Deltares: Modelling Storm-Impacts on Gravel Coasts

Gravel beaches occur on many wave-dominated coasts across the world and are widely considered an effective and sustainable form of coastal defense.

Despite their societal importance, relatively little research has been directed towards understanding the mechanisms leading to their failure during storms.

As a result, coastal managers have very limited guidance when estimating the potential for flooding on gravel coasts.

Robert McCall addressed the current gap in predictive storm-impact models for gravel coasts in his doctoral research at Plymouth University UK, in collaboration with Deltares and project partners the Channel Coastal Observatory, the Environment Agency, HR Wallingford and UNESCO-IHE, as a part of the NUPSIG project.

His research resulted in the development of a new, process-based, open-source numerical model called XBeach-G.

The XBeach-G model, which is based on the existing open-source model XBeach, simulates the impact of storms on gravel beaches and barriers by solving the hydrodynamics of individual waves in the nearshore and swash zone, wave run-up and overtopping flows, groundwater processes in the beach and barrier, sediment transport and morphological change of the beach during the storm.

To ensure easy uptake of the XBeach-G model by coastal managers and engineering firms, Deltares and Plymouth University have developed a free and easy-to-use graphical user interface (GUI) for the XBeach-G model.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
