Planning, designing and construction of series of check dams for soil and water conservation in micro-watershed

Abstract

Planning, design and construction parameters of series of water harvesting structures were presented for 66.75 hectares in micro-watershed. Thematic maps were prepared for planning, design of various types of water harvesting structures in 1:5,000 scale on land use/land cover, soil with drainage status. The slope of the land varies from 0-5 per cent and slight, moderate and serve erosion classes were observed. The total volume of water storage is 61,200 m3 at cost of 6.75/1000 liters, which also be estimated to protect 1607 m3 of productive soil from flowing out of the area. The series of check dam is found suitable for retaining productive soil and also to help in conservation of moisture for horticulture land.
