Abstract

We investigate the influence of wind waves and wind-driven flow on sand wave
dynamics using a two-model approach. Using a linear stability analysis, we find that waves decrease sand wave growth and wind causes sand wave migration. Combining linear stability analysis
with a typical North Sea wave and wind climate explains variability in sand wave migration rates.
Using a nonlinear sand wave model we show that waves reduce sand wave height and wind causes
sand wave asymmetry as well as migration.
