waves and currents are most active. The offshore and onshore boundaries of cells should be determined by the scale of sediment transport processes operating within a cell, as well as by topographic features.
Why use sediment cells?Sediment cells define natural units with each cell encompassing adjoining marine and terrestrial environments. The cells thereby provide a base for integrated coastal management in which the components of each cell is considered holistically as an interactive system. In this context sediment cells aid interpretation of historic trends, add to an understanding of contemporary processes and provide an important basis for projection of future coastal change. The objectives of determining a three-scale hierarchy of cells were to:
• Identify sediment cells which are recognisable as natural management units for regional, sub-regional and local scale coastal studies;• Establish a framework for linking marine and terrestrial projects that is founded on the connectivity of subaqueous and submarine coastal landforms, and which supports integrated coastal planning and management; • Identify areas of coast where sediment budget estimates may provide a useful tool for coastal planning and management based on landforms at varying time and space scales20,21,22; and• Avoid clashes of policy and practice where coastal management is required by neighbouring coastal agencies, particularly local government authorities, within single or adjacent cells.
Characteristics of the sediment cell approach which make it a fundamental tool for assessment of hazards to land use caused by coastal change are that23:
• There is a plausible connectivity of geology, landform and hydrodynamics for coastal evolution and change that can be established and used in identification of the cells24; • It focuses on the integration of coastal and marine processes with landform responses to them rather than more static, quasi-equilibrium approaches such as those forming the basis for numerical models of beach profile change; and• The consistent methodology applied to identifying the cell hierarchy facilitates up-scaling and down- scaling in assessments of coastal change, a capability recommended in the assessment of coastal vulnerability to meteorologic and oceanographic change25.

The Vlamingh coastCoastal landform development on the microtidal Vlamingh coast, with low present-day supply of sediment, is subject to substantial control by the geologic framework. Control occurs through interaction of the fixed rocky topography, comprising the framework, with coastal processes and available sediments. The framework for the Vlamingh coast has been described at a variety of scales as part of a series of large-scale coastal compartments identified for the whole Western Australian coast26.
Modern Holocene sediments and inherited, remnant landforms abut and overlay the geologic framework. Both are reworked by present-day processes, although typically less for remnant landforms. The partly repetitive patterns of reworking define sediment transport behaviour at all scales.Landforms of the Vlamingh region include:
1. Sand flats, sediment lobes, sand banks and shoals between reef gaps;2. Flats, subtidal terraces and sand banks spilling into nearshore basins in the inshore waters; and3. Tombolos, spits, cuspate forelands and coastal dune barriers along the coast34,35.
These landforms provide an indication of the source areas, transport pathways and sinks; although they need to be established in relation to the processes driving coastal change.
The spatial distribution of alongshore sediment supply is affected by the degree of bypassing at rocky coastal features and engineering works. This varies with shoreline aspect and may therefore be subject to decadal-scale fluctuations. Further offshore, discontinuous reef ridges and inshore reef chains provide a leaky constraint to onshore and offshore sediment movement. Shoreward exchange of sediment typically occurs through gaps in the reef chains and may result in pulses of sediment transport to landward. More commonly, material is moved offshore through reef gaps and is lost from the nearshore system. At the shore, the geologic framework in the form of cliffs and bluffs may constrain sediment transport to landward.
The geologic framework provides a context for identification and description of sediment cells. However, transition from the fixed-structural, broad-scale geologic framework of the compartments to the functionally highly-variable, fine-scale sediment cells commonly includes a change in the balance of processes affecting the shore. For example, offshore currents driven by tides or winds may be significant to coastal evolution at a broad scale but not at a local scale where waves are likely to be dominant. This implies there is potential for process-landform interactions to generate errors at a broader or finer scale than a specific scale under investigation. The broader scale interactions commonly are apparent as trends whereas finer scale interactions contribute to the variability of the system being investigated.
Further information on geology, geomorphology, landforms, meteorological and oceanographic processes for the Vlamingh Region is included in previous work undertaken in the areae.g.11,27,28,29,30,31,32,33. Additional geology and geomorphology information is included in the WACoast34,35 database, the Sea to Scarp resources study36 and from a country-scale study of Australian beaches37. Information on terminology used in this report is contained in previous reports26,38,39 and global publications40.
12
Methods for the definition of sediment cellsCoastal sediment compartments, cells and sectors have previously been investigated along large sections of the Vlamingh Region11,41,42,43,44. A hierarchy of large-scale compartments was defined for the whole Western Australian coast26 to provide a geological context for coastal processes within each compartment, hence supporting identification and description of sediment cells.
In the present analysis, techniques originally established for the Vlamingh Region45, with some modification of terminology, have been applied to map sediment cell boundaries. This is a revision of the original Cape Naturaliste to Moore River report, made available in 2012, to ensure a consistent format that was adaptable for the whole Western Australian coast. Notably, the technique used to identify and map sediment cells in the Vlamingh Region is modified for the Mid-West, Northampton and Pilbara Regions46,47,48. It is expected that further revision of the criteria used (Figure 5; Table 1; Table 2; Appendix C) will be required for application to other parts of the Western Australian coast or elsewhere.
A threefold hierarchy of cells was defined by the type and shape of landforms present as well as the frequency of coastal processes and potential landform responses relevant to each scale. The primary cells are larger and the tertiary cells are smaller. Each primary cell is related to a functional coastal land system, whereas the secondary and tertiary cells identify specific coastal landforms and landform components at increasingly detailed scales. Further offshore, primary cells may extend to a continental shelf feature well offshore, whereas a tertiary cell may capture seasonal to decadal nearshore processes. At each scale, cells are likely to vary in area based on the dimensions of the geologic framework containing the coastal landforms or landform elements being considered, together with meteorologic and oceanographic processes driving coastal change.
Tasks undertaken were based on available data, and involved:1. Review of available literature to determine prevailing regional and local processes driving geomorphic change, including their temporal and spatial attributes;2. Identification of the geologic framework and environmental context in which processes operate;3. Establishment of criteria to identify cell boundaries at each level in the hierarchy of spatial scales indicated in Task 1;4. Application of the criteria along the Vlamingh coast between Cape Naturaliste and Moore River to identify sediment cells;5. Preparation of digital datasets and maps showing the cells at each of the three levels in the hierarchy; and6. Comparison of potential differences in the morphodynamic processes active at each level in the cell hierarchy.
