- W4213306722 abstract "본 연구에서는 다방향 흐름 분배 알고리듬과 실시간 유출 보정 알고리듬을 이용하여 개발한 분포형 강우 유출모형의 실제 유역에 대한 적용성을 평가하였다. 안동댐과 남강댐 유역에 대해 각각 우량계 관측자료와 레이더 관측 우량자료를 이용하여 분포형 강우-유출 모의를 수행하였다. 이전의 호우사상에 대한 유역 매개변수 보정 실시 후 보정된 매개변수를 이용하여 다른 호우사상에 대해 모형을 적용하였다. 안동댐 유역에 대해 흐름 군집화 결과를 제시함으로써 다방향 흐름 분배 알고리듬의 흐름추적에 대한 물리적 타당성을 입증하였다. 다방향 흐름 분배 알고리듬을 이용하여 정확도를 유지하면서 계산소요시간 단축이 이루어졌으며 실시간 유출 보정 알고리듬의 적용을 통해 좀 더 향상된 정확도를 갖는 결과가 도출되었다. 본 연구에서 개선된 유역 홍수관리를 위한 분포형 강우 유출 모형의 활용가능성을 제시하였다. The applicability of the developed distributed rainfall runoff model using a multi-directional flow allocation algorithm and a real-time updating algorithm was evaluated. The rainfall runoff processes were simulated for the events of the Andong dam basin and the Namgang dam basin using raingauge network data and weather radar rainfall data, respectively. Model parameters of the basins were estimated using previous storm event then those parameters were applied to a current storm event. The physical propriety of the multi-directional flow allocation algorithm for flow routing was validated by presenting the result of flow grouping for the Andong dam basin. Results demonstrated that the developed model has efficiency of simulation time with maintaining accuracy by applying the multi-directional flow allocation algorithm and it can obtain more accurate results by applying the real-time updating algorithm. In this study, we demonstrated the applicability of a distributed rainfall runoff model for the advanced basin-wide flood management." @default.
