Experimentelle Untersuchungen zur Stabilität von verzahnten Setzsteindeckwerken

Revetments protect the shorelines of coasts, estuaries and rivers against wind wave, ship wave, current and ice attack. The resistance of revetments essentially depends on the properties of the cover layer. The resistance of interlocked pattern placed revetments depends on the weight of the individual stones and the interlocking. Extensive large...

Wissenschaftliche Untersuchung der Stabilität von Verkalit-Deckwerksteinen

Während des Versuchszeitraums wurden vier verschiedene Modellphasen durchgeführt. Die Modellphasen 1 bis 3 variiteren nur bezüglich der zum Einsatz kommenden Verkalit-Deckwerksteine. Der unterliegende Deckwerksaufbau hingegen stellte mit der Schichtenabfolge Sand, Kornfilter, Geotextil einen nach den Regeln der Technik anerkannten...

Combined Wave and Surge Overtopping of Levees: Flow Hydrodynamics and Articulated Concrete Mat Stability

A 1-to-25 scale physical model of a typical cross section of the levee along the Mississippi River Gulf Outlet (MRGO) was con-structed at the U.S. Army Engineer Research and Development Center’s Coastal and Hydraulics Laboratory in Vicksburg, MS. The purpose of the physical model was to obtain hydrodynamic measurements of unsteady flow...

Design criteria for placed block revetments and granular filters

Design criteria for the coverlayer and filter layer of a placed block revetment are presented. These design criteria were derived on the basis of large scale model tests on revetments and test on granular filters. It is shown that the hydraulic loading in the filter can be described with equations of quasi-stationary flow. General filter...
