CHAPTER 2
STUDY AREA: CUDDALORE
2.1 INTRODUCTION
Tamil Nadu, the southernmost state of the Indian peninsula, spread
over 1,30,058 km2, lies between 80 0 0 0
Tamil Nadu has 32 districts of which 13 districts are located along the coast.
Cuddalore district (figure 2.1) is situated about 160 kms south of Chennai, the
state capital. The area of the district is 3706 km2. The headquarters of the
Cuddalore district is Cuddalore (11044' 45" N and 79045'56" E), a large
industrial town which has experienced coastal development at a rapid rate.
Cuddalore district is bounded on the north by the Villupuram district and the
Union territory of Puducherry, on the west by the Perambalur and Ariyalur
districts, on the south by the Nagapattinam, Thiruvarur and Thanjavur districts
and on the east by the Bay of Bengal.

The coastal stretch of Cuddalore extends from Gadilam estuary in the
north to Pichavaram mangroves in the south, a total length of 42 km along the
Bay of Bengal. The Bay of Bengal experiences severe tropical cyclones during
the northeast monsoon (October through December), and nearly 60 cyclonic
storms and SCS have been reported in the past century (Indian Meteorology
Department (IMD) eAtlas 2011). An added risk factor is that large parts of this
coastal zone are low-lying with a gentle slope, resulting in wide inundation
areas, thus increasing the vulnerability of the region (Murthy et al., 2006).
2.2 HISTORY
The district was ceded to the British in 1801. Until 1808, it consisted
of that part of the Mughal Subah of Arcot which lay to the south of the river
that the country around the Palar was in olden days covered by six forests which
were the abodes of six Rishis (saints). The history of the systematic
administration of the Land Revenue of erstwhile South Arcot District begins
with the acquisition from the Nawab in 1801, when the Nawab handed over the
Carnatic to the Company. Captain Graham, who was appointed to take charge of
the district lying between Palar and Portonovo rivers, became the first Collector
of South Arcot (South Arcot Gazetteer, 1961).
At that time, the district of South Arcot consisted of the 21 Taluks of
Arcot, Vellore, Thirupathur, Polur, Arani (the Jagir of that name) Wandiwash,
Chetpet, Thiruvannamalai, Gingee, Tindivanam, Valudavur, Villupuram,
Anniyur, Tirukoilur, Thiruvennainallur, Tiruvadi, Elavanasur, Kallakurichi,
Vridhachalam, Tittagudi and Bhuvanagiri but excluded the Fort St. David and
the territory of Pondicherry, both of which had been separately acquired and
![Page 3: CHAPTER 2 STUDY AREA: CUDDALORE 2.1 …shodhganga.inflibnet.ac.in/bitstream/10603/26469/7/07...of that part of the Mughal Subah of Arcot which lay to the south of the river that the](https://reader031.vdocument.in/reader031/viewer/2022021610/5cad4f9588c9933f078d06bf/html5/thumbnails/3.jpg)

administered separately. In April 1805, the then Taluk of Mannarkudi (now
known as Chidambaram) was added from Tiruchirapalli to this huge charge.
However in 1808, Arcot, Vellore, Thirupathur, Polur and Arani Jagir were
transferred to North Arcot and Wandiwash to Chengelput while the Fort St.
David and Pondicherry villages (which at different time had been under both,
the Collector and the commercial resident at Cuddalore) were annexed with the
District. In 1816, Pondicherry was finally restored to the French and erstwhile
South Arcot assumed practically its position. Cuddalore was District
Headquarters for South Arcot District for more than a century (South Arcot
Gazetteer, 1961). The present Cuddalore District was formed on 30.9.1993 by
bifurcation of the South Arcot district into two viz., Cuddalore and Villupuram.

