An attempt made to develop water resource for micro watershed of Visakhapatnam Urban Area. The study area extends from 17° 47’ 02’’ N to 17° 48’ 38’’ N latitudes and 83° 11’ 51’’ E to 83° 14’ 45’’ E longitudes, covering an aerial extent of 9.18 km2. A detailed examination of the existing three tanks in the study area is carried out using both spatial technology and ground based observations. The alteration of the terrain topography is studied from the survey of India toposheets and Total Station survey conducted in the study area. The 3-Dimensional terrain model is generated and the drainage network is simulated to study its interaction with the results of the change detection analysis. For the quantification of surface water bodies, Total Station survey is carried out for the tanks. Geophysical explorations are carried out, which identifies the thicknesses of top soil, weathered rock, fractured rock, hard fractured rock and hard rock formations, to assess the volume of the groundwater that can be stored in the aquifer system.
