Abstract

Contemporary field study by survey and sediment tracing using the magnetic technique indicates the present instability of the sediments in a meandering channel given a trapezoidal cross-section and varied banks. Low-flow adjustments are as important as flood adjustments in the lower, straightened reach. Lessons for engineering schemes include the desirability of assessing erosion risk by rapid, cheap field techniques and historical investigations, and the consideration of more ecologically acceptable channel designs
