Estimating critical stream power for bedload transport calculations in gravel-bed rivers

Authors(s) and Affiliation(s)



The physical basis of Bagnold's equation for critical stream power is examined. More general equations are presented which overcome the limitations of this equation. They require a knowledge of channel slope, but not depth. The analysis suggests that the presence of form resistance in addition to grain roughness does not affect the calculation of critical power. Critical power is expected to depend more sensitively on grain size between reaches than within reaches
