An Integrated Approach of Remote Sensing and GIS for Surface Water Conservation and Management Plan, Madhya Pradesh, India.

Abstract

Land use/land cover mapping plays an important role for surface water conservation and management plan. The study of land use/land cover mapping prioritizes locations for suggesting appropriate recharge structures and effects of land use/land cover (LU/LC) changes on surface water storage. Main objective of the study is surface water conservation and management via multi-spectral information resulting from remotely sensed data to increase the irrigation. With the use of remote sensing/GIS data and techniques in current study, catchment area, gross command area, minimum draw down level, full reservoir level, length of dam and height of the dam have been delineated. These parameters are required for feasibility study and detailed project report preparation for dam construction. The land use/land cover statistics of submerged area help to identify the cultivated land, fallow land, open/waste land, forest, settlement and surface water bodies of study area. Identification of fracture/lineaments, creation of digital elevation model, digital terrain model and 1 meter interval contours are prerequisites for undertaking surface water conservation and management in basaltic terrain. Command area of the proposed scheme lies in Beda sub-basin, which is a tributary of the Narmada river. This study proves that implementation of Nimkheda scheme will increase the cultivated area under irrigation, facilitate the farmers for multi season cropping and help in improving their economic condition.
