3.4. Effects of slope with constant Re and us
Lastly, halving the slope from 0.04 to 0.02 has a remarkably small effect on the development of sediment waves on
the ramp (see figure 6). Several sets of upslope-migrating waveforms still develop. The primary difference between
this set of simulations and our baseline case is that here the flows are no longer net-erosive anywhere on the ramp.
So the decrease in potential energy and gravitational acceleration of the sediment-laden fluid does result in a small
decrease in erosive potential, but not enough to significantly dampen the development of waveforms. Overall, it
appears that a better understanding of erosion on the microscale is critically important to any real understanding of
