A review on applications of urban flood models in flood mitigation strategies

Abstract

As a result of climate change, urban areas are increasingly vulnerable to flooding, which can cause devastating effects, both in terms of loss of life and property. Therefore, an accurate assessment of urban flood processes and improved pre-disaster mitigation strategies in threatened areas is essential. Urban flood modeling enables users to understand, assess, and forecast flood conditions as well as their impact. For effective flood modeling, especially in highly urbanized floodplains, model selection based on the contextual requirements is a challenge. This review provides a systematic overview of the application of urban flood modeling approaches from the perspective of urban flood strategy design sequences. In this review, recent research advances are presented as well as suggestions for future research topics that will improve the availability and reliability of urban flood modeling methods. The results of this review will help urban flood managers and potential users balancing model complexity and needs while undertaking effective flood modeling tasks.
