Factors Controlling the Spatial Distribution of Soil Piping Erosion on Loess-Derived Soils: A Case Study from Central Belgium

Collapsible loess-derived soils are prone to soil piping erosion, where enlargement of macropores may leadto a subsurface pipe network and eventually to soil collapse and gully development. This study aims atunderstanding the main factors controlling spatial patterns of piping in loess-derived soils under a temperateclimate. To map the spatial distribution of piping and identify the environmental controls on its distribution,a regional survey was carried out in a 236 km2 study area in the Flemish Ardennes (Belgium). Orthophotostaken at optimal field conditions (winter) were analyzed to detect... Mehr ...
