Abstract

The sedimentation of loess in a 40 km2 area on the northern border of the Belgian loess belt, is investigated by means of wind tunnel experiments. Loess deposition is simulated on a relief scale model for different wind directions. Simulation with northeast winds produces a loess deposition pattern that coincides closely to the field pattern, which may be an indication that the loess-bearing winds at the end of the Weichselian came from the northeast. Loess deposition occurs preferably on windward slopes and not on leward ones. The wind-shadow concept, which is important in the case of sand deposition may not apply to fine materials such silt and clay
