수리권을 고려한 동진강 하천유지유량 변화의 예측 = Prediction of Variations for Instream Flow in Dongjin River Watershed with Considerations of Water Rights

다국어 초록 (Multilingual Abstract)

Water rights are the right of a specific person to use river water continuously and exclusively. In the case of domestic water rights, Public river water rights, conventional water rights and permitted water rights are mixed. So, There are inter-regional disputes for the water rights. However, There is a lack of hydrological research to support institutional research.
In this study, the Dongjin basin was selected as the research target area, the TANK model was applied to calculate the naturalized stream flow, and based on this flow, the WRAP model was used as an analysis tool for water rights.
In the case of the naturalized stream flow of the Geosangyo through the TANK model, was 0.657, NSE was 0.615, and RMSE was 17.971. Considering the frequent use of agricultural water, it was found that the simulated values can appropriately correspond the observed values.
We simulated variations in stream flow due to water rights in the Dongjin basin. The compared flow station is the Jeongugyo, where the instream flow of 1㎥/s is announced. The statistics between the regulated stream flow with the WRAP model and measured data show 0.821, NSE 0.649, and RMSE 34.473. So, It was regarded that the simulated results reflect the characteristics of the basin well.
The simulated scenarios were composed of conditions for supplying water inside and outside of the watershed. The estimated method within the basin is to increase the amount of discharge at the Seomjin River Dam by 1㎥/s flow rate. And other methods are to constantly discharge the Osung and Sucheong reservoirs.
As results in simulated scenarios, it showed that release flow rate of the Seomjin River Dam had a dominant influence, and it was evaluated that the scenario for the constant discharge condition of the reservoirs was also effective.
