Watershed Management Planning Using Remote Sensing and GIS

This book is useful for adoption of soil and water conservation measures for application of Remote Sensing and GIS techniques for generation of development plans for the watershed area in consonance with the production potential and limitations of terrain resources and for assessing the impact of the measures undertaken before their implementation in the field. The survey can be done either by manually or by using remote sensing and GIS for the selected sub watershed (5G1C5e). The sub watershed of 16940 ha comprising of 23 micro watersheds falling in Junagadh district of Gujarat state (India) was identified and considered for the study purpose. The thematic maps were prepared using the Remote Sensing images, soil maps and reports prepared by NBSS & LUP. All these maps were digitized in the ARCVIEW module of ARC/INFO GIS software. The Soil Conservation Service Curve Number (CN) method is used for computing the runoff. In the present study, soil loss is predicted employing USLE method and an integrated analysis in GIS is carried out for Soil Conservation and for delineation suitable conservation unit. Satellites and other collateral data are used .