2.6 TOPOGRAPHY, SOIL AND AGRO-CLIMATE ZONES
The district, for the most part, is a flat plain, sloping gently from
north to south and from west to east, towards the sea. The only hill in the district
is the Mount Capper hill near Cuddalore. The Mount Capper plateau, just west
of C
south-south-westwards to near Shrimushnam (figure 2.3). Mount Capper is the
only part which can be termed as a prominent feature in the landscape and even
this is only about a hundred feet above mean sea level. For the rest, the course of
the formation, where it has not been cut away by the rivers which pass through
it, may be traced by the red soil to which it gives rise and which is some of the
most unfertile in the district (South Arcot District Gazetteer -1961).
The geomorphology of the Cuddalore coastal stretch includes the
coastal plain with an average width of 6 km. Its coastal landforms include
strand-lines, raised beaches, sand dunes, mangrove swamps and tidal flats with
predominantly sandy beaches on the northern side and mangrove swamps to the
south. The coastal towns of Cuddalore in the North and Porto Novo
(Parangipettai) in the South are the most densely populated along this region.
The soils of the district can be divided into three main classes namely,
the black of regur, the red ferruginous and the Arenaceous. The black soil
prevails largely in the Chidambaram, Vriddhachalam and Cuddalore Taluks.
The Arenaceous occurs chiefly near the coast in the Taluks of Chidambaram and
Cuddalore. Black clay is the most fertile kind of soil, the loam is the next best
and the red sand & Arenaceous soils are the poorest. The total red soil comprises

2.7 METEOROLOGY
The district receives total rainfall of 1104 mm. It includes both the
south west (373 mm) and north east (731 mm) monsoons. The maximum
recorded temperature of the district is 36.80 C while minimum temperature is
19.90 C. The season-wise rainfall for the last decade is given in table 2.2. North
east monsoon is the wettest period of the year when cyclonic activities in the
Bay of Bengal bring in the rainfall. An analysis of the annual cyclones (C) and
Severe Cyclonic Storms (SCS) in the Bay of Bengal region given in IMD e-
Atlas, clearly indicates that although the frequency of cyclones has decreased in
the recent years (after 1980s) there is a marginal increase in the occurrence of
SCS (figure 2.5), which in turn implies the increased magnitude.

2.10 HYDRAULICS AND HYDRODYNAMICS
Tamil Nadu has seventeen major river basins as shown in figure 2.7.
All the rivers of the state are seasonal in nature. Tamil Nadu is water stressed
state where almost full irrigation potential of available ground and surface
irrigation water has been exploited.
Figure 2.7 Tamil Nadu River Basin Map (Source: IWS, TN SCRSA, WRO, PWD)
2.10.1 Drainage Pattern
Cuddalore district is endowed with the following five river basins
(figure 2.8) from north to south 1) Pambai River Basin; 2) Pennaiyar river basin;

3) Gadilam river basin; 4) Vellar river basin; and 5) Cauvery- Coleroon river
basin.
Figure 2.8 Cuddalore River Basin Map Showing watersheds
Almost all the rivers of the district flow east into the Bay of Bengal.
The Ponnaiyar or the Pennar rises in the Chenna Kesava hill, east of Nandidurg
in Mysore, Karnataka State, travels eastwards and finally joins the sea about 5
kms north of Cuddalore town. The Malattar, which takes off from the right of
the Ponnaiyar in Villupuram district, divides itself into two branches just before
it leaves Thirukoilur Taluk (figure 2.8). Its southern and major branch joins the
Gadilam. The Gadilam rises in the eastern part of the Tirukkoyilur Taluk, enters
the Cuddalore district where the seasonal river Malattar comes and joins it on
the right, flows past Panruti (figure 2.8) and through Tiruvendipuram and
Cuddalore and joins the Bay of Bengal. The river suddenly turns to the south,
runs to the east of Cuddalore OT which stands on the edge of the backwater
formed at the junction of the mouths of the Gadilam & the Uppanar and flows
over a bar into the sea. Ordinarily the Gadilam is dependent on local rain and

