Sabarmati Basin

Sabarmati Basin extends over an area of 21,674 km² which is nearly o.7% of total geographical area of the country.

Sabarmati river rises from Aravalli bills in Rajasthan at an elevation of about 762 m and flows for about 371 km before outfalling into the Arabian Sea through the Gulf of Cambay. The principal tributaries of Sabarmati are the Sei, the Wakal, the Harnav, the Hathmathi and the Wartak.

The important soil types found in the basin are black, alluvial and sandy soils.

An average annual surface water potential of 3.8 km3 has been assessed in this basin. Out of this, 1.9 km3 is utilisable water. Culturable area in the basin is about 1.6 Million ha, which is 0.8% of the total culturable area of the country.

Present use of surface water in the basin is 1.8 km3. Live storage capacity in the basin has increased significantly since independence. From just about 0.1 km3 in the third plan period, the total live storage capacity of the completed projects has increased to 1.4 km3. In addition, a storage quantity of over 0.1 km3 would be created on completion of projects under construction. An additional storage to the tune of over 0.1 km3 would become available on execution of projects under consideration.
