Abstract
The purpose of this research is to analyze sensitivities on hydraulic characteristic factors of bridge and culvert causing flood water level rising. With HEC-RAS and RMA2 models, analysis of backwater due to bridge and culvert in an ideal stream was carried out. The results of hydraulic modeling and sensitivity analysis indicated that the opening ratio and the Froude number were the most sensitive factors and other factors were not quite sensitive to flood water level rising.
