4. Ahmedabad City Region Water Bodies and Topography LEGEND: Source: AUDA reports, A.M.C. website 1m interval 2 45km 1 3 0km N The topography of city shows that the land slopes towards South. The slope of the city is 1:750 (approx) The area under water-bodies is 38.54 km approx. 2.96% of the total area. The prime surface water body in Ahmedabad is the river Sabarmati, which flows from North to South and divides the city into two parts; East and West. It is not a perennial river. At Eastern side of the city, two minor rivers cross the region i.e. The Khari river and the Meshwa river. A number of ponds / lakes / water bodies are also present in the city. Due to rapid urbanization some lakes / water bodies have become extinct. About 36 lakes / water bodies have dried up in last 28 years.

5. PLAN SHOWING THE LOCATION OF THE VILLAGES AND THE CITY AS CORRESPONDING TO THE WATER BODIES Evolution of the City Relation of Water Bodies and the City VILLAGE SETTELEMENTS WATER BODIES N Every village had its own pond, which was the source of water. Size of pond varied from 20 ha to 80 ha depending on the size of the village. These ponds now remain dry during summer months. Important ponds in Ahmedabad are Kankaria filled with water throughout the year; and Chandola lake which remains dry even in monsoon.

The establishment of the first textile mill in 1861 was a landmark. With expansion of this industry, development began to spill over (beyond city walls) towards the north- east & south-east of walled city, but only on the Eastern side of the river. Construction of Ellis Bridge in 19 th century opened up the Western side for urban expansion – mainly Residential. Industrial development – Eastern side. Commercial development – Walled City. City extended beyond present municipal limits & crossed limits of AUDA on Western side. After 1982 growth was observed on main transportation routes, where agriculture was predominant.

The direction of slope is almost parallel along the flow of the river Sabarmati. (NE-SW) A few elevation points ‘tekras’ are observed in western Ahmedabad. Depression zone is present near the city of Mahemdabad. Open / vacant land occupies an area of 17.23 Sq.km. and is 3.6% of the total area of urban complex.
