Hughes, S.A. (author)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 Centers Coastal and Hydraulics Laboratory in Vicksburg, MS. The purpose of the physical model was to obtain hydrodynamic measurements of unsteady flow...report 2008

Verhagen, H.J. (author), Jaspers Focks, D.J. (author), Algera, A. (author), Vu, M.A. (author)Vetiver grass is a sustainable and innovative solution for the protection of banks. It is shown that Vetiver grass is able to establish a full-stop of bank erosion caused by rapid drawdown. Therefore it provides us with strong indications that it is highly suitable as an anti-erosion measure. A combination of cohesive soil and Vetiver grass...conference paper 2008

Pullen, T. (author), Allsop, N.W.H. (author), Bruce, T. (author), Kortenhaus, A. (author), Schüttrumpf, H. (author), Van der Meer, J.W. (author)The manual has been intended to assist engineers who are already aware of the general principles and methods of coastal engineering. The manual uses methods and data from research studies around Europe and overseas so readers are expected to be familiar with wave and response parameters and the use of empirical equations for prediction. Users...report 2007

Verhagen, H.J. (author)Dike design is a very traditional craft. Since many generations dikes have been constructed in our part of Europe. After each disaster the dike was rebuilt, and improved. The improvement was always based on the experiences of the previous flood. For example, for many years the design height of a dike was determined as the height of the highest...conference paper 2007

van Gerven, K.A.J. (author), Akkerman, G.J. (author)The present report deals with the application of a provisional Smart Grass Reinforcement (SGR) system in 2006 for full scale testing of increased overtopping at the Groningen sea dyke test section near Delfzijl, as envisaged in 2007. The SGR has been placed at two strips of 4 m wide: one primary strip at the basic test site and one at a...report 2007

Akkerman, G.J. (author), van Gerven, K.A.J. (author), Schaap, H.A. (author), van der Meer, J.W. (author)In the present report field erosion tests of the inner slope of a sea dyke in the province of Groningen (near Delfzijl) are described for the situation of severe wave overtopping. Three types of tests have been performed: tests at the present grass cover, tests at a reinforced grass cover and tests at a section of bare clay. At the reinforced...report 2007

Van der Meer, J.M. (author)The wave overtopping simulator is a device which is able to simulate overtopping waves at the crest of a dike and at the inner slope. The device has been used in the ComCoast project to test a traditional dike section with grass and the SGR, the Smart Grass Reinforcement, placed in May 2006. This report describes in the first part (Chapters 1-6)...report 2007

Salter, S. (author)It is now accepted that the combination of more intense rainfall, poor planning of built-up areas, rising sea levels, coastal erosion and, in particular, higher storm surges pose a real threat to the UK and many other countries.

ComCoast (author)A desk study has been carried out in order to develop a conceptual model for the erosion of inner dike slopes with reinforced grass cover. Based on the results the following can be concluded: The presence of a geosynthetic in a grass slope can be taken into account in the EPM method by increasing the critical flow velocity. In particular, a...report 2005

Pilarczyk, K.W. (author)As a low-lying and highly developed country, the Netherlands is continuously facing potential flooding disasters. Thats why we need strong safe water-retaining structures like sea and river-dikes. Moreover half of the country lies below mean high water level. Without dikes more than half of the country would be endangered by flooding. About 60%...report 2003
