Maritime constructions are very complex to design because at the borderline between hydraulics and geotechnics. The interaction between wave impact and beach erosion or breakwater design is generally described by complex engineering tools and developments and needs a lot of experience. AquaVision engineering is one of the leading Swiss companies in this field, offering sound experience in the following project areas: - design of shoreline protection works (groynes, breakwaters, etc.) - design and stabilization of beaches - design of harbors and harbor entrances - wave formation, propagation and impact on shorelines and harbors - waves inside harbors- undermining of coastal protection works by wave impact
