RS/GIS Technology for Groundwater Potentiality Assessment Hydrological analysis

This research work used remote sensing (RS) and geographical information system (GIS) technology for hydrological analysis to delineates groundwater potentiality assessment for growing population, irrigation and industrial development in Kalmykia, Russia. Various thematic layers wear used along with existing maps and field data to know groundwater potentiality. Weights were assigned to all factors according to their effectiveness, sensitivity and relevance to ground water potentiality. Furthermore the resulting map has been classified into five classes, named very high, high, moderate, low and very low based on hydro-geomorphological condition. The results provide significant information and can be use by local authorities for groundwater exploitation and management.
