A more detailed definition described the waterfront as the interface point where land and water meet, between approximately 200 to 300 meters from the water line and 1 to 2 km to the land site and also takes in land within 20 minutes walking distance. The waterfront area should have multiple features which incorporate each other and surrounded by structural and non structural objects to form a focal point.

HistoryThe earliest cities developed along river banks and sea ports such as Kolkata, Mumbai, London, Paris.In the later stage of development, waterfront areas began as commercial centers, transportation hubs and manufacturing centers, as a central focus for them.
DissertationRIVERFRONT
DEVELOPMENTRadhika Munshi| B.Arch

However, due to complex and multiple problems such as technology change, the historic preservation movement, increased environmental awareness and urban renewal, a dramatic change in waterfront areas was brought about and they became large spaces of unused property in the past thirty years or so.
The first waterfront development projects were started in North American cities, in particular Baltimore and Boston, in the 1960s..

Whereas the early examples of waterfront development primarily focused on leisure and retail; contemporary schemes have a broader scope. Many are set up with the aim to create attractive mixed urban environments that appeal to the imagination of people and persuade them to work there, to live there, or to visit these.

To develop Riverfront as Public Space• Establish a water’s edge that is continuous, publicly accessible and
magnificent • Create a network of public spaces that attract and invite both
localities and tourists to waterfront • Provide a wide-range of public spaces that foster culture and creativity
in our city • Ensure all public spaces adhere to a high environmental standard • Strengthen connections along the waterfront on both sides of the river • Develop strong link between existing communities and emerging
waterfront communities and spaces • Improve the aquatic habitat and water quality along the waterfront
and integrate them with river and stream improvements • Maintain a consistency in waterfront design elements in all public
spaces (i.e. Park benches and lamp posts) • Coordinate the water usage and supporting land base to maximize the
economic, recreational and environmental asset of Water bodies.

Ahmedabad and Sabarmati RiverThe city was founded in 1411 along the river banks. The river originates from the foothills of Aravalli ranges near Udaipur, Rajasthan, and flows downstream passing through Ahmedabad till Gulf of Cambay. The 109-km river runs across a stretch of about 11 km through Ahmedabad. It is this stretch that is developed as an ambitious urban renewal project

Need for Riverfront Development
The intensive uses took their toll on the river. • Untreated sewage flowed into the
river through storm water outfalls and dumping of industrial waste posed a major health and environmental hazard.
• The river bank settlements were disastrously prone to floods and lacked basic infrastructure facilities. Lacklustre development took shape along the riverfront.
Such conditions made the river inaccessible and it became a virtual divide between the two parts of the city.

Project ObjectivesThe project aims to reclaim the private river edge as a Public asset and restore the city’s relationship with its river. The Riverfront project presents a great opportunity to create a public edge to the river on the eastern and western sides of Ahmedabad.
The project is being developed by the Sabarmati Riverfront Development Corporation Ltd. (SRFDCL), a company wholly owned by the Ahmedabad Municipal Corporation.
The project was conceived in 1997, but it gained momentum only after 2001.

• 12000 hutments on both banks of the river occupying nearly 20% of critical project area.
• Unorganized Gujari Bazaar of more than 1200 vendors on the eastern bank and Court Litigation.
• Nearly 200 Dhobis using both the banks of the river for washing activities.
• Thoroughly polluted and contaminated Sabarmati through 38 storm water outlets. Dissertation
RIVERFRONT DEVELOPMENT
Radhika Munshi| B.Arch IV
Undertaking the ObjectivesEnvironmental ImprovementStrategies for overall environmental improvement have been formulated to achieve the following objectives:
• Reduction in Erosion and Flood
• Sewage Diversion
• Water Retention and Recharge
DissertationRIVERFRONT
DEVELOPMENTRadhika Munshi| B.Arch

Reduction in erosion and flood An optimal width of 263 meters for the water way has been selected and implemented. Both banks of the river have diaphragm walls built into the riverbed at a depth of more than 10m, and retaining walls which protect low-lying areas from periodic flooding and prevent erosion of the river banks.
DissertationRIVERFRONT
DEVELOPMENTRadhika Munshi| B.Arch

To stop the pollution of the river from the storm water outfalls and industrial effluents, an integrated storm water and sewage system with interceptor sewers has been implemented. These interceptor lines have been installed along both banks of the river capturing 38 sewage discharge points and routing the sewage with new pumping stations in the reclaimed banks. These lines carry untreated sewage to the recently augmented sewage treatment plants south of Vasna Barrage. Dissertation

Vasna Barrage downstream of Ahmedabad enables water to be retained the river
A more sustainable alternative is undergoing planning to use treated water from the sewage treatment plants to replenish the river. Hence, the traditionally monsoon-fed Sabarmati shall be able to hold and replenish water year-round. Water retention in the river enables recreational activities as well as groundwater recharge.

Conceptual map highlighting the use of treated water from sewage treatment plants to replenish the river
• The reduction of the riverbed from a variable width of 600-300 m to a fix width of 263 m, thus reclaiming 185 ha of land.
• The construction of RCC diaphragm walls (10-20 m depth) and anchor slabs (10 m) to prevent the riverbanks from erosion. After the finishing the anchor slab is turned in the so-called lower promenade.
• The construction of interceptor sewers on both the riverbanks able to prevent the waste water to flow directly into the river and diverting it to the two sewage treatment plants of Vasna and Pirana.
• The construction of RCC retaining walls (2.5 - 9 m) to protect the city from flooding. The height of the walls is determined by the 100-year flood level. An upper promenade is created on top of the retaining walls
