Background
Wave water tank model test of breakwaters (including seawalls and breakwaters) is one of the most important research contents of the overtopping amount of the top of the breakwater. The overtopping amount is called as the single-width average overtopping amount, and refers to the unit water receiving width and the overtopping water amount in unit time under the action of 1 wave train (usually more than 120 waves), and is generally measured by adopting a manual weighing method. In the traditional test process, a measurer needs to enter a wave water tank to stand behind a test breakwater, a water receiving barrel is held by hands, the water receiving barrel is arranged on the top of the breakwater through a thin plate, the wave-crossing water body crosses the top of the breakwater and enters the water barrel along the thin plate, after a group of tests are finished, the experimenter moves the water barrel out of the wave water tank, then pours water into other containers and weighs, and the single-width average wave-crossing amount is converted according to weighed data.
In the traditional test method, the manual participation is excessive, obvious accidental errors exist, and for the small wave-crossing test group, for the same group of tests, different measurement personnel have relatively large difference of the wave-crossing measurement results with smaller absolute values due to the difference of operation habits and operation modes; for the large wave-crossing test, the operation difficulty of manual water receiving and transferring is large due to the limited water receiving space, and the bucket is easy to shake violently due to secondary waves after a large amount of wave-crossing water bodies cause the dike. The seawall is the main facility for preventing tide and waves in estuary and coastal areas, however, under the condition of encountering extreme storm surge, erosion and damage of the back slope of the seawall often begin from violent scouring under the action of single large wave. The single-width average overtopping amount measured by the traditional test method is only a numerical value with an average concept in a time range, and the overtopping amount and the change rule thereof under the action of a single wave cannot be obtained.
