Abstract

The AA. quantitatively test the hypothesis that soil freeze-thaw (FT) processes significantly increase the potential for upland hillslope erosion during run-off events that follow thaw. They selected a highly frost-susceptible silt to obtain an upper bound on FT effects, and completed 3 series of 6 experiments each to quantify differences in soil erosion and rill development in a bare soil following a single FT cycle. As both FT and C results were highly sensitive to initial conditions, minimum differences in soil weight, bulk density and soil moisture through each series of experiments were required to achieve consistent results, indicating that rill erosion may be chaotic
