Data for: sheet flow resistance induced by raindrop impact

Experimental setup: the flume was 6.0 m long, 0.25 m wide, and 0.3 m deep. The bed of the flume was impervious.

Three different bed surfaces were used: a smooth surface (equivalent roughness = 0.009 mm); a 120 mesh gauze bed (equivalent roughness = 0.12 mm); and a 60 mesh water gauze bed (equivalent roughness = 0.25 mm). Two sets of flume experiments, namely, upstream-inflow-alone experiments and upstream-inflow-with-rainfall experiments, were designed. In upstream-inflow-alone experiments, three constant inflow discharges (0.02, 0.04, 0.06, 0.08 and 0.1 m2 min-1) and three kinds of bed surfaces were designed to simulate SF under different surface conditions.