Information used to define the cellsPoints along the shoreline that separate sediment cells were derived using the existing knowledge base of the coast, remotely sensed datasets and landform digital datasets (Table B.1 in Appendix B). Datasets used were:
1. Landgate Mean High Water Mark (MHWM) shoreline compiled to 2006; 2. Department of Transport nearshore and inshore LiDAR, Department of Transport nautical charts and isobaths; along with Australian Navy hydrographic charts and isobaths; 3. Onshore geology and geomorphology (including landforms) from Geological Survey of Western Australia34,35;4. Digitised foredunes, frontal dunes or the foreshore reserve prepared for this project by Geological Survey of Western Australia.5. A shaded relief model from the Geological Survey of Western Australia;6. Aerial orthophotography from Landgate; and7. High-angle oblique aerial photography from Geological Survey of Western Australia34,35.
13
These datasets cover most of the Vlamingh Region but vary with respect to time, spatial scale of capture and level of resolution. These factors limit use of the project datasets which may be reviewed as more detailed information becomes available. For example, the original mapping of coastal landforms was completed in 1985 to 1987 from unrectified stereoscopic aerial photography at a scale of 1:20,000. This scale is adequate for the identification of onshore cell boundaries at a primary and perhaps secondary cell scale but is inadequate at a tertiary cell scale. The information from which the secondary and tertiary cell onshore boundaries were determined also included recent oblique aerial photography, the shaded relief model, 2011 field surveys and landform mapping at 1:2,000-scale using 2006-2008 aerial orthophotomosaics34,35. LiDAR imagery, nautical charts, nautical isobaths and 2006-2008 aerial orthophotomosaics were used for delineation of the offshore boundaries and marine sections of the alongshore boundaries at all cell levels.
Additional information, particularly at a local scale, may facilitate refinement of the cell boundaries. In no particular order the extra information could include:
1. Local seismic surveys to determine rock coverage and depth of sediments; 2. Sediment distributions; 3. Long-term analysis of aerial photographs for dune activity; 4. Benthic habitat information; 5. Extension of LiDAR bathymetry north of Two Rocks; and 6. Contemporary and projected local variations in water levels, waves, currents and winds.
For example, detailed assessment of sediment characteristics and processes contributing to their distribution is useful for boundary verification49 (see Detailed evaluation of coastal behaviour). An ongoing review process, say every 10 years, may allow the implications of observed coastal change to be incorporated.
14
Cell boundariesA threefold hierarchy of cells is considered for the Vlamingh coast with each cell represented as two-dimensions because sediment transport pathways include both alongshore and cross-shore processes. Each cell may be thought of holistically as a collection of marine and terrestrial landforms, inter-related by sediment exchange between the landforms.
In this study, points along the shoreline separating the cells have first been identified (Table 1), followed by offshore and onshore boundaries (Figure 5; Table 2). Offshore and onshore boundaries are connected by mapping through the beachface points at the shoreline (Table 1). This sequence provides a focus on the alongshore boundary definition at the shoreline, and therefore on beachface processes, while being aware that significantly higher rates of sediment transport occur in this zone.
Alongshore cell boundaries (beachface points) are principally determined by one or several geologic, geomorphic or engineered features at the shoreline (Table 1). Each alongshore boundary has marine and terrestrial sections that connect the offshore and onshore cell boundaries through the beachface point (Figure 5). Distinctions between morphology and processes at each sediment cell scale are incorporated in criteria used to identify the beachface points and cell boundaries. Separate criteria are described for each level in the hierarchy (see Primary cells, Secondary cells and Tertiary cells). Sediment cells with cliffed or engineered coasts may have alongshore boundaries with no terrestrial section where the beachface point is coincident with the Landgate MHWM to 2006.
A list of features used to determine the alongshore boundary lines for marine and terrestrial sections is included in Table 1. Those identifying the marine section of the alongshore boundaries provide some restriction to sediment transport at varying timescales: from greater than 100 years for primary cells to inter-decadal and higher frequency timescales for tertiary cells. The terrestrial section of alongshore boundaries is the limit of, or discontinuities in, the relative coastal land system or coastal landform between adjacent cells at the scale of interest. Relevant Holocene coastal land systems are used at a primary cell scale, with foredune plains and parabolic dunes at a secondary scale and frontal dunes or foredunes at a tertiary scale. Exceptions occur on islands, engineered coasts and cliffed coasts where there is no terrestrial section of the alongshore boundary. In places where there is no variation in the land system or landform landward of the beachface point, a notional boundary is mapped as a landward extension of the marine boundary line through the beachface point to the onshore boundary along a similar trajectory or orthogonal to the coast (e.g. Warnbro in Figure A.9 in Appendix A).
Points along the shore separating the cells are characterised according to the restriction of sediment transport (open or closed); the extent of the restriction (point or zone) and the potential for migration (fixed or ambulatory). For example the apex of a rocky headland is defined as a fixed point whereas a salient sustained by wave convergence behind a large area of reef is recognised as a fuzzy boundary or zone, although it is geographically fixed. Ambulatory features may be points (e.g. large spits) or zones (e.g. deltas). By definition, an alongshore boundary cannot be ambulatory and closed.
Primary cells evolve over centuries and millennia. They are linked to coastal land systems50,51,52,53,54,55,56,57,58 and broad marine systems11,33. Secondary cells are based on large coastal landforms34,35,36 subject to inter-decadal change. Tertiary cells are based on coastal landforms subject to change on an inter-annual scale, as well as beachface features restricting sediment transport at a seasonal scale.

Table 2: Criteria for mapping onshore and offshore boundaries in the Vlamingh RegionVariation of criteria will be required when applied to other coastal regions.
Note: 1. Isobaths were mapped to the vertical datum of Australian Height Datum (AHD).
Primary cells: geologic framework and long-term change in morphologyPrimary cells (Figure 2) encompass the geologic framework controlling long-term evolution of the coastal land systems, such as coastal barriers, cuspate forelands and large sediment banks. Although substantial changes to these large land systems occur at time scales longer than 100 years, the changes are general trends when considered over coastal management time scales.
