Suitable Site Detection for Groundwater Recharge in Parts of Shambhavi- Pavanje River Basin

The present study is the result of the research work carried out by generating the thematic maps based on satellite images and integrating the maps in a GIS environment, to suggest suitable locations/structures for artificial recharging of groundwater aquifers. Remote sensing (RS) data provides synoptic view, repetitive coverage and multispectral information, can be used successfully to generate different thematic maps. The study area covers about 355sq. km, which includes part of Shambhavi and Pavanje River basins of Mangalore, Karnataka. The area lies between 13000 and 13008 North latitude and 74045 and 750 00 East longitudes. SOI topographical map, satellite images of IRS-IC LISS III data, and Google images were used in the present study. ERDAS 2013 and Arc Map 10 softwares have been used to generate and integrate various thematic maps. Structures like nala bunds, check dams are suggested for recharging aquifers.
