In many areas, islands and coastal communities are experiencing increasing problems with sludge from marinas along the Wadden Sea coast. These problems are primarily caused by environmental factors, such as long-term trends, changing morphological conditions and alternative freshwater drainage regimes from the hinterland. Often, part of the problem is a lack of knowledge and insight into the causes. There is no widespread collaboration or knowledge exchange between the various parties involved in dredging and there is no collective long-term vision. However, given the continual morphological changes observed and expected in the Wadden Sea region, this kind of vision is essential. This vision must result in lower costs, improved accessibility and greater coherence and collaboration during the costly and time-intensive studies into solutions. The commissioning parties would like to initiate developments into sustainable and efficient maintenance of marinas.
