Tanakami. Based on the measurements and analysis of runoff, mean soil erosion depth sediment yield and semiment transport, etc., the characteristics in the process of surface erosion in the experimental area are as follows: the occurrence of sediment discharge is interrupted, with a saturated overland-flow surface runoff; the mean erosion depth is 0.086 2 cm, which is thicker compared with other areas in Mt. Tanakmi; sediment yield is 431. 283 m3·km?2, whose process is detachment-limited, and the type of sediment transport is a sediment flow.

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
