Abstract

This paper reports flume experiments with a bimodal gravel/sand bed and sediment feed, designed to investigate river channel response to declining slope. The AA. simulated a series of sites along a concave profile approaching a local base level and undergoing a transition from gravel to sand bed; it also models the effect of a rise in base level on a fixed site. The results support the view that the gravel-sand transition along river channels with a local base level control is assisted by positive feedback between changes in bed surface texture and near-bed flow
