Watershed Characterization and Prioritization using Geomatics Technology for Natural Resources Management

Om Kashyap | Obaidullah Ehrar

Abstract: Watershed management is the process of formulating and carrying out a course of action involving manipulation of natural system of a watershed to achieve specified objectives. This implies the proper use of land and water resources of watershed for optimum production with minimum hazard to natural resources. Remote sensing and GIS techniques have emerged as powerful tools for watershed management programmes. The quantitative analysis of drainage system is an important aspect of characterization of watersheds. Morphometry is measurement and mathematical analysis of landforms. The present study is an attempt to evaluate the drainage morphometrics of Getalsud region using Remote Sensing and GIS approach. The low values of bifurcation ratio and drainage density suggest that the area has not been much affected by structural disturbances. The study reveals that the different geomorphic units in the study area i. e. Structural hills, Pediments, Valley fills, Pedi plains formed under the influence of permeable geology, are moderate to nearly level plains, with medium to low drainage density (
