III. Work of Running Water A. Erosion
23
III. Work of Running Water A. Erosion 1) Sheet flow
24
III. Work of Running Water A. Erosion 1) Sheet flow 2) Rill flow
25
3) Stream (gully) flow
26
III. Work of Running Water B. Transportation 1) dissolved load
27
B. Transportation 1) dissolved load 2) suspended load
28
B. Transportation 1) dissolved load 2) suspended load 3) bedload
29
Bed load – –Rolling –Sliding –Saltation
