DescriptionBed load transport is a fundamental physical process in alluvial rivers, building and maintaining a channel geometry that reflects both the quantity and timing of water and the volume and caliber of sediment delivered from the watershed. A variety of formulae have been developed to predict bed load transport in gravel-bed rivers, but testing of the equations in natural channels has been fairly limited. Here, I assess the performance of 4 common bed load transport equations (the Meyer-Peter and Muller , Ackers and White , Bagnold , and Parker  equations) using data from a wide range of gravel-bed rivers in Idaho. Substantial differences were found in equation performance, with the transport data best described by a simple power function of discharge. From this, a new bed load transport equation is proposed in which the coefficient and exponent of the power function are parameterized in terms of channel and watershed characteristics. The accuracy of this new equation was evaluated at 17 independent test sites, with results showing that it performs as well or better than the other equations examined.
