Abstract

  • The article presents the current development of a methodology to assess flood risks due to contaminants with a high spatial resolution. The integrated approach combines methods from flood risk analysis with those from contaminant risk assessment. It focuses on toxicological receptors of urban areas represented by land-use data. For each receptor risks are analyzed considering the hydrodynamic contaminant distribution and the exposure of specific receptors. These risks cover both the recurrence probability of certain flood events with their matter fluxes and the exposure of receptors with dose-response relationships. GIS is used for data management, calculation of algorithms and display of the results in a DSS.
