SCS TR-20 모형을 이용한 미계측 소유역의 홍수유출량 추정

Estimating Peak Runoff from Small Ungauged Watersheds Using SCS TR-20 Model

The objectives of this study are to evaluate the applicability of SCS TR-20 model for small ungauged watershed, to show the behavior of the model with variation of topography in watershed, and to evaluate the storage effect of paddy field for flood flow. For this purpose, simulated data from the model were compared with the observed flood data at two sites (HS#3, HS#4) in Balan watershed. From the comparison between simulated and observed data, it was found that the model is applicable to this watershed.
