Investigation of Groundwater Potential Zone ...

Geospatial technology has been done to identify spatially the extents of highly suitable and moderately suitable areas for groundwater demarcation. Several input parameters (land use, soil type, slope, geology, geomorphology, and lineament) used to maps Groundwater potential assessment. Each thematic map has been reclassified into five classes. Suitable weightages have been given to each class with respect to its groundwater potential influences. Area of all raster formats of all parameters were calculated by GIS environment. All the weighted input parameters have been overlaid using “Weighted Overlay Analysis” tool in ArcGIS 10.3 platform. The results showed that 8.26Km2, 441.74 Km2, 812.86 Km2, 198.01 Km2and 80.57 Km2of the study area fall in “Highly suitable, High, suitable, Medium suitable, Low suitable and Very Low suitable” category of groundwater potential respectively.
