Monitoring and research
Wilt u weten hoe hard het stroomt op uw projectlocatie? Hoe hoog de golven zijn of hoe dynamisch de zeebodem? Wij voeren hydromorfologishe metingen uit om de fysische omstandigheden van uw projectlocatie nauwkeurig in kaart te brengen.
Onze metingen
Wij voeren metingen uit naar onder andere de volgende hydromorfologische parameters:
- Stroomsnelheid en -richting
- Debietmetingen
- Golfhoogte en -richting
- Zandtransport
- Sedimentsamenstelling
- Waterkwaliteit
Uitvoering
Wij hebben een uitgebreide set aan eigen hydromorfologische meetinstrumenten:
- Acoustic Doppler Current Profilers (ADCP’s) en Velocimeters (ADV’s)
- Golfboeien
- Drukdozen
- Multi-Parameter Probes (MPP’s)
- Diverse meetvissen voor profielmetingen en bemonsteringen in de waterkolom
Wij plaatsen onze instrumenten in meetframes op de zeebodem of integreren ze in meetboeien en meetpalen. Voor de planning en voorbereiding vertrouwen wij op onze jarenlange ervaring met het uitvoeren van dit soort metingen. Omdat wij de meetdata vaak zelf gebruiken voor de validatie van onze modellen, weten wij precies welke meetdata nodig is om uw vraag te beantwoorden. Wij meten niet om het meten, maar om te weten.

Effects of Dredged Material Disposal in the Eems
The navigational channel between the Eemshaven and the North Sea needs to be dredged regularly to remain accessible to seagoing vessels. The dredged sediment is disposed of at various disposal sites, which may have an impact on the local ecology. To assess these effects, flow conditions and sediment concentrations were measured at a disposal site during sediment disposal operations. Based on these measurements and a numerical modelling study, WaterProof assessed whether sediment disposal at location P0 could have significant adverse effects on the ecology.
Research into Scour Pits
Offshore wind farms use different types of foundations depending on the site conditions. The most commonly used foundation types are monopiles, gravity-based structures and jacket foundations. In collaboration with Leo van Rijn, WaterProof investigated the expected dimensions of scour pits around offshore wind turbine foundations. The study combined physical scale experiments carried out in WaterProof’s flow and sediment basin with numerical modelling.
Impact of EMF and Underwater Sound on Harbour Porpoises
Export cables are used to connect offshore wind farms to onshore substations, from where the electricity is fed into the national power grid. Electromagnetic fields (EMF) are generated around buried export cables as a result of the electrical current flowing through them. These EMF may potentially affect marine life. The magnitude of these fields and their potential impact are still largely unknown. We therefore work with several partners on different measurement and research projects to better understand and assess these effects. Research into the potential relationship between EMF and harbour porpoise presence within the Borssele offshore wind farm is one example.
