Abstract

Using the profile data of 113 channel cross-sections taken in 1962, 1982, 1991 and 2000 in the Kubq desert reach of the Yellow River, the AA. show that the lateral channel erosion rate remained relatively constant despite flow decreases of 58% and led to the development of a unique bank-to-channel sediment transfer (BCST). This BCST process, in combination with the decreased flow which caused suspended sediment effluxes to decrease by 30%, enhanced sediment deposition in the channel and provided a mechanism of channel adjustment to decreased flow in sand-banked rivers. As the lateral channel erosion is a substantial sediment source of river sediments, about 64%, and leads to lateral channel shifts for sand-banked rivers, channel bank stabilization should be a priority in river management and flood control in sand-banked rivers
