Watershed management using remote sensing and Gis of maheshwaram watershed

Abstract

Conservation of integrated watershed management essential resources plays an active role in reduction of unfavorable effects like soil erosion, production of food determining the exact water potential zones etc. Land potential is the main basis of managing watershed. Watershed management studies demand is increasing in the recent years. The study is not limited to drought prone areas, but also in humid and semi humid areas in order to maintain the survival of the crops in critical stages. The main objective of the current study area is management of Maheshwaram Watershed based on the rainfall data. In the study area the rainfall data is collected for the 10 years span (2006-2015) from ARI (Agricultural Research Institute) from Rajendra Nagar Hyderabad. Topographic maps are collected from Survey of India in order to prepare base map, digital elevation model (DEM), contour map, drainage map. The Second main objective of the study area is approximation on annual and monthly run-off by using rainfall data. Further Base map, DEM(Digital Elevation Model), contour map, drainage map, slope map, land use and Land cover map, TIN(Triangulated Irregular Network) maps were generated by Survey of India toposheet maps to prepare maps by using ArcGIS Software. Analysis of the study helps the decision makers to provide sustainable planning of the environment and economy in the future.
