| Abstract |
Recently, the need for water supply from hydropower dams has been increasing due to drought. In order to supply water through hydropower dam, the inflow into hydropower dam should be evaluated first. Some of the hydropower dams in the Han River basin are located downstream of multipurpose dam, so it is important to analyze its own inflow of the hydropower dam. The purpose of this study is to evaluate the contribution of inflow by water source to the hydropower dam located in the Han River basin. Water use-related data provided by various domestic institutions were investigated and collected, and a location-based water supply and demand network was constructed. Unlike the existing domestic water balance analysis method, the simulation was conducted in consideration of the amount of transmission loss. The applicability of the analysis method was confirmed through the results of the fitness evaluation (NSE 0.95~0.99 and correlation coefficient 0.98~0.99) comparing the simulated flow with the observed flow at the representative point. Based on the water intake method of the facility and the release method of the remaining multipurpose dam water, a water balance analysis was performed assuming four cases, and the contribution of inflow by water sources into each hydropower dam was evaluated and presented. The research results are expected to provide various information for evaluating the water supply capacity of hydropower dams in the future. |
