Based on the measurements of runoff, mean soil erosion depth, and sediment yield, etc., the results suggest the following characteristics in the process of surface erosion in the experimental area. (1) The occurrence of sediment discharge is interrupted; (2) Surface runoff is a saturated overland flow; (3) The mean soil erosion depth is thick compared with other areas in Mt.Tanakami; (4) Sediment discharge process is detachment-limited.展开更多
