| Bedforms originating from imposed surface waves (after Yalin 1972). t is time, x is distance from the start of the erodible bed, qs is sediment transport rate, dqs/dx is rate of change of qs with respect to distance, l is water surface wavelength, L is bed wave length, and D is bed amplitude. Note the direct relationship between zones of erosion and deposition and dqs/dx. | |
