Assessment of floodplain tree density variation on discharge conveyance capacity and flow velocity in meandering compound channels

Abstract Three different mangrove tree densities (sparse, average, and dense) on a meandering compound channel floodplains were used to assess the effects of rigid trees on the conveyance capacity, streamwise velocity variation, and distribution at the main channel. The numerical simulations were carried out using a Computational fluid dynamics (CFD) model under non-vegetated (reference) and vegetated conditions, considering three relative depths of 0.26, 0.35, and 0.45 along with their correspo
