A lot of industries in the world use water and produce waste, and with limited water resources and an increasing population, industrial development has grown, putting even more stress on resources. This issue of concern has been recognized and efforts into conserving these precious resources has been …

From previous research in the western Wadden Sea it is clear that mussel plots are important hotspots for biodiversity. When the density of a mussel plot is higher, the biodiversity appears to be higher as well. This final thesis project was a part of the bigger project, ‘Added value with Mussels’, executed …

Nutrient enrichment, scientifically known as eutrophication, is a worldwide problem. Eutrophication is one of the main drivers for cyanobacteria blooms. Cyanobacteria blooms can have a negative effect on ecology, economy and human health, as a result of to the ability of some species to release toxins. …

De intergetijdengebieden van de Oosterschelde worden bedreigd door zand honger problematiek. De aanleg van mosselbanken kunnen een zelf-onderhoudende, duurzame, geïntegreerde, en kosteneffectieve oplossing zijn voor dit probleem. Echter, de mosselbanken in de Oosterschelde nemen af. Voor het creëren …

Water velocity in rearing units for Atlantic salmon post-smolt can influence fish robustness. Studies have shown that training at velocities between 1-2 body lengths/second (bl/s) increases disease resistance in salmonid species. Monitoring and timely adjustments to the water velocity during post-smolt …

Eutrophication because of heightened phosphorus and nitrogen input into freshwater ecosystems is an increasing problem, while at the same time phosphorus availability for agricultural purposes is decreasing on a high pace. B-Ware Research Centre and Radboud University Nijmegen developed a novel biocascade …

Population size increase at the Balgzand intertidal in the western Dutch Wadden Sea suggested a growth decrease in both plaice and flounder populations over summer. Research into the seasonal growth of 0-group plaice, Pleuronectes platessa, confirmed this suspicion. The years 1995 and 1996 had contrasting …

De Europese zeebaars (Dicentrarchus labrax) heeft een commerciële waarde. Toch is nog maar weinig informatie beschikbaar over de demografische geschiedenis, patronen en de geografische verspreiding van de zeebaars in het noordoostelijke gedeelte van de Atlantische Oceaan (Coscia & Mariani, 2011). De …

This study aimed to get more insight into the habitat use and distribution of three sandeel species (Ammodytes sp. & H. lanceolatus) in the Voordelta and describes the findings regarding the Voordelta as a transitional habitat for sandeel populations. As compensation for loss of habitat and foraging …

Het doel van dit project is om de Sleutelfactoren voor gezond stedelijk water, waar Deltares aan werkt verder uit te werken en toe te passen in de stad Utrecht. Met deze methodiek kunnen op structurele wijze functie-doelstellingen worden opgesteld voor stedelijk water die specifiek gerelateerd zijn aan …
