GEO-SPATIAL TECHNIQUES FOR STRATEGICAL PLANNING IN WATER RESOURCES MANAGEMENT AT SURENDRANAGAR

Water Resources Engineering

Natural resources are important for development of any country and water is one of the precious natural resources as well as very complex to manage at the same time. In Gujarat many region are semi-arid region. Surendranagar region is the one of Semi- arid region which is located in Gujarat and facing problem related to water. This study aimed for sustainable management of water resources by the strategic planning and management. Models have been established in past for studying complex hydrological parameters. Resources assessment in Surendranagar region was accomplished by using remote sensing technique and GIS based Soil and Water Assessment Tool (ArcSWAT) was used for Runoff estimation. Land use and land cover changes also affect the runoff and essential input parameter in model. Hence it is important to detect the land use changes. Land use and land cover for the years 1993,1998,2005,2009 and 2015 were obtained through processing of satellite imaginary LISS-III (IRS) and TM (LANDSAT) sensors with spatial resolution of 23.5m and 30 m respectively in ArcGis 10.2 software using supervised classification technique. Geographic information system is essential for mapping of land use. Eight major land use parameters are taken for this study area are water body, vegetation, open land, waste land, sandy, aquatic vegetation, agricultural field, urban. Various parameters CARTOSAT-1 Digital Elevation Model (DEM), Land use, soil data and temporal data such as precipitation, temperature, wind speed, relative humidity was used as a input parameter in model. Analysis exposed that evapotranspiration losses are high because of high percentage of vegetation cover.
