Management Approach for Integrated Development of a Watershed

Abstract

Watershed is an area that has common drainage. In other words, it is a manageable hydrological unit. Since water is the most scarce resource of rainfed areas, it goes waste in the rainy season due to seepage and at the same time cause heavy damage to fertile land by soil erosion. In India, 80 percent of total rains in a year are seen in the month s of Jul y to September and the same percent of rain water is lost in run-off. The watershed unit provides an opportunity to harvest rain water falling in the area of its ridge lines and manage it for irrigation purpose. It also allow excess water to flow through a common drainage, thereby, avoiding excessive soil erosion
