Abstract [en]

Correct scaling of breach analysis of river levees is a challenging task that is not easilyaccomplished by physical modelling. Several small-scale physical model tests have been conducted at 1-glevel, which cannot truly represent the stress-dependency of soils, whereas the scaling issues arising fromcentrifuge modelling have not been fully explored.Two key features have to be considered whenmodelling the prototype behaviour. On the one hand, the whole embankment should be included in themodel to ensure that flow nets are valid. This is not always easy to achieve due to space limitations withinthe strongboxes used. On the other hand, full control of water levels, prior and during breaching, is ofprincipal interest.This contribution shows how both of these features can be modelled for levee breachingby taking advantage of the availability of space within a drum centrifuge and its versatile toolplate.
