e) Highly dissected plateau: This landscape unit is dominant 
in the northern hilly terrain and occupies about 30% of the total 
geographical area of the basin. The lands of this unit are 
severely dissected by the Dudhana, Purna, Karpara and their 
tributaries giving rise to a terrain consisting of flat-topped 
ridges and steep scarps. This unit has elevation range of 450 to 
560 m above msl. Morphometric attributes of the highly 
dissected plateau include steep slopes (> 10%), rapid runoff,

basin in Jintur Tahsil are part of hills along northern margins of 
Buldana-Ajanta plateau. The average elevation of these hill 
ranges is about 530 m above msl. They occupy about 4% of 
total geographical area. The hilltops have heights ranging from 
542 m above msl (in the west) to 488 m above msl (in the east). 
Apart from these, there are several isolated barren hills 
scattered over the plains within elevation range of 420 to 560 m 
above msl. These hills in the area have steep gradient (>15°), 
high drainage density (3 to 3.5 km/km?), high stream frequency 
(4 to 4.5 streams/km?), high relative relief (68%) and are 
characterised by rapid runoff. 
The soil cover this geomorphic unit is very thin. The soils are 
rocky, clayey, non-calcareous and underlain by weathered 
basalts. The flow characteristics of the basalts can be easily 
identifiable in the hills. The hills are sometimes barren and at
