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...

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...

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...

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...

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...

This report is a compilation of facts and information that summarizes the present state of knowledge related to wave attack on the flood side of earthen levees. Particular emphasis was placed on the need for providing flood-side armoring (beyond the protection afforded by grass) for the New Orleans Hurricane & Storm Damage Risk Reduction System ...

The US Wave Overtopping Simulator has to simulate overtopping discharges up to 2 cfs/s/ft for wave conditions of respectively 8 ft with a peak period of 14 s and 3 ft with a period of 6 s. This requires a Simulator which is in size about three times larger than the existing Dutch one. This report describes the theory of waves overtopping the...

Results showed that the existing model on erosion of clay with water-filled cracks (Führböter’s 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...

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...

Na 75 jaar is de Afsluitdijk toe aan en flinke opknapbeurt, concludeert het kabinet in de Watervisie uit 2007. Het kabinet wil weten of er, als er dan toch opgeknapt moet worden niet méér kan. Of een betere veiligheid te combineren valt met bijvoorbeeld natuur, duurzaam opwekken van energie of betere verbindingen voor wegverkeer en scheepvaart....

The Climate Dike is a logical addition to the current practice of raising and reinforcing dikes. A Climate Dike is defined here as „a collective term for design components that result in flood defences so robust that they are virtually impossible to breach, and thus offer lasting protection, even in the face of ongoing climate change.. The...

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...

In the low-lying coastal regions coastal defence structures are usually designed with a main function to protect the hinterland from highly vulnerable to coastal flooding. Sea dikes are usually the most common and important elements which form the coastal flood defence system. Sea dikes are designed at a pre-defined circumstance and requirement....

The ‚Guidelines and Recommendations for the Design of Coastal Structures (EAK)‘ published in 1993 (Die Küste, H. 55) have been revised based on today’s scientific knowledge, technical development and practical experience of the past years. Major parts of the recommendations have been re-written. Together with the unmodified recommendations, D, E...

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...
