Factors affecting conveyance in meandering compound flows

This paper brings together recent data from the large-scale Flood Channel Facility, Wallingford, England, with other model studies to investigate the main parameters affecting conveyance in meandering compound river channels. Parameters investigated include sinuosity, boundary roughness, main channel aspect ratio, width of meander belt, and flow depth above bank-full level as well as the cross-sectional shape of the main channel. The effect of each parameter is quantified through a nondimensional discharge coefficient \IF\N×. Possible scale effects in modeling such flows are also investigated.
