Flood risk assessment and flood damage evaluation – the review of the case studies

Abstract

This article presents a brief overview of selected flood risk and flood damage assessment studies. The assessment on the Luvuvhu River focused on risk assessment based on hazard and vulnerability parameters. To these parameters was added another parameter, the exposure parameter in the assessment in the study of Sri Lanka. Hazard, vulnerability and exposure assessment were also performed on the Yangtze River in China, where the authors presented a proposal for a multi-index flood risk assessment concept. The output of these studies are flood risk maps for each indicator, as well as individual risk assessments in the given area. The next section is focused on the flood damage evaluation. The main tool for calculating flood damage in a study conducted in Beijing is flood risk. The calculation process focuses on the Integrated Flood Management (IFRM) method, which consists of risk identification, damage assessment and flood management to design flood protection measures. In flood management, the term vulnerability often occurs, which is a weakness or shortcoming that allows the hazard to be applied. Closely related to this concept is the sensitivity parameter, which can be used to estimate flood damage in the next case study in affected area in Netherland. The last of selected studies presents the application of the RESTful Application Program Interface (API) for the financial estimation of building damage. The API web service allows you to calculate flood damage to buildings without determining the flood risk.
