Sedimentation measurements are used for calculation of dead volume storage capacity of dams at planning stage of dam projects. Calculating the sedimentation volume less than actual capacity causes operation-maintenance problems at water projects at engineering technics, while calculating the sedimentation volume more than actual capacity increases cost of water projects. Sediment accumulation in reservoirs decreases water storage capacity of dams in river basins, therefore it is essential to evaluate reservoir operation studies with sedimentation effects.
Berdan Dam is located in Mersin City, 6 km northeast of Tarsus in the southern part of Turkey, and constructed with purposes of irrigation, drinking water supply, flood control and energy on Berdan River. Berdan Dam was constructed in 1984 and it is operational since then.
The aim of this study is to estimate the amount of accumulated sediment in Berdan Reservoir by using Geographic Information Systems (GIS) to evaluate the water resources planning and management activities of Berdan Dam. In this study, analysis of sediment accumulation in Berdan Dam Reservoir is studied comparing the map of reservoir area with the hydrograhic map prepared in the year 2003 by using geographic information system technology. As a result, it is experienced that there is a 32% reservoir storage volume loss at minimum reservoir operation elevation, 12% reservoir storage volume loss at normal reservoir operation elevation and 4% reservoir storage volume loss at maximum reservoir operation elevation before the year 2003.
