Coastal engineering
 Our experience in the field of coastal engineering allows us to deal with very  varied demands concerning littoral studies, coastal structures and their  interactions with marine medium. These are the main theme of coastal  engineering studies :
  • Port agitation studies
  • Marine works dimensionning (dikes, caissons, breakwaters, outlets)
  • Coastal arrangement (artificial beaches)
  • Sea structures behaviour (mooring, breakwaters, wave attenuators)
  • Water quality studies

     ACRIIN owns a large variety of means to realise these studies, as for example :
  • A coastal agitation simulator SIMAC : SIMAC
  • A water quality computation code, TIDAL : TIDAL
  • A general computationnal fluid dynamics code, ANSWER : ANSWER
  • A porous media CFD code, PORFLOW : PORFLOW
  • The hydrodynamics laboratory and the wave flume

    Some of our recent studies :

    One of the profils tested in the wave flume Coastal arrangement in Saint Denis de la Réunion

    This is a project of construction of a mole and a nautical base linked by an artificial sand beach. ACRIIN realised an entire agitation study and tested 3 profiles during wave channel tests. Project description
    Agitation study in Nice harbour

    Study of wave propagation from deep sea to the coast by the use of SIMAC. Actual case simulations and proposal of 2 improvements.

    Private marina in red sea

    Conception of a private marina. Renewment of water studies. Project description
    Improvement of superficial waters quality, ville de Dieppe

    The aim of this study was to quantify residual concentrations of bacterias inside the port ofDieppe and on the whole coast. Several hydrological conditions were tested. Model realised with TIDAL. Project description
