Abstract

Comparison of a dataset with 28 deep gullies, formed in the period 1985-2003 and 123 shallow ephemeral gullies formed in the period 1994-1999 in central Belgium indicates that the deep gullies have clearly different morphological characteristics compared to shallow ephemeral gullies. Several factors were analyzed to understand the formation of deep gullies. The relation between area-specific sediment yield in central Belgium and drainage area, indicates that the development of deep gullies contributes significantly to the sediment output of small rural catchments and causes peaks in the mean area-specific sediment yield that are up to a factor of 3 higher compared with catchments where shallow ephemeral gullying occurs
