Easily manage the difficult profile recording with the helicopter in the usually strong surf area. A very elegant solution. (00092012)

Description: Richards Bay Harbour/Natal/South Africa

Sounding with helicopter in the surf zone

Immediately prior to the start of construction on the north breakwater a profiling (sounding) was taken by helicopter over the entire width of the sole later riprap. For this purpose a rare day was awaited with little surf waited and recorded the profile especially in the surf. The swell waves on the east coast of South Africa are enormous and can swell to a great height. The breakwaters are situated in an area which has one of the strongest breakers on the earth. Even the sea manual warns very strongly about the sea breakers here. Basically this situation is encountered the whole year round.
