In 2012 verloren we Jean Jacques Peters, voormalig ingenieur van het Waterbouwkundig Laboratorium (1964 tot 1979) en internationaal expert in sedimenttransport, rivierhydraulica en -morfologie. Als eerbetoon aan hem hebben we potamology (http://www.potamology.com/) gecreëerd, een virtueel gedenkarchief dat als doel heeft om zijn manier van denken en morfologische aanpak van rivierproblemen in de wereld in stand te houden en te verspreiden.
Het merendeel van z’n werk hebben we toegankelijk gemaakt via onderstaande zoekinterface.
A new field overtopping tank at the breakwater of Ostend

In Ostend a field overtopping tank has been constructed on the eastern harbour breakwater. As the crest level of the breakwater is rather low compared to the mean water level, wave overtopping over the breakwater occurs quite frequently. By measuring instant water level into the overtopping tank, it is possible to determine the volume of water overtopping the breakwater. Mean overtopping discharge as well as individual overtopping volumes per wave can be determined. A video recorder installed on top of the radar tower on the breakwater allows to film overtopping events. By comparing these images taken at specific moments with the measured overtopping volume at that time, a better insight is gained of how a specific overtopping volume looks like.
The intention of this field overtopping installation is to get a better insight into the mean and individual overtopping quantities being dangerous for people. In the specific case of Ostend, this will allow to judge better when the promenade on the breakwaters should be closed for people because the overtopping leads to a dangerous situation. More general this research will allow to quantify the effect of a specific overtopping volume for people.
