Modeling and Management of Existing Watershed by using QGIS

Abstract

In this project we have made an effort to be acquainted with the aspect of ‘Watershed Management and Development’ using Geographical Information System. As there’s continuous increase in population and continuous degradation of environment. Also India is facing scarcity of water. Therefore watershed development is most suitable choice for development of rural areas. The main aim of this project is that the all of these engineering knowledge like GIS we’ve learned and apply it to different rural areas and lift economy as well as to improve the lifestyle of village people. GIS is computer based information management system which collects and stores specially reference multivariate (involving number of attributes or parameters) and multidate data. The name implies that the system deals with geographical space on the earth and its features. We have prepared the various layers like Gambian bund, cement nala bund, loose boulder structures, and percolation. We fix the position of those watershed harvesting structures according to their suitability. Also we show different contributory areas and we calculate runoff from each of the outlet. The above mention work is carried out in QGIS 2.18
