Objectifs
1. To identify, delineate, map and to monitor the various waterlogged areas, with the help of visual image interpretation technique, in remotely sensed multispectral, multiseasonal and multitemporal images from the satellite viz., Landsat MSS/TM and IRS-1A. 2. To make a detailed study of waterlogged areas at village level by superimposing the interpreted data on the cadestral map of ¥ I taluka with village boundaries ait the scale of 1:250,000 and 3. To find out the accuracy level of remote sensing technique in delineating waterlogged land by carrying out a detailed ground truth survey of the study area to correlate^ the satellite informa t ion. Uft&k 4. To study the degree of deterioration of land in the area by mapping the vegetational status by using multiseasonal and multidate images. 5. To attempt the improvement in the presentation of results by various digital analysis using the LISS-II CCT data. To study the feasibility of IRS spectral bands to generate different indices, \/ and band ratios, for improving the interpretation of waterlogged areas. „ 6. To find the by carrying out impact of various phytosociological waterlogged soils study of the area. 7. To attempt to grow crops either which requires less application of water, to prevent the further degradation of soil or which could tolerant under waterlogging condition and 8. To ameliorate the waterlogging effect on crop by improving the availability of the nutrient by the application of biological and chemical treatments to the plants growing under waterlogging condition. 9. To recommend the possibilities of remedial measures to be taken for the proper management of the land on existing conditionfor reclamation and improvement of affected soils as well as conservation of non-affected areas.
