Abstract
The main objective of the study was to suggest corrective measures for improving the productivity of the wetland eco-system. The specific objectives of the study was to utilize RS and GIS technologies to map the natural drainage course in the wetland and its catchments area in addition to preparing geo-morphological and ground water prospective map to explore and utilize the sub-surface water potential for irrigation. Second, to prepare detailed land-use/land-cover maps on 1:25000 scale and infer the availability of natural resources. Third, to prepare an optimum land use plan on 1:25000 scale, delineation and prioritization of the twenty micro watersheds of the entire catchments area of the wetland from soil erosion perspective. The total watershed area contributing water to the wetland system is about 25561 ha. The core waterlogged area of the wetland ecosystem having an area of 1750 ha (6.84 %) covering five revenue villages. Three basic themes of land-use/land cover, geomorphology and drainage and slope & watershed prioritization had been prepared. Based on the weighted parameters of SBI, NDVI, slope and other watershed characteristics, twenty micro watersheds were analyzed which falls in the study area. This micro watersheds had been categorized as low priority (6390.75 ha), medium priority (2407.66 ha), high priority (4372.34 ha) and very high priority (12390.25 ha) area. Considering the three field parameters such as slope, circularity ratio and drainage density as well as two remote sensing parameters such as NDVI and SBI, priority for treatment of each of the twenty micro-watersheds was assigned
