Abstract

Flooding in urban area affects the lives of people and could cause huge damages. In this study, a model is proposed for urban flood management with the aim of reducing the total costs. For this purpose, a hybrid model has been developed using SWMM and a quasi-two-dimensional model based on the cellular automata capable of considering surface flow infiltration. Based on the hybrid model outputs, stormwater management measure scenarios are proposed. In the next step, a damage estimation model has been developed using depth-damage curves. The amount of damage has been estimated for the scenarios in different rainfall return periods to obtain the damage and cost- probability functions. The conditional values at risk are estimated based on these functions which are the basis of decision making about the stormwater management scenarios. The proposed model is examined in an urban catchment located in Tehran, Iran. In this study, five scenarios have been proposed on the basis of different stormwater management measures. It has been found that the scenario of using permeable pavements results in the lowest risk. The proposed model enables the decision makers to choose the best scenario for the stormwater management with the minimum cost taking into account the risk associated with each scenario.
