Morphological development after the July 2014 flow slide on the tidal flat of Walsoorden in the Western Scheldt

The overall behaviour of the tide-dominated Western Scheldt is in general well known. Its multichannel-system consists of ebb and flood channels, separated by intertidal areas; the tidal flats. The estuary shows a dynamic behaviour of erosion and sedimentation of the tidal flats. A large flow slide occurred at the tidal flat of Walsoorden in...

Flow slide failure of excavated subaqueous slopes

Unexpected failure of subaqueous excavated slopes in the form of flow slides is considered in this graduate study. Excavated slopes are not the same as slopes constructed by means of hydraulic fill. Several recent flow slide failures in sand borrow pits, together with qualms in engineering practice about not knowing exactly what fundamental...
