Abstract

An attempt was taken to establish the relationship between morphometric variables and hydrologic parameters through watershed prioritization. Samshe hole watershed of Chikkamagalore district was selected as the study area. Overexploitation of Groundwater resource caused an extensive scarcity of water in this region. The major source of drinking water is from Groundwater resource. To control the overexploitation of Groundwater resource, it is necessary to practice an efficient management of watershed development. The research effectively focused on developing a methodology to analyze watershed condition using microwatershed prioritization. Remote sensing and GIS tools were used in order to achieve the expected results. The secondary data, SoI toposheet was used to generate base map of the study area and used to extract drainage patterns and contour informations.Hydrogeomorphological map was created to analyze the influence of hydrological regime through morphometry. Selected Linear, Aerial and Relief parameters were calculated in this research. Thematic layer integration was applied to prepare prioritization map in GIS environment. Three categories of groundwater prospects were characterized such as poor, good and excellent micro-watersheds in this study area. The study emphasized the integrated applications of micro-watershed prioritization to effectively manage groundwater resources through action plans.
