Overtopping over a dike
Demonstration of 0.1, 1 and 10 litres overtopping over a grass dike. Tests from TAW in WL-De Voorst, with sound (in English). play at “full screen” to avoid distortion.
Waves on a slope
Overview of waves at the coast of Scheveningen; shot from the breakwater, refraction is clear. At2:00 details from breakwater. At 2:30 models tests on a slope; plunging breakers in lab, including some slowmotions and stills. At 4:16 oblique view of the flume (from 4:50 to 7:40 one wave in extreme slow motion; shows runup and rundown in detail), shot repeated in normal speed. At 8:44surging waves against 1:1.5 slope of tetrapods; shows limitation of runup.
Standing waves
Demonstration of standing waves over a rock bed.
Standing waves with lumps
Slow motion shots of a demonstration of standing waves with lumps over a rock bed. The lumps show the orbital movement.
