Stream frequency is for every 5.14km 2. Drainage density is for every 1.92 km 3. The area is all most 50% black soil in valley and Red lateritic soil in ridges there fore there is a lot of infiltration of rain water and stream frequency is less. 4. Because of more infiltration in ridges the drainage density is also less.

Study area of Bagojikoppa and Mellikeri -126 ha Yield of the bores wells increased to 2 times irrigated area and 2 bore wells were over flowing 1bore well at chikkopa (water supply) and another bore well not fitted with motor because there was no water during drilling 2004 Monitoring of Bore wells:- Going on. One we found the irrigation area is increased compare to 2004 ie as per our data 100 ha now it is increased to double. No of bore wells-99 As on 2004 As on 2008 Functional 69 99 Not functional 30 o Chikkoppa
