Detailed Zeebrugge Hydrodynamic model
Numerical tool as part of an integral approach
for accessibility and safety studies
www.portofzeebrugge.be
Problem statement:
•Accessibility and safety of the port: Strong ebb and flood currents
-> Limited inbound sailing window for tall ships
•Port maintenance: strong tidally driven siltation of the outer port
-> continuous dredging activities (> 4 MTons/year)
Project description:
•Development of integral approach for future assessment studies
•Numerical 3D model, physical model and simulator studies
Model description
•3D: 185.000 cells, 6 vertical σ-layers
•Resolution: 30m – 200m, Δt = 3sec
•Turbulence model: k-ϵ
•Validation: Meetnet Vlaamse Banken, In situ measurements
(fixed ADCP and sailed transects: MVB, Flanders Hydraulics Research)
Model applications
•Port extension and mitigation assessments
