The northwestern winds have generated large waves, that hit the Sand Motor with a lot of power during the storm. The Turbulence Rig is the most seaward located frame that was installed, so it catches the largest breaking waves. The frame is equipped with a velocity meter, suspended sediment sensor and a sonar for the bottom profile. The rig was anchored in the sand with three large poles, but due to the storm a lot of sand washed away and one of the poles got undermined by the waves. The rig toppled and the other poles bended. The rig lay flat on the seafloor. In the evening our technician Henk helped us to save all the equipment. Below a picture of the Turbulence Rig Rescue Team, and the frame which is saved.
Due to the storm the beach profile has changed. During the calm and sunny weather earlier this week, the profile was relatively steep with a high intertidal bar. At the time of the storm strong currents are found between the intertidal bar and the swash zone. In the channel dunes have developed. Today almost all dunes are gone and the beach has flattened.