during the floods; it receives a dangerously large supply from the Ponnaiyar
through the Malattar. It carries very fertile silt and has four Anicut across it
which help in irrigation. In ancient days it was called the Kedilam meaning a
as Garudanadi.
The Uppanar, or the Paravanar, takes its source in the Vriddhachalam
Taluk, flows eastwards along the boundary between the Cuddalore and the
Chidambaram Taluks and joins the Bay by the mouth of the Gadilam just to the
south of Cuddalore OT. It is largely a drainage channel for the land irrigated by
the Sethiyathope Anicut across the Vellar. Its water often backs up and floods
the land along its sides. The Kudivaiyar is a small stream in Cuddalore Taluk
which joins the Uppanar close to its mouth near the Bay.
The Vellar (White river) is formed about four miles west of
Thozhudur in the Vriddhachalam Taluk, by the junction of two rivers, namely,
the Vasishtanadi and Swetanadi which rise in the Salem district. Vellar flows
through the Vriddhachalam Taluk where it receives a considerable tributary, the
Manimuktanadi about four miles east of Shrimushnam, which is made up of the
Mani and the Mukta streams that drain the northern part of the eastern slopes of
mouth river) and the Mayuranadi
(Peacock river) that rise in the southern portion of the hills. These rivers have
cut for themselves deep clefts with often precipitous sides in the valleys, notably
in the Tumbe valley down which the Manimuktar flows. The confluence of the
Gomukhanadi and the Mayuranadi at Nallur is held to be holy and a picturesque
little temple has been built on an island at the spot. After it is joined by the
Manimuktar, the Vellar flows through the Chidambaram Taluk and joins the sea
immediately south of Porto Novo (Parangipettai). The Vellar receives little
supply from the south-west monsoon, but the north-east monsoon gives adequate
supply towards the latter part of the year. Its banks are often high and steep and

are affected by the tide for about seven or eight miles above its mouth at Porto
Novo (Parangipettai).
2.10.2 Irrigation and Ground Water
The sources of irrigation in this district are wells, tanks and canals.
Wells (open and tube well) are the major source of irrigation and cover 56
percent of the area. There are about 93,000 Tube Wells, 8,700 open wells, 6,525
PWD/minor irrigation tanks and about 860 other sources.

