Abstract

This study finds that by introducing a channel form factor (width/depth ratio), the self-adjusting mechanism of alluvial channels can be illustrated directly with the basic flow relations of continuity, resistance and sediment transport. The theoretical results obtained here demonstrate that maximum flow efficiency (MFE) determines stable alluvial channel geometry and that this is a product of both maximum sediment transporting capacity (MSTC) and minimum stream power (MSP). Furthermore, this study indicates that the existence of MFE, MSTC and MSP can be satisfactorily explained in terms of the physical principle of least action
