Abstract

Bedforms superimposed on river dunes have been observed in many river systems worldwide, including the Rhine-Meuse delta. It is unclear under which circumstances they occur, and how they relate to flow conditions, sediment transport and the migration and morphology of the primary dune. Bathymetric data was acquired in the Dutch Waal river, with a high spatial and temporal resolution. The bathymetric data indicate that migrating bedforms of around 2-5m are superimposed on larger, active river dunes, and even occupy the lee side. Presented results further show the influence of primary dunes on the occurrence and size of superimposed bedforms.
