Abstract

This study proposes a simple mathematical model of channel bifurcation, in which a channel head is modeled by an opening on a flat plane composed of erodible bed material. A linear stability analysis is performed with the use of the depth-averaged momentum equations of flow and the Exner equation of beds subject to erosion. The analysis shows that channel bifurcation tends to take place as the discharge attracted by the channel head decreases.
