Bedload equation for ripples and dunes

Abstract

A simple bedload transport equation based on the mean forward velocity and mean height of ripples and dunes is applied to 101 observations from flume studies by using a recirculating flume and four different sands. Where average dune velocities and heights are determined accurately with sonic equipment, and where suspension of bed material is negligible, the computed and observed transport rates of bed material agree reasonably well. General guidelines for adapting the procedure to field applications are given.
