Prioritization of Micro-watersheds in the Balekoppa Subwatershed based on Morphometric Analysis: A Geospatial Approach
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
Conservation and optimum usage of surface and subsurface water can be done by the development of watershed management. GIS and RS are very efficient in quantifying morphometric parameters and giving an idea about the geological and hydrological conditions of the area under consideration. In this regard Balekoppa sub-watershed is chosen for the prioritization of its micro-watersheds and to assess its erodibility and other critical problems and potential threats. The study area is located in the Sirsi taluk of Uttara Kannada district and covers an area of 58.94 sq. km. With the help of GIS the basic morphometric parameters are determined and the applied parameters are derived from the basic parameters. The study area is divided into fourteen micro-watersheds and these are prioritized based on morphometric analysis in a GIS platform. Based on the compound ranking of each micro-watershed prioritization is carried out and its erosional potentiality is analyzed. Based on the results obtained, three micro-watersheds fall under high priority, other three under medium and the remaining eight under low priority.
