Abstract

The present study emphasizes on the integrated remote sensing and GIS approach for delineation of the groundwater potential zone in Shimla city area, Himachal Pradesh (India) using multi-criteria decision making techniques (knowledge based and analytic hierarchy process). The multiple thematic layers of influencing parameters viz. land use/ land cover, slope, geology, drainage density, geomorphology, lineament density, rainfall and soil were prepared in GIS environment using satellite images of IRS P6 LISS IV, ASTER GDEM and climatic data. Weightages were assigned to the each parameter according to their relative importance as per expert’s opinion and research studies of the region. Further, the analytical hierarchy process was applied to these parameters for demarcation of groundwater potential zones. Through applying above models five areas having very low, low, moderate, good, and very good groundwater potential zones were distinguished. The results indicated that 7% of the area had (very good-good), 11% (moderate), 50% (low) and 32% (very low) groundwater potential zones using knowledge based technique whereas 7% of the area had (very good-good), 12% (moderate), 47% (low) and 34% (very low) groundwater potential zones using analytical hierarchy process technique. The overall result shows that there was very minor change in the groundwater potentiality using both the techniques.
