(author)This report investigates how embankments in Bangladesh could be upgraded with no or limited footprint increase. Many Bangladesh embankments need to be upgraded to improve flood protection. Traditionally, embankments are upgraded by adding more soil, heightening the crests while simultaneously widening the embankment maintain slope stability.<br/...report 2023

van Berchum, E.C. (author), de Vries, P.A.L. (author), de Kort, R.P.J. (author)The Galveston Bay Area is under significant risk from hurricane induced flooding. Ever since Hurricane Ike caused billions of damage back in 2008, the option of closing off the Galveston Bay from the Gulf of Mexico was investigated. This report, commissioned by Texas A&M University in Galveston, explores the opportunities and options for the...report 2016

Schaafsma-Tilstra, M. (author)Dikes are part and parcel of the Netherlands. Down through the centuries they have played a role in every attempt to make this country inhabitable in the reclamation of peatland and marshland, as coastal embankments and to enclose polders and flank rivers. This means they are often cultural heritage features of the highest order as they have...report 2014

Zhao, G. (author), Visser, P.J. (author), Peeters, P. (author)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...report 2014

Tettero, M. (author)The Netherlands is not well protected against flooding and limited budget it available for improvements. Therefore, this research investigates in what way the cost-effectiveness of Dutch flood protection can be improved with the use of multifunctional unbreachable dykes. The multifunctional unbreachable dyke, a dyke combined with additional user...report 2013

Van Esch, J. (author)This report assesses the consequences of droughts and periods of heavy precipitation for embankments. The proposed assessment procedure couples an agro-meteorological model based on the Penmann-Monteith expression to a groundwater flow model based on Dupuit's approximation. This approach is justified by the fact that the flow process through the...report 2012

Gier, F. (author), Mönnich, J. (author), Schüttrumpf, H. (author), Van der Meer, J.W. (author)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...report 2011

It adds information from three specific case studies (the Netherland, New Orleans and Vietnam) to the global study. The case study areas are comparable by type of coast; all are low-lying deltaic coastal areas. This study investigates the unit cost...report 2010

Husrin, S. (author)Results showed that the existing model on erosion of clay with water-filled cracks (Führböters theory) which only considers cohesion as the soil strength is only applicable for certain conditions. The model should consider other resistant forces such as soil weight and pore pressures. From the tests on clay without water-filled cracks, it...report 2009

Piontkowitz, T. (author)A large number of the dikes in the North Sea and Baltic Sea regions are covered with grass that is exposed to hydraulic loading from waves and currents during storm surges. During previous storm surges the grass cover layers often showed large strength and remained undamaged. A clear physical understanding of the failure of grass cover layers...report 2009
