부정류 모형을 이용한 하천 조도계수 산정 및 산정오차의 수면곡선에 대한 민감도 분석
Manning's n Calibration and Sensitivity Analysis using Unsteady Flood Routing Model
초록
This study is to figure out uncertainty relationship between input data and calibrated parameter on unsteady hydraulic routing model. The uncertainty would be present to model results as a variant water surface profile along the channel. Firstly, Manning's n is calibrated through the model with assumed uncertainty on input hydrograph. Then, spatially distributed n-values sets based on the calibrated n values are used to get water profile of each n-values set. The results show that