2.11. FISHERIES
Cuddalore District has high potential for marine as well as inland and
brackish water fisheries. The district has a coastline of 68 kms. Fish are plentiful
in the tanks. The marine fisheries provide a living for a large number of
persons. Pomfret, seer fish and mullet are among the better known kinds of fish
and the oysters of the Cuddalore backwaters enjoy a more than local fame. There
are 8104 ha of inland water resources, 5986 ha of major irrigation and long
![Page 19: CHAPTER 2 STUDY AREA: CUDDALORE 2.1 …shodhganga.inflibnet.ac.in/bitstream/10603/26469/7/07...of that part of the Mughal Subah of Arcot which lay to the south of the river that the](https://reader031.vdocument.in/reader031/viewer/2022021610/5cad4f9588c9933f078d06bf/html5/thumbnails/19.jpg)
70
seasonal tanks, 312 ha of Fish Farmers Development Agency (FFDA) tanks,
1,000 ha of derelict water and 806 hectare of Aquaculture farms.
45 marine fishermen villages are located in the district with total
marine fishermen population of 47,000 of which active fishermen are around
23,840. The total members in the marine fishermen cooperative societies are
15,133 and members of fisherwomen cooperative societies are 13,094. The
fishing fleet of Cuddalore District includes 606 mechanized boats, 1010
motorized country crafts and 5580 traditional crafts (Tamil Nadu Marine
Fisherfolk Census 2010). There are three fish landing centres for mechanized
boats in Cuddalore, Parangipettai and Mudasalodai. There are 28 Inland
Fishermen Cooperatives Societies with a total membership of 2600 fishermen
and 400 fisherwomen. In the inland sector, there are 15 fish rearing centres in
the private sector. There are 164 shrimp aqua farms with 366.41 hectare water
spread area. In the inland fish landings, Catla, Rohu, Mrigal, common carp,
silver carp and fresh water prawns are important.
2.12 GEOLOGY AND MINING
The general geological formation of the district is simple with
metamorphic rocks belonging to the gneiss family. Resting on these are the three
great groups of sedimentary rocks belonging to different geological periods and
overlaying each other in regular succession from the coast on the east to the hills
on the west. The lowest of these groups is the fossil-bearing cretaceous
limestone around Pondicherry and Vriddhachalam. Above this comes a younger
form the Red hills near Pondicherry and the Mount Capper hills south-west of
Cuddalore. Uppermost are the alluvial beds of the deltas of rivers. There is
every reason to believe that this order of the strata has existed unaltered through
a long geological period; that in fact, since the beginning of the time when the
![Page 20: CHAPTER 2 STUDY AREA: CUDDALORE 2.1 …shodhganga.inflibnet.ac.in/bitstream/10603/26469/7/07...of that part of the Mughal Subah of Arcot which lay to the south of the river that the](https://reader031.vdocument.in/reader031/viewer/2022021610/5cad4f9588c9933f078d06bf/html5/thumbnails/20.jpg)
71
oldest of the sedimentary beds, these of cretaceous age, were deposited. No
disturbance of any magnitude has remodelled or effaced the main features of the
district (South Arcot Gazetteer, 1961).
Trap dykes are not common in the district. There is, however, a
regular assemblage of small basaltic trap dykes at Thozhudur where the NH-45
crosses the Vellar and a large dyke about eight kms long across the same river
about 6 kms west of Thozhudur. There is a good artesian basin in the district
occupying a few square kms around Neyveli, Aziznagar and Kavanur near
Vriddhachalam. There are apparently three or four distinct water bearing
horizons here, all in the Cuddalore sandstones and there are a number of flowing
wells in this area.
Gneiss, trap and sandstone are the main minerals of the district.
Gneiss is used for building purposes with excellent results especially in the
temples. Its susceptibility to fine carving is exemplified in the chains cut from it
which may be seen in the shrine at Srimushnam and the great temple at
Chidambaram. Trap is scarcely used for building purposes because of its
intractable hardness and inherent moisture absorbing quality. Sandstone is used
for building purposes as well as for making mortars, troughs, etc. Besides these
minerals, laterite occurs over a wide belt of country between Pondicherry and
Vriddhachalam (notably on Mount Capper), in the red soil tract around
Srimushnam and to the east of Vriddhachalam. It is largely used for building
purposes and road making.
There are a large number of clay deposits in the district. White clay
occurs in many places. It is exposed in the deep ravines below an overburden of
35 feet of sandstones and grits at Pannikappam, south of Panruti and just south
of the Gadilam river. It burns to a pale grey colour, it is refractory and its
shrinkage is high, being 40 percent. Lignite has been found to occur mainly in

2.13 STUDY AREA
The study area has been shown in figure 2.9 in which (a) is a map of
the entire Cuddalore District (42km coastline) and (b) is the site specific study
area (14km coastline) within the Cuddalore District used for delineating the
composite hazard line on a pilot scale and conducting the vulnerability mapping.
The coastal geomorphology of this region includes sandy beaches on the
northern and mangrove swamps on the southern stretch of the coast. The major
geomorphic features of this coastal stretch comprise of upland plain, flood plain,
deltaic plain and coastal plains. The coastal plain has a width of 6 km and
exhibits different geomorphic features, which include strandlines, raised
beaches, sand dunes, mangrove swamps and tidal flats. The coastal towns of
Cuddalore and the adjacent Porto Novo are also the most densely populated
along this coastal region.
The study area is spread over nine revenue villages and one town
panchayat. There are 19 fishing habitations along the coastline in the study area.
The study area starts just south of the Cuddalore O.T. SIPCOT industrial area
and has a major industrial establishment- Nagarjuna Oil Refinery. Fishing and
allied activities are the main source of livelihood in the area with minimum
extent under cultivation. The coastal belt earlier had good cashew and casurina
plantations which have been progressively diminishing to give way for other
activities.

The study area is highly prone to cyclones and flooding. Almost
every year the local population faces cyclonic storms and coastal inundation,
particularly during the monsoon between October and December. Further, it was
one of the worst affected areas due to tsunami that had occurred during 2004 in
which large scale human and cattle deaths and extensive damage to fishing
assets and houses were reported. This stretch of coast was selected as study area
due to greater risk exposure and the recurrent history of hazard and disaster with
significant extent of losses suffered by the population.
