Numerical Simulation of Sand Wave Evolution in Shallow Shelf Seas

Abstract

Sand waves form a prominent regular pattern in the offshore seabed of sandy shallow seas. A 2DV morphological numerical model describing the behaviour of these sand waves is under development. The first goal is to make the new numerical model reproduce the results obtained with a linear stability analysis. We start with a constant current after which the behaviour of sand waves is investigated in a tidal environment. Furthermore, calculations using Delft3D have been made to test the general setup of the new numerical model.
