- Abstract
In this study, we demonstrate an approach for citywide urban flood vulnerability assessment based on the capability of storm-water drainage networks. The daily rainfall data of 45 years were used to generate intensity-duration-frequency curves of 2, 5, 10, 50 and 100-yr return periods. The performance of the storm-water drainage network was subsequently evaluated for each of these probable storms using rainfall-run-off simulations employing the SWMM software of US EPA. The duration of flooding at drainage nodes under storms of different return periods was considered for identifying flood-prone regions in the study city. It was observed that about 21% of the city is currently under high and very high urban flood severity zones.
