Sand Bar Movement
Predictions of the fate of sand nourishments in the nearshore are critical to the management of eroding shorelines. The effectiveness of these nourishments depends on wave and current conditions, which vary with nourishment shape, size, and location. Here, observations of an artificial sand mound in a new laboratory experiment are examined to characterize the impact of a range of wave and current conditions on mound evolution and to inform coastal management techniques. Results from this experiment and previous studies of sandy mounds in the field are combined to determine the balance of hydrodynamic processes controlling mound diffusion.