At the shoreline, boundaries of primary cells are defined by one, or a combination of, rocky structures, large accretionary landforms, changes in coastal aspect and large engineered structures that restrict sediment transport at a decadal scale. In the Vlamingh Region, five of 13 alongshore cell boundaries of primary cells are defined by a rock structure. This includes rocky headlands at Cape Naturaliste (R06A), Second Head (R06E) and Point Casuarina (now Bunbury Harbour, R06B); and rocky salients at Mallee Reef salient (R06I) and Moore River (northern extent of Cell R06I). A rocky salient is also present at Cape Bouvard (R06C) reflected in the geomorphic feature criterion. Point Casuarina and the Swan River mouth were rocky salient, now extended by Bunbury Harbour (R06B) and the South Mole Fremantle (R06F) engineered structures respectively.
Accretionary landforms include the toe of banks, such as South Sands at Becher Point (Cell R06C12), Southern Flats at Palm Beach Rockingham and Parmelia Bank at Woodman Point groyne (Cells R06D and R06E);
18
salients, such as Yanchep (Cell R06H) and Mallee Reef (Cell R06I); and cuspate forelands, such as Pinnaroo Point (Cell R06G). The large basin within Cockburn Sound (Cell R06E) is a primary cell nested within cell R06D due to the protection provided by Garden Island, Southern Flats and Parmelia Bank. Additional basins included within broader primary cells are Warnbro Sound (R06C), Owen Anchorage and Gage Roads (R06D).
The offshore boundary of primary cells is the -30m AHD isobath or depth contour (Table 2). It is located on the inner continental shelf and seaward of offshore reef ridges impounding inshore lagoons and basins. Selecting this depth includes the outer margin of the shore-parallel ridge of limestone reefs within the cell and provides separation between large-scale ocean currents and the complex inshore circulation patterns. LiDAR imagery and aerial photography reveal migratory bedforms across sand banks and reefs and suggest a considerable volume of sediment transport presently occurs along the outer margin of the ridge and spills landward. This may be primarily related to the Holocene rise in sea level33,59,60 but it also currently occurs as pulsational migration of sand waves and shoals61,62.
The onshore boundary of primary cells is the landward extent of Holocene accretionary land systems, including the foredune plains, transgressive dune systems and the landward shores of barred estuaries and wetlands58,34. Exceptions to this are moderate to high cliffed coasts without dunes to landward, engineered coasts with extensive shore parallel structures without dunes to landward and for Garden Island, which consists of only Holocene Land systems, the central ridge line of the island was used (Table 2). The Landgate MHWM to 2006 has been used for cliffed and engineered coasts (Appendix B). All sections of coast with Landgate MHWM to 2006 as the onshore boundaries require further investigation at a more detailed scale. For example, there may be small pocket beaches or sections with lower elevation rock or engineered structures that have sediment exchange to landward.
The exceptions of cliffed coasts, engineered coasts and central ridge lines of islands also apply at the more detailed, secondary and tertiary cell scales. The mapped representation of the onshore boundary on mixed rock and sand coasts at a secondary and tertiary scale may be located landward of the primary cell onshore boundary as the smaller sections of sandy coast were mapped at the 1:2,000 scale, rather than the 1:20,000 scale for the primary cells.
Secondary cells: regional-scale processes and morphologySecondary cells contain the broad patterns of contemporary (inter-annual to decadal) sediment movement on the inner continental shelf (Figure 2).
The beachface points on the alongshore boundaries may be fixed or ambulatory (Table 1; Table 7). Fixed boundaries include rocky outcrops restricting sediment transport at an annual scale such as at Point Piquet (R06A2), as well as large engineered structures, such as Garden Island causeway (R06D16) and Woodman Point (R06D21). Ambulatory boundaries are associated with areas of convergence of sediment transport which occur on many of the accretionary landforms such as forelands and salients; for example North Becher Point north of Mandurah (R06C12). At the secondary cell scale, many ambulatory boundaries have been stabilised using engineering structures such as Norman Road near Busselton (R06A3) and Catherine Point south of Fremantle (R06D22).
The offshore boundary of secondary cells follows the -15m AHD isobath closest to shore (Table 2). This depth is near the seaward margin of shore-parallel limestone ridges close to shore or the toe of large sediment banks. Selecting this depth encompasses contemporary sediment transport by nearshore wave63 and current processes within the cell, including dispersal of locally derived biogenic material64,61,65,66. Basins and dredged shipping channels function as sediment sinks and are included in secondary cells only to the toe of sediment banks spilling into them (e.g. Jervoise Bay Bank in Cockburn Sound, R06E18). Warnbro Basin is a remnant basin that is largely inactive at the inter-decadal scale. It has been excluded for depths deeper than -15m AHD (R06C12, Figure A.10 in Appendix A). If the cell contains multiple reef ridges, the offshore boundary is the toe of the reef ridge furthest inshore even if the toe is less than -15m AHD depth for example Comet Bay (R06C10) and Burns Beach salient to Two Rocks (R06G29 to R06H31).
19
Onshore boundaries of secondary cells include potential landform activity at an inter-decadal scale. The onshore boundary corresponds to the landward extent of the foredune plain, narrow parabolic dunes or frontal dunes as defined by the Quindalup Q4 category50 or its equivalent. As noted above, an exception to this are low to moderately high cliffed coast without dunes or engineered coasts with extensive shore parallel structures without dunes to landward, where the Landgate MHWM to 2006 is used as the onshore boundary (Table 2). In developed areas, such as Mersey Point (R06D13), the foreshore reserve has been used to establish the onshore boundary. In flood-prone land with installed mitigation works, such as Bunbury (R06B5) and Mandurah (R06C10), the landward extent of estuarine landforms or made ground is used as the onshore boundary. Sediment activity could extend beyond the onshore boundaries of secondary cells in some circumstances.The central line, watershed or ridge line is used as the onshore boundary for promontories and islands where the onshore boundaries of secondary cells are coincident (e.g. central line of Woodman Point, R06E19 and R06D20).
Tertiary cells: local-scale, short-term processes and morphologyTertiary cells incorporate the reworking and movement of sediment near the shore and associated potential seasonal to inter-annual landform response (Figure A series in Appendix A). Tertiary cells perform similar functions to those of secondary cells, often on a finer scale. Their alongshore boundaries and offshore boundaries coincide in some places. Beachface points on the alongshore boundaries of tertiary cells (Table 1), along with onshore and offshore boundaries (Table 2) are highly subject to change. They may be transgressed by extreme events and modified by low frequency coastal processes.
Tertiary sediment cells were identified for the Vlamingh coast, including Garden and Rottnest Islands, and excluding the small reefs, islets and west of the shipping channel through Success and Parmelia Banks.
