International audience ; During the previous decade, 68 per cent of the municipalities in the Belgian loam belt have been confronted with muddy floods from agricultural catchments after intense rainfall. Runoff concentrates in dry valleys and causes damage to infrastructure and housing property downstream. A typical problem area is the village of Velm where a permanent river is constrained by a culvert designed to accommodate its peak discharge.
