  1. 1. Prototype measurements of wave interaction with Zeebrugge rubble mound breakwater <ul><li>Cross-section of the Zeebrugge breakwater with measurement jetty, and position of prototype instruments (buoys, radar, stepgauges, pressure sensors) </li></ul>Example of measured structural response: waves run up on the breakwater slope with associated infiltration and pore pressure attenuation (in core), and overtopping (over crest)
  2. 2. Wave flume for physical modeling The physical wave flume (dimensions 30m x 1m x 1.2m (L x W x H)) is constructed from reinforced concrete, with a glass side-wall (15m) in a steel frame. Waves are generated using a piston-type paddle. The maximum wave height in the flume is 0.35m. Active wave absorption is installed . Example: hydraulic stability tests using a physical scale model of a rubble mound breakwater armoured using HARO ® armour units. (model scale = 1/40)
  3. 3. Numerical simulation of wave interaction with coastal structures <ul><li>Simulation of wave interaction with a rubble mound breakwater, showing wave run-up, infiltration and seepage, and pore pressure attenuation [using Navier-Stokes equations and VOF-method] </li></ul>Simulation of irregular waves propagating and penetrating the harbour area, as a result of wave diffraction, refraction, shoaling and breaking [using non-linear Boussinesq wave equations]
  4. 4. Instrumentation for laboratory and in the field <ul><li>Particle Image Velocimetry </li></ul><ul><li>Optical measurement technique for spatial velocity fields in highly turbulent flows, </li></ul><ul><li>using laser sheet and digital camera for capturing the movement of the tracer particles in the flow </li></ul>Profiler Optical measurement technique for development of damage profiles e.g. for design of bottom erosion protection around wind farm turbines (situation before (top) and after (bottom) a storm ) Wave run-up gauge Digital stepgauge mounted on rough slopes (lab and field) for accurate measurement of wave run-up height
