- W1981734460 abstract "본 연구에서는 상하류간의 유출특성을 고려하여 관측망을 구축하는 방법에 초점을 맞추어 수위관측망을 평가하였다. 최적 수위관측망을 구축하기 위해 상하류의 유출특성을 반영한 대표단위도를 실제 강우-해석을 바탕으로 유도한 후 확률밀도함수로의 전이를 통해 엔트로피 이론에 적용하였다. 이를 충주댐 유역에 대해 상하류간의 유출특성을 고려한 경우와 기존 방법론인 경험식을 이용하여 수위관측망을 구축한 경우를 비교하였다. 그 결과를 정리하면 다음과 같다. 상하류간의 유출특성을 고려한 수위관측망의 경우는 경험식을 이용한 경우보다 적은 수위관측소가 선정됨에도 불구하고 더 큰 정보전달량이 산정되었다. 이는 구축된 수위관측망의 정보전달량이 상류 및 하류단의 수위관측소의 유출특성을 보다 잘 대변하기 때문으로 판단된다. 아울러 대상유역인 충주댐 유역에서는 총 18개의 수위관측소 중 12개의 수위관측소가 필요한 것으로 판단되며, 이는 상하류간의 유출특성을 반영한 최적 수위관측망이다. This study has evaluated the stream gauge network with the main emphasis on the methodology of optimal stream network which is considered the discharge characteristics between upstream and downstream. To evaluate the optimal stream gauge network, the representative unit hydrograph which is considered the discharge characteristics between upstream and downstream is transferred into probability density function for application of the entropy concept. This study has been compared the case of considering discharge characteristics between upstream and downstream and the case of the conventional methodology of using empirical formula and applied to the Chungju dam basin. Summarizing the results are as follows. It can be found that the large total information content is estimated at the case which is considered discharge characteristic between upstream and downstream more than the case which is applied empirical formula even though the few stream gauge stations is selected. It means that the total information of selected stream gauge stations is represented well the discharge characteristic between upstream and downstream. The Chungju dam basin is found to need at least 12 stream gauge stations, which was derived by considering the discharge characteristic between upstream and downstream." @default.
