Abstract:The demand for sand from the North Sea used for coastal replenishment and construction sand is expected to grow in the future. In the meantime other user functions such as wind farms, nature, cables and pipes are also expected to grow and will ask for more space in the North Sea. For these reasons, it is expected that the pressure on the available space in the North Sea will grow in the future. Therefore spatial planning in the Dutch North Sea is an important issue. This research focuses on the optimisation of spatial planning and sand extraction from the Dutch North Sea in the future. The objective of this research is to enable optimisation of the available areas for sand extraction in the Dutch North Sea, by developing a tool which determines site specific safety areas around sandpits. This research started by analysing the available area and demand for sand extraction from the Dutch North Sea. Sand demand is analysed, based on the sand demand scenarios developed by Rijkswaterstaat (Dutch department for water, infrastructure and public works). For the available area for sand extraction, a sand extraction location model is developed in ArcGIS. This model generates a map with the locations where sand extraction is allowed and which locations have priority for sand extraction. The model is based on the current common practice and legislation for sand extraction. It is easy to make adjustments in this model if there are changes in legislation. Based on this new legislation it is easy to make a new map.
