Hydrodynamics Laboratory and Wave Flume

ACRI-IN has a hydrodynamics laboratory equipped with a wave flume. This allows us to complete test programs on physical models, as part of our primary marine and port engineering, for structure sizing studies (rubble mound breakwaters, wave absorbing quays, etc.), as well as for more specific R&D efforts.
We also complete studies as a subcontractor to competing companies, as such equipment is rare among specialized engineering companies in our field.


  • Canal measuring 31 m x 1.80 m x 2 m including 2 square inspection windows measuring 1.50 m x 1.50 m for observation
  • Regular and spectral wave generator
  • Adjustable mobile platform to reproduce any 2D bathymetric profile
  • Recirculation flow with current generator for experimental studies on hydrodynamics (R&D)


  • Processing measurements and developing specific tools using MATLAB
