The objective of this study is to present a risk analysis method for flood protection level decision. The concept of “risk” is here defined as the product of flood damage and its occurrence probability. The study also presents a flood damage prediction model FDPM using GIS to calculate flood damages for any design storms with different return periods. The calculated monetary damages for the design storms with their occurrence probabilities enable us to quantify flood inundation risk as an Annual Risk Density Curve based on the concept of “risk.” FDPM and the risk analysis method were applied to the storm design level decision of the Kanda River in the Tokyo Metropolis. One example of the applications of the risk analysis method to optimal storm design level decision is presented with cost curves: Risk Cost Reduction Curve and Capital Cost Curve given by the Annual Risk Density Curve.
