摘要：Terrain environment parameters play a vital role in controlling groundwater movement: its recharge and discharge mechanisms. Many earlier studies have been conducted relating terrain parameters and groundwater condition using conventional methods and remote sensing techniques. This study, however, endeavors to spatially visualize the degree of fluctuation in the groundwater level of Ongur, a minor river basin in different terrain units under different seasons (monsoon and summer) for three historical periods of time using Geographic Information System (GIS) raster analysis.
