| Özet |
| Reservoir sedimentation is a very serious problem in Turkey, as it is in many countries. Deposited sediment in reservoirs causes water storage capacity losses, thus reducing potential benefits that could be gained from hydropower generation, irrigation, water supply and flood control. Although the useful life of a reservoir is generally determined from the rate of dead storage capacity loss, the basin applications more than often have appeared to commission the farthest downstream ones of cascade planned projects first due to their higher internal rates of return. Hence, at design stage of such reservoirs, sediment yield estimations are based on the existing upstream conditions at that time as it is not known when the upstream dams will be constructed. This uncertainty can lead to enormous dead volume allocations to remain on the safe side in determining minimum operation levels and, hence, positioning intake structures. In this study, the inability to be used entire potential water storage capacity resulting from inappropriate basin management practices is presented with the example of Botan Creek. The results show that the total active storage of the farthest downstream three dams could be increased about up to 38.47%(337.85 hm3) according to optimization studies to be conducted. |
