Abstract
Surface weathering accelerates soil erosion. Wet-dry cycles, freeze-thaw cycles, crust development, and cracking are a few of the processes that can weaken the soil surface and increase erosion. A headcut was formed in a compacted cohesive soil and subjected to weathering cycles and intermittent flows. Dessication cracks formed relatively quickly after a flow event. Weathering appeared to cause half as much soil erosion as plunge pool scour. Weathering typically weakened a 25 to 50 mm thick soil surface layer.
