WebMar 31, 2024 · The breach was triggered by overtopping the dike crest. A detailed monitoring of the transient evolution of the breach geometry was conducted, providing key insights into the gradual and complex processes involved in fluvial dike failure. The breach develops in two phases: (1) the breach becomes gradually wider and deeper eroding on … WebAccording to Johnson and Illes (10), the breach geometry is directly related to the duration and shape of the overtopping flood wave. They state that the typical breach is between one and three times as wide as it is deep. However, no documented research exists to relate breach geometry to breach hydraulics.
