11 December 2010. Sunset, with a pleasing view, at the end of the video, of volcano Etna (Sicily).
New video: high waves in the natural ocean engineering laboratory NOEL of Reggio Calabria, during an experiment on hydrodynamic forces of sea waves on horizontal submerged cylinders (tunnels of pipelines). A submerged cylinder is supported by the structure shown in the picture. It is possible to see two ultrasonic probes which record the free surface displacement . The force on the cylinder is recorded by means of eight pressure transducers in the vertical mid section of the submerged cylinder.
