ABSTRACT

The increasing migration of people to urban areas around the world contributes to increasing man’s adverse impact on the environment and therefore on climate change which is an issue that presents one of the most important challenges of modern civilization. In urban areas, this impact leads to the occurrence of many extreme events, which means multidimensional losses. Over the decades, hydrological catastrophes, especially floods, have been studied so as to control and monitor risks. However, this type of risk assessment has to meet multiple objectives that often conflict with each other. This paper proposes a multidimensional framework which allows researchers to use approaches that support decision makers in the modelling and analysis of the risk of flooding in urban areas. This includes rating risk while considering multiple factors and to responding to risk using actions, such as mitigation measures, which prioritize preventive actions to combat disasters throughout a cyclical process. Some potential benefits of using this approach are discussed.
