A SLOPING DUCT FOR THE STUDY OF SEDIMENT TRANSPORT

[摘要] The details of a large sloping duct at HR Wallingford Ltd. are presented. The duct is capable of sloping to the angle of ±33° which exceeds the angle of repose of normal quartz sand. The duct can be tilted laterally as well as longitudinally so that; 1) the effect of combined slopes can be investigated; 2) the aspect ratio can be inverted. At present the duct operates with a steady flow but it can accommodate a wave piston.
