Regeneration of dredged sand waves

Sand waves form a wavy pattern in the offshore sandy seabed. Since their crests reduce the navigability, it is important to know their evolution. A simple model is presented to estimate the recovery of sand wave amplitudes. This model is partially based on the similarity with sea ripples and partially on bathymetry measurements. No further information is needed. The model reproduces the data very well. Using this model, it is possible to evaluate different dredging strategies
