Rijkswaterstaat, part of the Dutch Ministry of Infrastructure and the Environment is developing a model for IJmuidens outer harbour. The North-Holland Department of Rijkswaterstaat organised two 13-hours measurement campaigns to gain calibration data for the model. The measurements involved current and sediment concentration measurements with an ADCP and profile measurements of turbidity, temperature and salinity. All data were acquired using ViSea DAS and the Plume Detection Toolbox.
