Abstract:
The present study was conducted to investigate the site suitability of soil and water conservation in Gundlakamma Subbasin. The Gundlakamma subbasin is predominantly agricultural based and Gundlakamma is a seasonal river. Hence, planning of conservation measures to conserve water and soil resources taking hydrological planning unit as watershed is considered to be effective. Optimum utilization of natural resources like land, water, soil, vegetation, resources conservation measures and integrated development of the area along with the improvement in quality of lives of people are the main objective of watershed management program. In this study an attempt has been made for selection of the most suitable sites for water and soil conservation structures in Gundlakamma Subbasin of Prakasam district in Andhra Pradesh, India using Arc GIS. Delineation of the catchment area is carried out after georeferencing them. The IRS LISS-III satellite imagery used for LULC classes have been derived from it. A soil map is obtained from National Bureau of Soil Survey and Land use planning, Nagpur, India. The slope map and drainage maps are obtained from SRTM Digital Elevation Model. The various thematic maps such as LULC map, soil map, drainage map, slope map are laid over each other and optimal allocation of check dams are proposed for construction according to guidelines for selecting suitable site for water harvesting structures according to Integrated Mission for Sustainable Development (IMSD) Govt. of India. For suggesting soil conservation structures site locations considering slope parameter, slope was divided into four classes and accordingly structures are suggested for classes.
