Assessment of Waterlogged Areas in Kheda District, Gujarat, India using Remote Sensing

The introduction of canals has made increment in food grains but at the same time it has also led to the introduction of waterlogging and subsequent salinization, rendering large portions of Agricultural land unproductive. Remote Sensing and Geographical Information System (GIS) techniques can be extremely useful in accurate mapping and quantification of waterlogged area. Thus helping in preparing a sound database required for taking up various reclamative and preventive measures. In this study visual interpretation of satellite data, authenticated by ground truth was carried out for delineation of waterlogged areas in Kheda district. Visible temporal changes of land use/ land cover have been observed in the Kheda Mahi Right Bank Command Area affected by water logging and salinity. Supervised classification and NDVI calculations based on the 2014 LISS III data show that total 1844 ha area comes under wetland mapping , in which waterlogging is 12.81% of the total wetland area.
