Description :
The aim of this paper is to refine previous conceptual models of muddy flood triggering by determining rainfall and topographic thresholds for the Belgian loess belt as well as to quantify off-site impacts of muddy floods. Twenty municipalities in central Belgium have been selected for a detailed analysis. A database of 367 locations affected by muddy floods has been compiled, and the connectivity between cultivated areas and inhabited zones could be assessed for 100 flooded locations. Three types of areas producing muddy floods have been identified. The most suitable control measures are then reviewed.
