HR Wallingford: Modelling Colwyn Bay’s New Beach Defense

Conwy County Borough Council recently hired HR Wallingford to conduct physical modelling of the Colwyn Bay’s new beach defenses.

“The Council wants to assure the longevity of the new beach, which has to date involved the placing of approximately 500,000m³ of dredged material, and has commissioned HR Wallingford to conduct physical modelling to estimate its future lifespan, taking into account the coastal storms that this area is exposed to,” HR Wallingford said in its latest release.

In a 35m x 50m wave basin in its modelling facilities in Oxfordshire, HR Wallingford’s coastal engineers have created a detailed physical model of a 1.6 mile (2.6km) section of Colwyn Bay at a scale of 1:50, from Rhos Jetty in Rhos on Sea, eastwards towards Beach Road, Old Colwyn.

A bank of 56 individual wave generators, with wave probes placed in the basin to measure the waves generated, is being used to simulate typical weather and storm conditions.

Tom Rigden, Senior Scientist, Coastal Structures at HR Wallingford, said: ”We’ve been working closely with Conwy Borough Council, and with Alan Williams from Coastal Engineering UK, and drawn on their experience of the site, which has enabled us to ensure the physical model accurately replicates the natural processes that Colwyn Bay is exposed to.”

According to the company, engineers are using the complex physical model to calculate the rate of loss of the beach-line, and give an estimate of the number of years it will take to erode, as well as advise on possible further protection measures if required.

Tests using the physical model will take several months, and are due to be completed at the end of March 2017.

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.
