Large scale embankment breach experiments in flume

Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...

Destructive tests with the wave overtopping simulator

Report on destructive overtopping tests executed with the wave overtopping simulator along the coast of Vietnam to investigate the strength of the inner slopes of grass dikes. This report presents measurement and observation results obtained during destructive tests with the simulator in Do Son, Thinh Long and Thai Thuy. After the first chapter,...

Sturende factoren erosie, transport en sedimentatie in stroomgebieden Rijn en Maas

Het Delft Cluster-project Waterkwaliteit & Calamiteiten brengt de toekomstige ontwikkeling van de water- en slibkwaliteit in beeld onder invloed van extreme gebeurtenissen (gerelateerd aan bijvoorbeeld klimaatsverandering en verandering in landgebruik) en door de mens veroorzaakte calamiteiten (zoals lozingsongelukken). Dit rapport is het...

Erosion tests on Hannover clay

Erosie onder een geometrisch open filter

Deze notitie beschrijft de resultaten van een inleidend onderzoek naar de mechanismen van de erosie van de basislaag onder geometrisch open filters. Hierbij wordt in eerste instantie uitgegaan van de beter onderzochte erosie van de bodem van een waterloop zonder beschermende filterlaag. Op basis van metingen van Van Os (1998) in een inleidend...

Meetverslag Bresgroeiproeven Zwin 6 en 7 oktober 1994

Gedetailleerd meetverslag van alle metingen uitgevoerd door de meetdienst zeeland tijdens de dijkdoorbraakproef (breach test) in het Zwin op 6 en 7 oktober 1994

Liquefaction and erosion of mud due to waves and current: Experiments on Westwald Clay

A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...

Aggradation in rivers due to overloading

The problem of aggradation in a river due to overloading is tackled with a mathematical model consisting of a set of one-dimensional (in space) basic equations in which the water motion is assumed to be quasi-steady and the sediment transport is determined by local conditions. Analytical solutions are presented of a linearized simple-wave model,...
