Description :
This paper examines rates of bed load movement through stream channels by relating annual travel distance to simple basin or channel characteristics such as reach-averaged basal shear stress, drainage area or bankfull channel width. The intent of this analysis is to identify simple estimators of sediment movement rates that are less difficult and expensive to apply than commonly cited bed load transport equations. These relationships can be used to estimate how quickly sediment moves through a reach for planning restoration of stream habitats in the western USA and other regions with similar channel characteristics and sediment supply.
