Abstract

Tidal sand waves are rhythmic bedforms usually found in tide-dominated shelf seas (e.g., the Dutch Continental Shelf, Figure 1). They are characterized by wavelengths of 100 - 1000 m, heights of 1 – 10 m and migration rates of 1 – 10 m/yr (van Dijk & Kleinhans, 2005). It is recognized that tidal sand waves generate form roughness that affects the hydrodynamics on a larger spatial scale. However, in basin-scale hydrodynamic models (that do not resolve the local sand waves), bed roughness is treated as a calibration parameter, and not directly linked to the local sand wave characteristics (Zijl et al., 2018).