Beachface points on the alongshore boundaries of tertiary cells restrict sediment transport at a seasonal to inter-annual scale. Fixed boundaries include rocky outcrops along the shore, such as Bickley Point (R06DRI1a) on Rottnest Island. They also include engineered structures, such as marinas and harbours, which restrict sediment transport in depths shallower than the offshore boundaries (-5m AHD, -7m AHD, or -15m AHD isobaths). The installation of engineered structures potentially may change the alongshore boundaries of tertiary cells and lead to development of new cells. Ambulatory boundaries are associated with zones of convergence or divergence associated with local wave refraction and diffraction patterns19,17. Ambulatory boundaries at a tertiary cell scale may be located at the tip of accretionary landforms, such as at Pinnaroo Point (R06F27c) or Mersey Point (R06D13a), as the change in aspect and wave sheltering restrict sediment transport at a seasonal to inter-annual scale.
The offshore boundaries of tertiary cells were mainly defined by three isobaths (Table 2):1. The -15m AHD isobath has been used in the nearshore zone of the relatively unsheltered and unconsolidated sandy coast between Bunbury and Mandurah (R06B5a to R06C9b). Based on empirical formulae from the USA the majority of sediment transport by waves and wave driven currents take place in this zone63;2. The -7m AHD isobath was used in the lee of large natural structures with reduced sheltering and where substantially attenuated swell is a significant component of the wave regime. Areas where this occurs include sections of Geographe Bay to Bunbury (R06A2c to R06A4b), Comet Bay to Cape Peron excluding Warnbro Sound (R06C10a, R06C10b and R06D13a to R06D14c), Fremantle to Trigg (R06F25a to R06F26d), and the exposed western side of Garden Island (R06DGI4c to R06D14d); and3. The -5m AHD isobath was used for more sheltered sections of the coast. In places, this approximately corresponds with the toe of reef platforms, subtidal terraces or large sand shoals flanking the shore. It is applicable where sheltering by offshore reefs and islands results in locally generated wind-waves and partially attenuated swell being prevailing components of the wave regime.
Isobaths have not been used to establish offshore boundaries where beaches are perched on rock platforms with subtidal cliffed seaward margins, such as near Two Rocks (R06H31a). The seaward margin of the rock platform is used in such circumstances. In places where there are wide terraces or sediment banks the toe of the feature has been used, such as on the sheltered eastern side of Garden Island (R06GI2a to R06GI4f).
The onshore boundaries of tertiary cells indicate the landward extent of average seasonal processes, which may be superseded annually. Onshore boundaries are either alongshore swales between the foredunes and
20
the frontal dunes or the landward toe of the frontal dunes if foredunes are eroded or absent (Table 2). These landforms are highly changeable. It is likely discrepancies will occur between what was mapped and what may be observed at present or in the near future. Such discrepancies should signal a requirement for more detailed mapping and accurate identification of boundary and landform change at a tertiary scale. The onshore boundaries of tertiary cells are not indicative of the landward extent required for engineering, planning and management investigations. However, they may be used as a marker to establish higher frequency changes at the shore.
Exceptions to the landward extents of landforms as onshore boundaries are cliffed coasts or engineered coasts with extensive shore parallel structures (e.g. seawalls) without dunes to landward; and the central line on promontories or islands (e.g. Garden Island).
Rivers, streams and drainsThe main estuarine systems of the area are the Vasse-Wonnerup, Collie and Preston, Peel-Harvey, Swan-Canning and Moore River estuaries (Figure 1). There are also many small streams and wetland drains that extend to the coast. Most of the ocean entrances of rivers, streams and drains have barred mouths that can breach and flow intermittently67,68. The mouths can switch from being a sediment source during flood events, to potentially acting as sediment sinks during intervening periods.
Onshore boundaries for rivers and drains in the Vlamingh Region have been represented in datasets and the figures in this report as a truncation between the dune and alluvial landforms on opposite banks of the rivers or as a truncation across reclaimed ground in Port areas. In this respect the onshore boundary does not comprehensively represent the onshore extent of estuarine processes within each river or drain. Further investigation of landforms and sediment budgets adjacent to rivers, streams or drains should include:
• The landward extent of the majority of sediment exchange, which is often indicated by flood-tide shoals within estuary mouths.• All alluvial landforms with connection to the coast; • The potential for alluvial landforms to become estuarine with changing climatic conditions; • The capacity for flooding; • Sediment transport along the river; • Maintenance dredging or bypassing at Port Geographe, Bunbury, Dawesville, Mandurah and Fremantle69; and • Sediment transport fluxes associated with opening and closing of sand bars across river mouths.
Marine sections of the alongshore cell boundaries may follow the submarine paleo-channels of rivers, which are likely to trap sediment or divert sediment movement. For the Vlamingh coast the marine sections of some primary boundaries follow paleo-channels of the Collie River (Bunbury Harbour R06B), Swan River (South Mole Fremantle R06F) and Moore River (Guilderton R06I). At a secondary cell scale engineered features restrict sediment and control the alongshore boundaries at Bunbury Harbour and South Mole Fremantle, with the paleo-channels of the Capel River (R06A3) and Moore River providing the main control. The barred Moore River mouth is functional within a tertiary cell and does not constitute a boundary at that scale.
Cell labelsThe cell labelling convention follows the direction of prevailing littoral drift according to:
1. Region – increasing order of R01, R02 to R13 from the South Australia border26. The Vlamingh Region is region R06;2. Primary cell – upper case letter resetting for each region;3. Secondary cell – number resetting for each region. Rottnest Island and Garden Island secondary cells are labelled RI1 to RI4 and GI1 to GI4 respectively; 4. Tertiary cell – lower case letter resetting for each secondary cell with letters increasing in the direction of littoral drift or clockwise around islands, for example 14a; and5. Quaternary cell – Roman numeral resetting for each tertiary cell, for example 14ai. Quaternary cells were not applicable in this investigation.
Vlamingh cells are labelled to the tertiary cell, for example R06A1a, from south to north following thedirection of prevailing littoral drift.
21
Nine primary cells, 40 secondary cells and 81 tertiary cells were identified along the Vlamingh coast between Cape Naturaliste and the Moore River. The hierarchy of cells is presented as maps, tables and electronic datasets available from the Department of Transport (Table 3), along with the coastal sediment cells spatial browser (see Note 1 below Table 3).

