Abstract

Water logging problem occurring in the command area of Mahi Right Bank Canal (MRBC) of Kadana dam has been evaluated using remote sensing and Geographical Information Systems (GIS). Various thematic maps have been prepared such as topography, geohydrology, soil, land use, Digital Elevation Model (DEM) and synthesised with the ground water and surface water and collated with irrigation data in GIS environment Major part of MRBC command area is occupied by Alluvium of Sabarmati and Mahi River and most part of the area is flat. Appreciable rise in the sub-soil water level has been observed since 1980 that is after starting irrigation through canal network of MRBC. Now major part of the Kheda district is either affected by water logging and salinization or presently under critical condition requiring immediate remedial measures and suitable management plan. Three talukas of Kheda district namely Matar, Mahudha and Kapadvanj are almost water logged and remaining under critical stage except part of Balasinor and Mehmedabad where water table is still in safe zone. Flat topography (0 to 1° slope), inadequate surface and sub-surface drainage, poor maintenance of existing drainage system, over irrigation and cultivation of more water intensive crops after the operation of canal network are some of major causes of water logging in the area.
