Safety Assessment Method of Flood Defences for Flow Sliding

Flow sliding of submerged slopes in front of dikes can affect the reliability of flood defences. The occurrence of flow sliding may result, sometimes with delay, in a failure mode and consequent flooding. The current safety assessment method for flow sliding does not consider the interaction between flow sliding and failure modes which can cause...

Overview geotechnical model tests on dike safety at Deltares

Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed. The three studies use different physical models, depending on the research questions at the beginning...

Large scale sand liquefaction flow slide tests revisited

Massive failure of submerged slopes form a major threat for many dikes along estuaries in the Netherlands, the subsoil of which consists of alternating layers of loosely packed and more densely packed sand. Static liquefaction in the loosely packed sand plays an important role. Insufficient knowledge is available to predict the flow of sand and...
