Abstract

Three soil surface characteristics are relevant to determine the runoff potential of cultivated soils : soil cover by crops and residues, soil surface crusting and roughness. These characteristics have been observed on 65 cultivated fields throughout 2005. A heavy rainfall event representative for events triggering muddy floods in the region has been simulated with the 17 most observed combinations of soil surface characteristics in central Belgium. A classification of runoff generation risk based on the surveys of soil surface characteristics has been applied to common crops of central Belgium. It appears from monitoring of a 16 ha catchment that the highest runoff volumes and peak discharges are recorded between May and August after heavy rainfall, explaining why 85% of muddy floods are recorded during this period in central Belgium