Cell boundariesThe alongshore spatial scale of cells in the Vlamingh Region varies with wave exposure, geologic framework, sediment availability, aspect and its location on an island. The mean length of cells was 44km (13-87km), 10km (0.7-28km) and 5km (0.7-20km) for primary, secondary and tertiary cells respectively (Table 6). Larger cells in the size ranges are present on open coasts with reduced reef sheltering and large rock outcrops, with smaller cells in the size ranges on coasts with increased geological control, such as coasts with tombolos or in the lee of large islands. Secondary and tertiary cell boundaries may be coincident for coasts that are open or have inherited features.
There is some consistency in scale with littoral cells reported from elsewhere, overseas and on the WA coast. Spatial scales of primary cells (13-87km) are smaller than the littoral cells in England, Wales and Scotland (50-300km)13,14 and the Pilbara Region (100-455km)48; and at a similar scale to cells in the Mid-West and Northampton Regions (37-78km, 33-66km)46,47, California (10-95km)20 and Hawkes Bay, New Zealand (20-60km)70. The Vlamingh Region has more smaller primary cells than the adjacent Mid-West Region46, because of large islands within the primary cell boundaries and the more continuous offshore ridges providing more sheltering in the Vlamingh Region. The local primary and secondary cell scales correspond with sub-cell scales in the United Kingdom. The comparison across the hierarchy of cells provides confidence in linking cell dimensions to the geologic framework, sediment availability and different metocean processes driving shoreline change at each scale.
22
Nine (69%) primary cell boundaries are also secondary and tertiary cell boundaries (Table 5). Exceptions occur for large inherited features in Warnbro Sound (R06C), the edge of Parmelia Bank (R06D/R06E) at a remnant spit (R06D/R06E); and a barred river mouth at Guilderton (R06I). Thirty-seven (91%) secondary cell boundaries are also tertiary cell boundaries, with 46 (55%) unique tertiary cell boundaries.
The cell hierarchy and boundary character classification (Table 4; Table 7) reveal the complexity of the coastal system of the region which has varied rock control and inherited features. The majority (≈85%) of boundaries are open at all three scales with varying degrees of sediment transport leakage. Notably, sediment flow directions may be reversed with changes in meteorological and oceanographic conditions, with some boundaries effectively closed for one sediment transport direction.
Boundaries are ambulatory (≈30%) where rock control is on the sub-tidal part of the shoreface and may be defined as a zone where there is limited to no rock control on the beachface. At all scales, half of all cell boundaries are points and half are zones, with more than 60% of mainland tertiary cells characterised as a zone. There are more ambulatory boundaries at the tertiary scale (39% total with 48% on the mainland) than the primary scale (23%). Landforms adjacent to tertiary cell boundaries are susceptible to variation as a result of both sub-tidal and inter-tidal rock control.

Along coast variation of sediment cellsGeographic differences in geology, sediments and processes cause alongshore variation in the characteristics of sediment cells over both regional and sub-regional scales. These differences change the relative influence of the criteria used to define sediment cells boundaries. They identify which attributes best define the sediment cells and at what scale.
Intra-regional variation in sediment cells of the Vlamingh Region is described according to primary cells, linkages with the seafloor terrain, onshore sedimentary landforms and coastal processes. The Vlamingh Region comprises offshore reefs, a series of mainly submerged limestone ridges and islands; submarine rocky pavement; inshore basins and inter-barrier lagoons, sea grass meadows, sand banks, shore platforms, cliffs and bluffs; estuaries; and several types of barrier dunes along the shore including mobile sand sheets34,35. The barriers include broad salients, cuspate forelands, tombolos, foredune plains, beach ridge plains and high ridges of parabolic dunes. Some foredunes and parabolic dunes impound back-barrier lagoons. The distribution of these landforms differs between the four broad areas comprising the region.
The coast is fronted by a shelf that is approximately 50km wide out to 50m depth33. Changes in the plan form of the reefs and cliffs, their position of outcropping along the shore; sheltering by Cape Naturaliste and islands of the Garden Island Ridge; and the development of large sedimentary landforms contribute to local variation in coastal aspect and exposure. Hence, there is significant variation in the relative intensity of meteorological and oceanographic processes affecting the shore.
The southern part of the region (Cells R06A and R06B) corresponds with the sector between Cape Naturaliste and Robert Point identified previously11. The southern cell (R06A) includes the broad shallow waters of Geographe Bay and sandy beaches between granite outcrops from Cape Naturaliste to Point Daking to basalt outcrops at Bunbury. The bay has a number of rivers and streams that discharge into estuaries, estuarine and alluvial flats fronted by foredune plains (Point Daking to Forrest Beach) and barrier lagoons (Forrest Beach to Point Casuarina). The foredune plains have a contemporary sand supply from migratory bars. Cell R06B is more exposed to swell waves, with shore-parallel reefs and some areas of rock outcropping along the shore, particularly as cliffs and bluffs in the north. Dunes and parabolic dunes impound lagoons to landward. Human intervention at Bunbury Harbour and the Cut transfer erosion along the coast due to strong alongshore sediment transport potential in this area.
Between Mandurah and Fremantle (Cells R06C to R06E) the coast is sheltered by limestone ridges and inshore basins with Five Fathom Bank Ridge and Garden Island Ridge including the large islands of Garden Island and Rottnest Island. A third ridge, the Spearwood Ridge, outcrops in areas along the coast as beach rock, bluffs and cliffs. This section of coast has been the main area of Holocene sediment deposition along the coast from Cape Naturaliste to Fremantle. As sea level rose to its peak in approximately 7,000-6,000 years ago sediment was pushed landward through low sectors of reef to form large banks and sedimentary accumulation features along the shore, such as the Rockingham-Becher foredune plain. Inshore basins were formed adjacent to large sand banks in Warnbro Sound, Cockburn Sound (nested cell R06E) and Owen Anchorage.
The Swan River, its paleo-channel and the river training walls (north and south mole) are the southern extent of the next section of coast between Fremantle and the cuspate foreland at Hillarys (R06F). This cell is located in the lee of Rottnest Island, with dunes and sand sheets overlaying older Pleistocene limestone that outcrops at many locations along the shore; at Cottesloe, Swanbourne, and Trigg to Sorrento for example.
