The river traverses three geomorphic zones rocky highlands, midmost alluvial plains, and lower estuarine region.

The significant branches are the Watrak, Wakal, Hathmati, Harnav, and Sei rivers. The average yearly water availability in the Sabarmati basin is 308 cubic meters ( 10,900 cu ft) per capita, which is significantly less than the national average of 1,545 cubic meters ( 54,600 cu ft) per capita.

The Sabarmati is a seasonal river whose streams are conquered by rainfall, with little or no flows post-monsoon. An average inflow of 33 cubic meters ( 1,200 cu ft) per second was scaled at Ahmedabad during the period 1968 – 1979. Over the past century, the deluge of August 1973 is regarded to be the largest flood, when an inflow of 14,150 cubic meters (500,000 cu ft) per second was spanned at Dharoi.
