description | Maintaining ecological flow is crucial for preserving healthy aquatic ecosystems. This study presents a novel approach to assess and secure ecological flow by linking fish growth scenarios with water budget analysis. Addressing the challenges of accurately predicting ecological flow requirements, especially in post-dam-construction scenarios, is a central focus. In the Gam River basin, we assess the compatibility of a target fish species with post-dam quantitative instream flow, confirming an appropriate 4 m3/s for Zacco platypus in the basin's water supply system. This determination, facilitated by the K-WEAP model, not only ensures water availability but also prevents the Gimcheon-Buhang Dam from falling below its dead storage water level. Our study's key achievements include the development and successful application of this innovative methodology, integrating basin water budget analysis with fish population growth predictions across varying flow conditions. This approach allows the identification of potential ecosystem risks like water scarcity or pollution and determines the optimal ecological flow needed for maintaining the river ecosystem. Our research provides valuable insights for future endeavors in sustainable water resources management and river ecosystem conservation efforts. |
