We discuss two cases of international cooperation between hydrographic offices. The first case is the unified approach to populate the CATZOC indicator for bathymetric quality in nautical charts, in the presence of sand wave fields. The second case is the North Sea wide formulation of resurvey policies. The two cases can only be successful if it is understood and agreed how the sea floor develops. For both of the cases, it is very relevant to distinguish between the growth of a pattern, and its migration. Therefore, hydrographic offices need accurate morphodynamic models, an appropriate set of methods for the analysis of time series of bathymetric data, and versatile remote sensing techniques. The two cases are discussed using the example of a sand wave field near the Port of Rotterdam, in the Southern North Sea. The development of the field is potentially influenced by the maintenance of dredged channels and an emergency turning zone; extensive sand pits; and two infrastructural projects in the coastal vicinity: Maasvlakte 2 and the Zandmotor.