In the northern part of the region (Cells R06G to R06I) the shore is sheltered by three continuous ridge and reef chains as well as complex inshore reefs. The three ridges of Staggie, Marmion Reef and Spearwood are parallel to the shore. There is substantial variation in ridge height along the coast. This variation apparently contributes to the formation of coastal landforms such as the salients and cuspate forelands at Quinns Rocks and Wreck Point. Rock outcrops along the shore as subtidal pavements, inter-tidal platforms, small bluffs and headlands. Four marinas are located in these three cells, providing further interruption of sediment transport patterns and feedback affecting adjacent coastal landforms.
28
Inter-regional variation in sediment cells is summarised by comparing the criteria for mapping cells for the four regions of Vlamingh, Mid-West, Northampton and Pilbara. Criteria for defining sediment cells for the Vlamingh Region were more similar to the Mid-West46 and Northampton Regions47, than the Pilbara Region48. Despite the differences, a consistent approach has been used to determine the beachface point on the alongshore boundaries and follows the procedure described in the coastal compartments report26. Differences in criteria between the Vlamingh Region and Mid-West/Northampton Regions are related to engineering modifications and the presence of near continuous ridges formed by elongate reefs, large islands and basins in the Vlamingh Region (Appendix C). Differences in criteria between the Vlamingh Region and Pilbara Region is related to a shift in dominant forcing from waves in the southern region to tidal reworking, extreme waves and increased river activity in the Pilbara (Appendix C).

In this report, sediment cells are areas in which there is strong connectivity between marine and terrestrial landforms. Hence, they are natural management units, presented in a simple spatial format. Applications of sediment cells include identification of spatial context for coastal evaluations; a common framework for dialogue about the coast; support to coastal management decision-making and a range of technical uses largely relating to coastal stability assessment. Some uses of sediment cells are listed in Table 8 and briefly described below.
Table 8: Applications of sediment cells
Applications
ContextAs defined in this report, sediment cells provide an indication of a spatial area within which marine and terrestrial landforms are likely to be connected through processes of sediment exchange. This implies that either natural or imposed changes at any point in the cell may affect any other part, recognising such relationships are strongly bound by proximity. A fundamental use of sediment cells is therefore one of context, to identify an area that should be considered in a coastal study. Specifically, questions that should be considered are:
• Howmayanimposedaction,suchasinstallationofagroyne,affectthewidercoastthroughchangesto the sediment budget?• Havechangestothewiderareainfluencedlocallyobservedresponse?
Note that this does not mean that sediment cells must be used to define a study area or model area. These are typically smaller due to data or budget limitations.
A qualitative assessment within the sediment cells context is often valuable for problem scaling when dealing with coastal instability. Considering whether an observed issue is prevalent within a cell or adjacent cells may provide guidance on the type of management solutions available, and therefore suggest the form of technical advice most likely to be useful (Figure 6). For example (labelling corresponds to panels in Figure 6):
A. If there is a balance of erosion and accretion within a sediment cell, there is potential opportunity to manage the problem through coastal stabilisation works, which transfer stresses along the coast;B. For a coastal stability issue that is affecting the majority of a sediment cell, it is appropriate to improve coastal resilience, including techniques that improve the transfer of sand from the nearshore to the beach and dune system;C. If erosion and accretion occur differently between cells, it is possible that the stress can be more evenly distributed, including artificial interventions such as bypassing. However, limited natural sediment transfer at cell boundaries determine that balancing erosion and accretion requires long-term management;D. If erosion or accretion is prevalent across multiple cells, the issue is likely to be dominant in the long term. This typically requires a decision about where to focus the problem, such as through identification of sacrificial coastal nodes.

CommunicationA key feature of the sediment cell framework is its development from physical attributes rather than a jurisdictional basis. This highlights situations where communication between coastal managers may be necessary, and supports formation of strategic planning groups such as the Peron-Naturaliste Partnership (R06A to R06D) or Cockburn Sound Coastal Alliance (R06D and R06E).
The relatively simple spatial representation of sediment cells may be a valuable tool for communication between technical agencies and the general public. Recent application of coastal process connectivity mapping24 has highlighted the value of simple spatial tools to help explain the basis for coastal management decisions to a non-technical audience.
The value of communicating through a common spatial framework may also enhance dialogue between technical staff involved in different disciplines. The framework of sediment cells and coastal compartments are designed to be of use for coastal management across multiple scales, from engineering through to strategic planning26. However, the strong relationship between habitats and morphology71, includes links between catchments areas and sediment cells. This more broadly suggests that sediment cells may have value as natural management units when considering natural resource management or coastal ecosystem services.
Decision-makingRecognition of the inter-connected nature of marine and terrestrial landforms within a sediment cell may support simplified decision-making by coastal managers, including local and State government agencies.
For agencies managing large areas, sediment cells can be used for low-cost geographic screening, particularly when combined with the direction of net alongshore sediment transport. As the cells provide preliminary guidance regarding the possible extent of development impacts, the cells framework may be used to guide the distribution of infrastructure. For example, destabilising infrastructure may be preferentially excluded from a cell containing sensitive or high amenity coastal areas. Alternately, a largely isolated single cell may be identified as a strategic coastal node, with focused coastal protection works and interventions creating a minimised coastal footprint.
An objective of the sediment cells definition is to focus coastal managers’ attention upon the connected nature of marine and terrestrial landforms. This is intended to disrupt expectation that the whole coast under management can be made stable. For every effort toward stabilisation, the consequent trade-off should be clearly identified and understood. This way of thinking reduces the likelihood of tail-chasing through successive coastal stabilisation works.
31
Technical useA major technical use for sediment cells is to improve erosion hazard assessments by better integrating regional and local coastal change. Regional changes may include the effects of climate or sea level fluctuations and the consequent variations in sand supply. Local changes include storm responses and coastal interactions with natural and artificial structures. Improved knowledge of how local changes may have broader impact is essential to good coastal planning20,21,22,,72,73,74. Equally, refined understanding of how regional change influences local response can improve setback assessment75 and structural design76.
Sediment cells evaluated for regional processes should be identified based on the relative magnitude of local coastal change and the proximity to cell boundaries. Large-scale engineering works, such as ports and harbours, should be considered over the full hierarchy of primary, secondary and tertiary sediment cells to ensure adequate identification of possible effects. However, most planning and engineering investigations require consideration at a secondary cell scale as this incorporates broad sediment transport processes over inter-decadal timescales. If proposed works are unlikely to restrict sediment transport on an inter-annual scale, assessment may occur at tertiary cell scale. In all cases, proximity to a cell boundary may suggest the need to consider adjacent cells.
