Abstract

This paper examines the use of lateral distribution method (LDM) and modified LDM in the computation of depth-averaged velocity distributions and boundary shear stress distributions of compound channel having converging floodplain. In two-stage channel flow, the main channel is influenced by the adjoining floodplains and the conveyance capacity is normally decreased. The many-sided quality of the issue rises progressively when dealing with a compound channel with non-prismatic floodplains. Due to change in floodplain geometry, water streaming on the floodplain now traverses in the main channel, resulting in increased interaction and momentum exchange. This additional exchange in momentum should also be considered in the flow modelling. In this research work, the modified LDM equation considers friction slope and LDM equation is discretized by finite difference scheme, and for solving those equations, MATLAB tool is used. Depth-averaged velocity distributions and boundary shear stress distributions obtained from LDM and MLDM are compared with the experimental data sets.
