Abstract

Building a dam is one potential method for reducing flood episodes in middle Tapi, Maharashtra, India. The Analytic Hierarchy Process (AHP) was chosen in conjunction with Geographic Information System (GIS) as the method of Multi-Criteria Decision Making on picking dam site due to the difficulty of choosing a dam site. Finding an appropriate location to build dams could be the initial step for this goal. Water resources planners can now more easily determine the ideal placement for a dam thanks to the development of Remote Sensing (RS) and Geographic Information System (GIS) technology. The current study aimed to apply AHP technique with GIS for decision making in order to determine the best location for the dam. For a dam site suitability map, SRTM DEM was used to create a total of 10 spatial layers (elevation, slope, drainage density, rainfall, lulc, distance to river, road network density, geology, geomorphology, and soil). The weights of the thematic map layers were determined using the analytical hierarchy process (AHP) technique, which is one of the Multi-Criteria Decision Making (MCDM) techniques. Five categories of appropriateness, ranging from very high to very low suitability zones, are depicted on the overlaid map. The study gives decision-makers a practical and economical tool for locating places with high constraints (low acceptable site) and focusing on locations with fewer restrictions for a more suitable location for the construction of dams
