Recognizing Outlet Points Description on Watershed in Ottanchatram Taluk by GIS

Abstract

Groundwater becomes mandatory in day-to-day routine life without any limitation; we were using groundwater for irrigation, domestic and industrial needs. Unlimited groundwater pumping has decreased groundwater levels in some areas of the review region. The purpose of this document is to present the description of the outlet points of the river basin. This document explains the method of revealing the DEM-based basin outlet point. With Geographic Information System (GIS) support, river boundary basins and drainage areas are discharged into an area where a pumping station can be installed in the Ottanchatram district of Dindigul, Tamilnadu. To provide easy flow of wastewater to a treatment plant or river basin. Using an environmental GIS hydrology module, the watersheds for Ottanchatram taluk have been illustrated. The result of this experiment indicates that this method can effectively solve the problem of parallel routes and the main channel out of its natural position. In flat, mountain and landscape areas this method can reveal pour point by using DEM.
