Numerical investigation of flow velocity and shear stress in a rough rectangular compound channel with single floodplain [PDF]
Flow in compound sections, due to the differences in velocity between the main channel and floodplains, is structurally quite different from that in simple channel sections. In the present research work, FLOW3D software was applied in a rough rectangular

Confluence morphodynamics in mountain rivers in response to intense tributary bedload input
Coupled physical and numerical modelling show mountain river confluence hydrodynamics and morphology resulting from coarse sediment transported during high magnitude rainstorm events are influenced by a multitude of factors. In addition to the confluence angle and discharge ratio, sediment concentration and hydraulic attributes strongly influence the ...
