Abstract
Flow past a spur dyke on a rigid bed meandering channel with a trapezoidal cross section has been studied experimentally. An acoustic Doppler velocimeter (ADV) was used to measure the velocities. The results show that length of the downstream separation zone changes according to the location of the spur dyke. It varies from 4.0 to 22.8 times the spur dyke length. In addition, the separation zone at higher elevations is wider compared to that near the bed for most of the locations of the spur dyke. The effect of contraction ratio and inflow Froude number on separation zone is also presented.
