Abstract

In rivers with a compound section, typically the relatively high roughness of floodplains, as compared with the main channel, cause to flow speed difference between the main channel and the floodplain. The velocity dissimilarity also creates shear layers at the interface point of the main channel and the floodplain. The development of shear layers will also cause turbulence in the mutual plane of the main channel and the floodplain. In such conditions, the average flow speed cannot be applied to compute parameters such as shear stress, bed-load discharge, and so forth. In this research, laboratory experiments were carried out to study the effects of floodplain divergence on flow hydraulic and the rate of Sediment transport for different roughness and divergent angles. 36 tests were done at a concrete flume with Compound channel cross section (9 and 27 tests with prismatic and non-prismatic cross section, respectively).-The velocity in different sections were measured using a micro-propeller and ADV (with 200 Hz frequency) for depth ratio of 0. 15 and 0. 25 and for depth ratio 0. 35, respectively. . The results reveal that the increase in all three factors of the roughness, divergence angle, and relative depth cause dramatic changes in the hydraulic of the flow and the Sediment transport.
