Abstract: Water is one of the essential natural resources without water which we cannot exist on the earth surface. Thatipudi reservoir was constructed across river Ghosthani in year 1968 for storage of water used for drinking and irrigation purposes. The field survey carried on month of Feb 2014 and past data (of inflow, outflow and capacity of reservoir) collected from irrigation engineering department. Geo-environment factors like rainfall, temperature, topography, rock type and process of weathering in upstream area are causes for deposition of sediment in the reservoir and its effect on storage capacity of water were discussed. This is confirmed by using prismoidal formula, land use and land cover analysis by Arc GIS and ERDAS.
