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