Landform information used to develop the sediment cells, including indications of sediment transport pathways and sinks, is equally important to the development of quantitative sediment budgets. Consequently, the sediment cells framework provides a useful spatial basis for the development of sediment budgets1,2,6. The effect of timescale on sediment budget variability is acknowledged along the Vlamingh coast, with ocean-estuary exchange and pulses of sand supply contributing to these fluctuations. A recent example of a detailed application of a sediment budget-based coastal assessment is the study in the Geraldton area of the Mid-West Region49 (Cell R07F).
Definition of sediment cells (and coastal compartments26) over multiple spatial scales supports the processes of upscaling and downscaling, where information collected or applicable at one particular scale is made meaningful at another larger or smaller spatial scale. Upscaling involves the aggregation of information from a finer scale, often sparse across the wider area. Downscaling involves interpretation of coarse scale information at a finer scale, usually through the use of additional information. The concepts of upscaling and downscaling are important tools for combining regional and local coastal change assessments, often using a sediment budget approach.
Connectivity of marine and terrestrial landforms is used as a basis for sediment cell definition. The identified landforms and pathways for transport may also suggest the key active coastal process and therefore indicate appropriate conceptual models for coastal dynamics. Mapping of coastal morphology in the Vlamingh Region has been described as part of the WACoast series34,35.
32
Although the cell boundaries have been presented as a spatial framework, they are based upon interpretation of geomorphic information. Therefore boundaries may require revision according to either the intended application or due to further relevant information being obtained. Common reasons to update the database describing the cells may include:
• Large-scalechangethatwillaffectcellconnectivity;• Coastalchangenearacellboundary;• Modificationduetoengineeringworks;or• Moredetailedevaluationofactivecoastalbehaviour.
Sediment cell connectivityDetermination of the number and scale of sediment cells used for coastal assessment should involve consideration of the magnitude and timescale of coastal change as well as the relative connectivity between sediment cells. It is appropriate to consider multiple sediment cells when evaluating larger or more sustained coastal change, or when assessing cells with moderate or high connectivity. Cell connectivity is indicated by the nature of the coastal boundary, with higher connectivity occurring where:
• Theboundaryisopenorambulatory;forexample,sedimenttransferoccurringacrossboundarieson salients and cuspate forelands;• Reversaloflittoraldriftdirectionisknowntooccur;• Thereisanonshorefeedofsediment;• Aboundaryislocatedonasedimentsourceorsink;or• Boundariesprovidingheadlandcontrolofestuaryentrancestocoastallowlands.
Investigation of coastal processes should recognise the potential role of connectivity between cells, including the relative significance of prevailing and extreme events in driving linkage of adjacent cells.
In situations where coastal change is substantial, such as coastal adjustment subsequent to mass deposition from a river system, or the potential impact of sea level rise over the next hundred years, there is potential for change to affect even rock boundaries. Users of the cell framework on mixed rock and sand coasts, such as the Vlamingh coast, should consider:
1. Sections of coast which have occasional outcrops of rock and are progressively eroding will potentially reach points where either the rock has reduced influenced on the coast, or a newly exposed area of rock starts to control the coastal configuration. These changes of coastal state may effectively alter sediment cell boundaries.2. The influence of rock features that control the coast through sheltering may change with sediment supply. The resulting sandy features, salients or cuspate forelands, may migrate under changing meteorological, oceanographic or sediment supply conditions. This can occur following a loss of offshore reef control, as has been reported for a calcarenite coast77, or if there is a reduction in sediment supply such as caused by Fremantle Port breakwaters (south and north mole).
Proximity to cell boundariesAs the influence of a local coastal change is strongest in its immediate vicinity, it is possible for the effect of a moderate change to be transferred across a cell boundary. In such a situation, adjacent sediment cells should be assessed simultaneously.
Modification due to engineering worksEngineering works may modify the nature of sediment cell boundaries and in some instances, mightcreate new boundaries. An example of modifying the cell boundary has occurred at the causeway toGarden Island (R0D15), where the influence of the rock structure interrupts the mobile sediments onthe bank of Southern Flats.
Modification of cell boundaries

Detailed evaluation of coastal behaviourDetailed coastal assessment, including sediment analysis, sediment transport assessment or higher frequency evaluation of coastal configuration may provide better representation of how the sediment cell boundary operates. Cell boundaries may need to be reviewed following such investigations.
Recent work in the Mid-West Region provides an example of how sediment analysis may be used to verify and resolve cell boundaries49. An overview of the study findings is included in the Mid-West Region cells report46. Useful studies in the Vlamingh Region containing previous sediment analysis are referred to in Table B.1 (Appendix B). An example is provided by the relationship between regionally varying oceanography and the resulting shelf sediments in the Vlamingh Region33. Processes affecting the distribution of sediments and variability in sediment supply from nearshore sources in the studies could be investigated to help develop sediment budgets.
Possible studies to further resolve cell boundaries requires consideration of how the cells are to be applied, the time and space scales and the range of landforms within the domain of interest. For example, when assessing over an extended time scale for climate change adaptation assessment, there may be sensitivity to buried rock. A program of seismic surveys could therefore refine the onshore boundary. A second example is where coastal dunes define the onshore boundary of secondary cells, as the degree of dune mobility and the time scale of change will directly affect the area of interest. In this situation, active dune movement may be identified through aerial photograph interpretation or sediment analysis.
Further work to increase the resolution of cell boundaries may involve:1. Ensuring the temporal and spatial resolution of data are consistent between datasets and fit for purpose at the scale at which they are being applied;2. Extension of the criteria used to identify the cell boundaries to include criteria describing sediment characteristics and the limits to their distribution;3. Identification of the potential for change of ambulatory boundaries at a local scale related to projected variation in climate and ocean processes, along with more detailed information of underlying rock structures; 4. Verification of sediment cells through determination of sediment character, composition, depth and distribution;5. Determination of the contribution of barred estuaries to cell functions; and6. Revision of cell boundaries in the event of large-scale engineering works, such as ports or harbours, restrict sediment transport at relevant time and space scales.
Proposed modification of cell boundaries should be presented to the dataset custodian, the WesternAustralian Department of Transport. The modifications should be presented in either ESRI Shapefileformat or as Google Earth KMZ files with metadata and supporting documentation. Department ofTransport officers will integrate the modifications into the geodatabase if deemed appropriate.

Appendix B Data setsTable B.1: Data Sources used for determining cell boundaries in the Vlamingh Region
Source Dataset
Context•Geological and geomorphological information and photographs contained in the WACoast1 database.
