Abstract

A method for determining flow velocity distribution in the roughness sublayer is provided, which uses the experimental device that includes a variable-slope circulating flume system and a flow-measuring system, the variable-slope circulating flume system is used to study flow in the roughness sublayer, and the flow-measuring system is used to measure flow velocity in each zone in the flume. In the variable-slope circulating flume, the method according to the invention uses cylindrical aluminum rods to simulate large-scale roughness elements, and the submergence, the average bulk flow velocity and the distribution density of roughness elements are changed.
