Abstract
Resourcesat-I data is to provide continuity in operational remote sensing with its enhanced capabilities in the field of land and water resources management. Using GIS tools and image processing techniques are to identify the morphological features and water resources of the Meghadrigedda watershed. The morphometric parameters such as linear aspects and aerial aspects of six sub-watersheds of the watershed were determined and are computed. The drainage pattern is mainly dendritic type. The six sub-watersheds are elongated in shape. The Meghadrigedda reservoir supplies around 8 million gallon/day of water to the needs of Visakhapatnam city for domestic and industrial purpose. Most of the water tanks of the area have been silted and subjected to unauthorized occupations. Twelve recharge pits were located to excavate silted water tanks. To improve the ground water levels, thirteen suitable sites were identified for the construction of check dams in the Meghadrigedda watershed.
