New Beach at 1/30 for HEXECO Project

Equipment:

  • Large wind tunnel - water simulation of oceanic interactions - atmosphere (40 m x 3 m x 1.5 [EW3] water depth)
  • 18 m wave canal (0.65 [EW4] wide and 1.5 m tall). This canal is made of glass and can be raised to allow for viewing from underneath.
  • The GIS-HYDRO hydrologic modeling tool (ECM IRPHE ISITV) is a part of a grant from the Var Department to conduct experimental research in the BGO-First ocean engineering basin and is located in Seyne sur Mer, France.
  • HEXAPOD

Measurement Tools:

  • Laser and hot wire velocimetry
  • Hot-film velocimetry in water
  • Wave probes
  • High frequency radar
  • 2D and 3D visualization systems
  • Effort sensors
  • Pressure meter
  • PIV and continuous laser system
