Abstract

(Topping-Leonard) Continuous measurements of sediment transport at reach-bracketing gaging stations allow for the construction of continuous mass-balance sediment budgets for the intervening reach. Although these budgets identify periods of sediment surplus (net deposition) or sediment deficit (net erosion), such analyses cannot identify the locations within the reach where channel change occurs. Because channel change and associated changes in habitat are of greater interest to river managers than the precise value of reach-scale loss or accumulation of sediment, it is important to explicitly link reach-scale changes in sediment mass balance to field measurements of channel change. In this study we will evaluate the relationship between the magnitude of the sediment mass imbalance measured by acoustic-Doppler profilers and the resulting channel change on the Yampa River in Dinosaur National Monument.
