Estimation of economic damages caused by the flood risk

Abstract

In recent years, we have become increasingly aware of the importance of factoring the risk to people, property, the overall economy and the environment from flooding into the planning system, and the role that good planning has in avoiding and reducing such risk that could otherwise arise in the future need to pro-actively manage flood risk. There are many areas, including towns and cities that are already at risk from periodic flooding. One of them is Jijia hydrographic basin is characterized by frequent and sharp variations of flow volumes and levels which lead to floods and flooding throughout the basin. Dorohoi town is located in this basin and experienced a significant flooding from a heavy rainfall event in June 2010. The article describes the undergoing work on model development to estimate the damage that was produced by this flash flood. Different land-use data sets have been used to represent the uncertainties in the exposure, value and susceptibility components. For the flood hazard component, inundation depth has been varied systematically to estimate the sensitivity of flood damage estimations to this component.
