Shen, Enshuai Data for: sheet flow resistance induced by raindrop impact Mendeley Data The experimental data were used to investigate and quantify the 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. In upstream-inflow-with-rainfall experiments, five rainfall intensities, 40, 60, 80, 100, and 120 mm h-1, were used to simulate rainstorms. The experimental data mainly include average flow velocity and water depth of whole flume. Water depth was measured in each 1 m by using a water level measuring needle. There were six observation points for measuring flow depth, positioned at 0.5, 1.5, 2.5, 3.5, 4.5, 5.5 m along the flume centreline. The mean water depth of the flume was the average of all measured points.
