Conclusion

In this report, the  emphasis was given on following points-

1) By using RS and GIS techniques, a microwatershed basic inventory was prepared in form of maps and text.

2) Six thematic layers of the study area such as aspect, slope, landuse, altitude, forest density, erosion class were generated using Satellite Digital Data.

3) On the basis of slope, landuse, altitude, forest density the study  area has been categorized into 4 erosion classes.

4) Total area of the micro watershed is 1844.37 ha., which is divided into 4 classes of erosion susceptibility-

a) Slight erosion- 57.58 %

b) Moderate erosion – 14.07 %

c) High Erosion -7.70 %

d) Very high Erosion – 21.11 %

5) Area covered under high and very high erosion classes should be considered on priority for management interventions to control erosion by applying soil conservation measures, gap filling etc.
