The Reeuwijkse Plassen have been dealing with a declining water quality for the past century. One of the problems is eutrophication due to in- and outflow of nutrient rich water from surrounding areas which caused algae blooms and turbid waters. The waterboard Hoogheemraadschap Rijnland implemented measures …

Spatial and temporal patterns in submarine groundwater discharge (SGD) of nitrate in a high-energy sandy beach system on Spiekeroog Island were examined utilizing UV photometry. SGD as pathway of nitrate was studied to gain better understanding of the variability of nitrate discharge and the factors …
