Abstract

The study area, Bandu watershed of Purulia District extends from 23° 20′ N to 23° 47′ N’ and 86° 0′ Eto 86° 30′ E. The study area is under the upper catchment of Kasai river, Purulia district is a drought prone district of the West Bengal. Inspite of considerable amount of rainfall, due to heavy runoff the main problem of this area is scarcity of water as well as soil erosion. It has been accepted that for sustainable rural livelihood water and soil conservation is a must. The most suitable way to achieve this is micro-watershed development. But there is an acute shortage of technical manpower to handle such a huge volume of survey related work. For that reason, application of Remote Sensing and GIS has become a necessity. Moreover since fund is limited, watershed prioritization is highly required.
