In light of recent developments of the onboard ballast water treatment, WMR has developed a new protocol for the assessment of ecotoxicological effects and aims to use it as a standardised test. This study looks into the validation of this short-chronic ELS fish toxicity test, by use of the embryonic …

Stormwater runoff has severe negative and direct impact on the quality of surface waters and groundwater. The impact can cause chemical and heavy-metal pollution. Applying well established methods to map pollutants in urban areas and specifically in Nature-Based Solutions (NBS), such as Sustainable Urban …

Due to climate change the frequency of extreme precipitation increases. To reduce the risk of damage by flooding, municipalities will need to retrofit urban areas in a climate-resilient way. To justify this investment, they need insight in possibilities and costs of climate-resilient urban street designs. …

The changing climate has an effect on the quality of life in our cities: heavier rainfall (resulting in floodings), longer periods of drought, reduced air and water quality and increasing temperatures in cities (heat stress). Awareness about these changes among various stakeholders is of great importance. …

Urban water bodies like ponds or canals are commonly assumed to provide effective cooling in hot periods. Some of the evidence that feeds this assertion is based on remote sensing observations at relatively large scales. Such observations generally reveal reduced surface temperatures of water bodies …

The seeding of mussel seeds is an important factor within the mussel culture as losses can be as high as 75% within the first 4 weeks after seeding. Therefore it is important to get more knowledge about the factors that can cause mortality within the first weeks after seeding. With seeding high local …

Introduction In the harbor of Zierikzee there is a strong tidal influence. The difference between the water levels during high and low tide lies around the three meters. The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …
