    Abstract

    Demand for groundwater resources is increasing from time to time due to the insufficient surface water supply to meet the growing demand. The increasing demand for water resources is caused by many factors such as population increase, urbanization and farming activities. Therefore the study to determine groundwater availability is quiet difficult due to the existence of multiple contributing factors. This study was conducted based on the parameters that contribute to the availability of groundwater potential. There are nine parameters used in this study i.e. lineament, land-use, rainfall, lithology, topography, slope, drainage, soil types and the ratio of sand and clay. These parameters are collected, processed, analyzed, integrated and modeled by using the remote sensing and Geographic Information Systems (GIS) techniques to create all the related thematic maps. Two software that have been used in this study are ERDAS IMAGINE 8.4 and ILWIS 3.3. The different ranks and weightages were assigned to respective different parameters with reference to groundwater and generated individual layers. Then, all the individual thematic layers were integrated; the weightages of each parameter added and finally the area has been divided into different groundwater potential zones using the Index Overlay and Analytical Hierarchy Process (AHP) method. The potential map was further classified into five categories or zones namely very high, high, moderate, low and very low.
