Abstract

Using long-term discharge and cross-sectional data in combination with a two-fraction sediment transport model, the AA. assess changes in the downstream bed of 2 flow-regulated rivers with equivalent dam-induced changes in flow but opposite changes in sediment flux. Supply limitation has led to incision and armoring in one case while supply excess has led to aggradation and embeddedness in the other. The results demonstrate the importance of considering bed composition on sediment transport predictions and the development of management strategies for ecosystem maintenance
