Physiography

Physiographically, the basin can be divided into hilly and plain regions. The hilly regions are in the upper part of the basin as well as in the lower middle reaches and are forested. The plain regions in between the hilly tracts and in the lower reaches are broad and fertile areas well suited for cultivation. The available information on soil survey conducted in the basin indicates that black soils are predominant in the basin. The coastal plains are composed of alluvial clays with a layer of black soil on top. The culturable area of the basin is about 5.9 M.ha which is 3% of the total culturable area of the basin.
