Özet
Future precipitation patterns are expected to shift toward sudden, intense rainfall events. Therefore, existing water reserves must be adapted, and new management systems developed to address these changing conditions. Galleries can serve a dual role by diverting potentially threatening floodwater to delay its arrival at the dam while also contributing to groundwater recharge through infiltration. This study focuses on 25-year return period floods at Yuvacık Dam, Turkey. Water levels at the reservoir inlet were raised via a regulating structure, allowing the gravitational diversion of floodwater into galleries. Approximately 2.2 hm³ of floodwater was diverted; 1.8 hm³ was directed to galleries, and 0.4 hm³ infiltrated into groundwater. Changes in peak discharge and flood duration before and after diversion were analyzed using a MATLAB-based flood routing model. Sensitivity analyses were conducted to examine the effects of gallery diameter, slope, and permeability coefficient on infiltration performance. Results indicate a 16% reduction in peak flood discharge. The proposed system is expected to enhance both flood safety and water resource management by enabling controlled diversion and partial infiltration of potentially wasteful floodwaters.
