The catchment area of the Sabarmati basin is 21,674 km2 (8,368 sq mi) out of which 4,124 km2 (1,592 sq mi) lies in Rajasthan State and the remaining 18,550 km2 (7,160 sq mi) in Gujarat. The basin is located in a semi-arid zone with rainfall ranging from 450 to 800 mm (18 to 31 in) in different parts of the basin. The river traverses three geomorphic zones: rocky uplands, middle alluvial plains, and lower estuarine zone.
The major tributaries are the Watrak, Wakal, Hathmati, Harnav, and Sei rivers. Average annual water availability in the Sabarmati basin is 308 m3 (10,900 cu ft) per capita, which is significantly lower than the national average of 1,545 m3 (54,600 cu ft) per capita.
The Sabarmati is a seasonal river whose flows are dominated by the monsoon, with little or no flows post-monsoon. An average flow of 33 m3 (1,200 cu ft) per second was measured at Ahmedabad during the period 1968-1979. Over the past century, the flood of August 1973 is considered to be the largest flood, when a flow of 14,150 m3 (500,000 cu ft) per second was measured at Dharoi.
There are several reservoirs on Sabarmati and its tributaries. The Dharoi dam is located on the main river. Hathmati dam, Harnav dam and Guhai dam are located on the tributaries meeting the main river upstream of Ahmedabad while Meshvo reservoir, Meshvo pick-up weir, Mazam dam and Watrak dam are located on tributaries meeting downstream. The Kalpasar is planned project in the Gulf of Khambhat.
