Flood risk mapping at the local scale: Concepts and challenges

Abstract

Maps give a more direct and stronger impression of the spatial distribution of the flood risk than other forms of presentation (verbal description, diagrams). Thus, maps are valuable for presenting and assessing the local flood situation, and they provide information for many applications in flood defence and disaster management. In Europe, there are no standardised nomenclature or agreed practices for flood mapping. The paper reviews the concepts of flood risk mapping at the local scale, discusses the challenges and proposes a systematic presentation of flood hazards, vulnerabilities and flood risks, spanning from flood danger maps to damage risk maps.
