Potential Use of BEST® Sediment Trap in Splash - Saltation Transport Process by Simultaneous Wind and Rain Tests

摘要: The research on wind-driven rain (WDR) transport process of the splash-saltation has increased over last twenty years as wind tunnel experimental studies provide new insights into mechanisms simultaneous and transport. present study was conducted to investigate efficiency BEST® sediment traps in catching sand particles transported through under WDR conditions. Experiments were a rainfall simulator facility with water sprayed sprinkler nozzles free-flowing at different velocities simulate Not only for vertical distribution, but series tests horizontal distribution sediments also performed using collectors obtain actual total mass flow by center test section. Total (kg m-2) estimated analytically integrating exponential functional relationship measured amounts set trap heights every run. Results revealed integrated 6, 9, 12 15 m s-1 55.8, 50.5, 55.0 50.5 mm h-1 intensities were, respectively, 83, 106, 105, 102%. well showed that efficiencies did not change much compared those rainless condition.
