The MARID research group is an informal collection of researchers from anywhere in the world. We form this research group as we believe that together we can better identify areas for future investigation and solve problems via cross-disciplinary collaboration. There is no membership or joining fee.

If you want to be on the MARID mailing list, please email maridwebsite@gmail.com with “mailing list” in the subject line of your email.

A newsletter will be sent every 3 months to update the community about upcoming meetings, recent publications, available datasets, toolboxes and funded projects.


Under the aegis of the North Sea Hydrographic Commission, a workshop on marine sand wave dynamics was organised by the French Naval Hydrographic and Oceanographic Office (SHOM) and the University of Lille 1 (France) back in 2000. This workshop was succeeded by conferences covering marine and river dune dynamics in 2004 (University of Twente, Enschede, The Netherlands), in 2008 (University of Leeds, United Kingdom), in 2013 (Royal Belgian Institute of Natural Sciences, Belgium), in 2016 (Bangor University, North Wales, United Kingdom), and in 2019 (MARUM, University of Bremen, Germany).

Now known by the acronym MARID, these conferences provide state-of-the-art overviews in fundamental and applied knowledge of marine and river bedforms, from shallow to deep water, and from small to large-scales.


Bedforms form as a result of turbulent shear generated by the interaction of a fluid flow with underlying mobile sediment. This interaction is complex, with bedforms having varying dimensions, geometries and degrees of mobility. The processes governing bedform dynamics have still not been unraveled adequately, yet MARID researchers are making progress across a wide number of disciplines, including hydrography, fluid dynamics, oceanography, earth sciences, sedimentology, laboratory experimentation, numerical modelling, and field quantification.
