Abstract
In this study, we propose a simulating method to predict channel pattern in braided reach. Stream length which is defined as the distance from a channel bifurcating point to next bifurcating point, can be predicted by the channel width and the Froude number of the stream channel. We calculate the channel pattern using the channel length, separating rates of flow discharge and angles of channel bending at bifurcating paints.
The channel pattern calculated by the simulation model agree well with the experimental data. And also, the temporal variation of sediment discharge through braided channels can be estimated by this model.