•Sediment information, with some examples provided in cited references2 .
Remotely sensed
datasets
•Bathymetry: Department of Transport nearshore and inshore LiDAR, Department of Transport (previously Department of Marine and Harbours) nautical charts and Department of Planning polygons derived from Department of Transport nautical charts. The LiDAR imagery was captured in 2009 and provides bathymetric detail at 5m grid spacing to approximately 25m below MSL3. All depths use the vertical datum of Australian Height Datum (AHD). Alternative information could have been used, however it was generally of a larger spatial resolution than needed, with reduced spatial accuracy. These datasets include the Australian Navy hydrographic charts, Geoscience Australia bathymetry, General Bathymetric Chart of the Oceans (GEBCO) bathymetry.
•Topography: Geological Survey of Western Australia shaded relief model derived from the Landgate high-resolution digital elevation model. Alternative sources include Department of Water onshore LiDAR, Landgate topographic contours and spot heights.
•Vertical aerial imagery: Landgate orthophotography from 2006-2008. Satellite imagery could be an alternative information source, but is generally of reduced spatial resolution and accuracy.
•Historic coastal change: Department of Transport shoreline movement plots4, including plan books DPI433, DPI67, DPI568, DPI374, DPI567 and DPI351. Historic aerial imagery can also provide context for coastal change, including recent changes identified by the time-series available through NearMap or Google Earth..
•Shoreline: The shoreline used as the basis for mapping is the Mean High Water Mark (MHWM) to 2006 prepared by Landgate and used by the Department of Environment and Conservation as the basis for the coastal compartment mapping5. This dataset is based on a combination of the cadastral and topographic coasts and is updated in areas as required based on government priority. It is unlikely to represent the location of the MHWM in 2006.
•Rivers: 1:1M and 1:250k scale rivers by the Department of Water.
Landform mapping
•Digital dataset of the Holocene dunes and other landforms at 1:20,000 scale to 3km inland of Landgate MHWM to 2006 as part of WACoast datasets1, unpublished digital datasets of landforms at 1:20,000 scale compiled in 1985-1987 by the Geological Survey of Western Australia and the Quindalup Q4 category6.
•Heads up digitising of foredunes, frontal dunes or the foreshore reserve at the 1:2000-scale..
•1:100k geology maps (GSWA) show the Holocene extent for primary cell onshore boundaries.

Same criteria used for Vlamingh and Mid-West Regions. Same criteria used for Vlamingh and Pilbara Regions, except engineering structures did not define any primary beachface points in the Pilbara. Vlamingh cells were defined based on changes in land systems and the geological framework. Pilbara cells were frequently defined to include areas with likely sediment supply by individual river systems, incorporating whole deltas within broader cells.

Offshore boundaries for the Mid-West have one criterion per cell level corresponding to depths of -30m AHD for primary cells, -15m AHD for secondary cells and -5m AHD for tertiary cells.
The Vlamingh Region has multiple depth criteria for offshore boundaries at secondary and tertiary cell levels due to sheltering by continuous ridgelines of elongate reefs, large offshore islands, large sediment banks and basins.
Offshore boundaries of cells in the Pilbara Region are related to tidal reworking of sediment and waves, whereas waves are the primary process for cells in the Vlamingh Region. One consequence of this difference is offshore boundaries generally occur at shallower depths for the Pilbara Region in areas where tidal reworking and extreme waves provide the dominant environmental forcing.
The Vlamingh Region has multiple depth criteria for offshore boundaries at secondary and tertiary cell levels due to sheltering by continuous ridgelines of elongate reefs, large offshore islands within primary cell offshore boundaries, large sediment banks and basins.
Marine sections of the alongshore boundaries were mapped as orthogonal to the coast in the Mid-West Region where limited bathymetric information was available, with more detailed bathymetry available for the Vlamingh Region. Mapping the toe of Holocene sediment banks in the Vlamingh Region is not included for the Mid-West Region.
Marine sections of the alongshore boundaries in the Vlamingh Region are fixed by toes of Holocene sediment banks, submerged rock outcrops and islands and follow lines of sediment transport convergence on banks and reefs. Marine sections cannot be easily resolved in the Pilbara Region due to extensive tidal reworking of sediments from multiple rivers across the broad nearshore area, combined with limited bathymetric information. Marine sections were often not orthogonal to the coast, but were skewed in the direction of the dominant current or wave forcing following high points in the bathymetry or ridge lines of islands.

The Vlamingh Region is the most densely populated area of the Western Australian coast with extensive coastal modifications. Hence more criteria for onshore boundaries and the terrestrial section of alongshore boundaries are related to engineering works.
The Vlamingh and Pilbara coasts have been modified in densely populated or industrialised areas. The physical extent of the engineered structures and reclaimed land in the Pilbara tends to not extend beyond the area of the majority of tidal reworking of riverine sediments. Therefore engineering works tend to be excluded as criteria for onshore boundaries and terrestrial sections of alongshore boundaries in the Pilbara.
Natural onshore boundaries of cells in the Vlamingh Region are mainly the landward extent of Holocene land systems. Two exceptions are included for the Mid-West Region to ensure exclusion of dunes without a connection to the coast and inclusion of dunes abutting rocky topography to landward, such as colluvial foot slopes and cliffs.
Natural onshore boundaries for primary cells in the Pilbara Region are linked to elevation contours for the extensive systems of outwash plains, with Holocene land systems used in the Vlamingh Region. Onshore boundaries for secondary and tertiary cell scales in the Pilbara Region relate to the landward extent of supratidal landforms and inter-tidal landforms respectively, excluding the presence of dunes, cliffs and engineered coasts.
Terrestrial sections of the alongshore boundaries also include discontinuities in large mobile dunes or narrow dune barriers for the Mid-West Region.
Terrestrial sections of the alongshore boundaries are defined in the Vlamingh Region by discontinuities in dune barriers and large landforms, or following the centerline of an engineered structure. The terrestrial sections cannot easily be resolved in the Pilbara Region due to extensive marine and fluvial interactions at multiple scales over the low-lying topography. Most frequently the boundary was mapped to ridgelines and connecting high points that separate basins.
Table C.1: Comparison of cell criteria for the Vlamingh, Mid-West and Pilbara Regions The same criteria apply for Mid-West and Northampton Regions. All reference to Mid-West Region should be read as Mid-West and Northampton Regions.
