摘要
Remote sensing and geographic information system (GIS) have become one of the leading tools in the field of hydrogeological science, which helps in assessing, monitoring and conserving groundwater resources. In this paper, integrated remote sensing, GIS and fieldwork techniques were combined to delineate the groundwater potential zones map of Devak and Rui watersheds of Jammu and Kashmir. Remote sensing data were used to prepare hydrogeomorphology, drainage density and land use/land cover maps. The advanced space borne thermal emission and reflection (ASTER) digital elevation model (DEM) data was used for preparing the slope map. Pumping test data were used to prepare discharge, specific capacity, static water level, transmissivity and hydraulic conductivity maps. Well inventory data were collected to prepare the pre-monsoon water table, post-monsoon water table, static water level and fluctuation maps. All the thematic maps pertaining to chosen parameters were converted to raster data. The raster maps of these parameters were assigned an appropriate theme weight and class score. All thematic layers were integrated using the weighted index overlay analysis (WIOA) method in the GIS environment to determine groundwater potential map. The ground water prospects zones were depicted in five categories excellent, good, moderate, low and runoff zone. The results revealed that excellent zone covers 13.5 %, good zone 22.7 %, moderate zone 15.8 %, low zone 18.5 %, and runoff zone covers 29.5 % of the total study area. The result depicts the groundwater potential zones found to be helpful in better planning and management of groundwater resources in the study area.
