Maritime hydraulics laboratory

Artelia’s hydraulics laboratory, which is more than 10,000 m2 in surface area, has long experience of working on international projects. Wave flumes and tanks of various sizes equipped with sophisticated management and measuring systems are used for studying the hydro-sedimentary dynamics of coastal areas and estuaries (movable-bed scale models), the stability of maritime structures (breakwaters, quays), the dynamic interactions of fluids and structures, port access channels, shiphandling and ship behaviour at berth.
