Abstract

In the present study, on the basis of the generalized experimental data of compound channels, and the regional characteristics of flow and sediment movements, four regions were proposed according to the compound sections of channels and plains. These included the undisturbed regions in the main channels; interactive regions between the channels and the plains; undisturbed regions in the floodplains; and the boundary regions. The interactive regions between the channels and plains, which were characterized by the most complicated water flow regimes, were further divided into logarithmic flow velocity zones (inner zones) and non-logarithmic flow velocity zones (outer zones). Then, by introducing an S-shaped curve, a method for determining the boundary between the inner zones and outer zones was proposed. The water-sediment exchange intensity in the interactive region is higher than that in other areas, so it is a key point in the study of compound channel.
