Abstract

Tidal sand waves are prominent bed forms occurring in coastal seas characterized by non-cohesive sediment deposits and relatively strong tidal currents (0.3 - 1.0 m/s). These bed features have a crest-to-crest distance between 100 and 500 m and are oriented approximately orthogonal to the main direction of the tidal current. Typical amplitudes are of the order of 1 to 10 m. Due to the ability of the bed forms to migrate, tidal sand waves pose serious hazards to many coastal structures such as pipe lines, monopiles and shipping lanes. Insight in the dynamics of these bed forms therefore is crucial for the long-term management of the coastal zone. In this work, we describe the development of a new generic numerical morphodynamic model to simulate the finite amplitude of tidal sand waves based on the hydrodynamic code SWASH.
