Cadzand Marina - Improvement of wave conditions
IMDC was enlisted to help resolve the wave action challenges at Cadzand-Bad marina, which were affecting both harbor tranquility and visitors' comfort. Through measurements and wave agitation modeling, practical solutions were proposed, including a floating breakwater, to enhance the marina’s functionality and reduce wave-related issues.
Through harbor measurements and wave agitation modeling using ARTEMIS, IMDC identified the problem and proposed practical solutions, which were then analyzed and calculated.
When evaluating alternatives, a distinction was made between criteria for damage reduction (throughout the year) and criteria for berthing comfort (during the sailing season). Based on ASCE guidelines, which are specifically applicable to marinas, limits were established for significant wave height and horizontal displacement in the longitudinal direction of the vessel (surging).
To minimize visual disruption and optimize integration, a floating breakwater was recommended at the most seaward jetty location to reduce the incoming wave height. Additionally, to mitigate horizontal wave movement at the berths and improve comfort for moored vessels, it was recommended to deepen the areas beneath the jetties to the depth of the shipping channel.
For the project an adaptation to ARTEMIS was implemented, which allows the transmission of wave energy through permeable structures. This adaptation was presented in a paper at the TELEMAC User Conference.
