The numerical model named "DWOPER-LEV" for the uncertainty analysis of flood inundation is developed. DWOPER model is expanded to compute overtopping risks of levee and to predict the range of the possible flood extent. Monte-Carlo simulation is applied to examine the uncertainties in cross section geometry and Manning's roughness coefficient. The model is applied to an actual levee break of the South Han River. The risks of overtopping are computed and the possible range of inundated area and inundated depth are estimated.
