Impact Modelling of Hurricane Sandy on the Rockaways: Relating high-resolution storm characteristics to observed impact with use of Bayesian Belief Networks

Hurricane Sandy (2012), which made landfall in New Jersey on October 29th, made devastating impact on the East Coast of the USA and struck major parts of New York City, including the economic centre of Manhattan. The total damage (in the USA and Caribbean) is in excess of 100 billion US$ with estimates ranging between 78 and 97 billion US$ for...

Bed level changes in the Waal during floods

Bed level changes during a flood can have large influence on the safety against flooding and the navigational function of a river. In 1997 measurements were carried out in the Waal during a flood. These measurements present an average decrease of the bed level in the order of 10 cm over a 10 km reach which is much larger than expected from the...

Design of a breach retardant dike

Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...
