Reservoir storage of flows responsible for scouring sandbars has resulted in the encroachment of vegetation along many rivers such as the Platte River, Nebraska, and greatly reduced channel width (Currier et al. 1985, O(Brien and Currier 1987, Eschner et al. 1981, Lyons and Randle 1988, Sidle et al. 1989, Stinnett et al. 1987). ................
