A stream flowing in alluvium deforms its bed surface so as to form ripples, dunes, bars, etc., and, in many instances, it deforms its channel as a whole so as to create meandering or braiding patterns. One can say that, in general, an alluvial stream and its deformable boundary undergo a variety of fluvial processes leading to the emergence of a multitude of fluvial forms.

This book concerns the physics and analytical treatment of fluvial processes and the associated alluvial forms. The emphasis is on the origin, time-development and effects of bed forms, from small to mesoscale...
