HEC-HMS 모형을 이용한 홍수피해 저감대안 평가

Evaluation of Flood-Damage Reduction Alternatives Using HEC-HMS

This paper presents how effective the detention storage is to control floods at a test watershed. HEC-HMS model was applied to simulate the effects of the storages of different levels and installation methods on the flood peak reduction. The results showed that the detention storage may significant reduce the flood peaks, and the effectiveness depends on the sizes of the storage and types of installation. The simulated peak values reduce considerably for the design storm events. The results also showed that alternatives to control flood may be evaluated using the model.
