3.2. Effects of Re with constant us and slope
Increasing the Reynolds number from 2,000 to 3,000 greatly dampened the development of sediment waves on
the ramp (see figure 4). We infer that the main reason for this is that an increased Reynolds number implies a larger
effective characteristic length scale (if viscosity, gravity etc. are kept constant), and thus a larger effective particle
diameter. As the Reynolds number increases, with all other parameters remaining the same, erosion decreases.
