Volbeda, E.A. (author)
Bank protections are currently constructed with stone, wood, concrete and steel. NETICS has introduced a sustainable and commercially very attractive alternative called the GEOWALL. The goal of this study is to find a viable field of application within the quay structures by considering the arising challenges of a larger scale wall. Additionally...

This report presents a study of the Malecón Tradicional in front of ‘Centro de Havana’ and ‘Havana Vieja’ in the city Havana, Cuba. The objective is to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Implementing the recommended solutions reduces the overtopping sufficiently...

Many dike failures have been ignited by damage due to erosion on the landward slopes. This paper investigates how grass covered slopes perform when being attacked by overtopping flow during storm surges. Based on observations during a number of simulator tests, damage is classified into three types 'head-cut', 'roll-up' and 'collapse' depending...

The Afsluitdijk (Enclosure Dam) is a major causeway in the Netherlands, which was constructed between 1927 and 1933, running from Den Oever on Wieringen in North Holland province, to the village of Zurich in Friesland province. The dam is 32 kilometers long and 90 m wide, with an initial height of 7.25 m above sea-level and a slope of 1:4 ...

The numerical simulation of wave attack on a sea dike with an asphalt concrete revetment during a severe storm is carried out using the dynamic Finite Element Method. When wave loads attack the revetment during such a storm, both the revetment and the underlying soil may be damaged. The two-phase flow equations are considered, to study the...

A revetment of pattern placed elements, or a so called pitching, is used worldwide to protect shorelines and embankments. Also in The Netherlands more than 500 km of river, lake and sea dikes is protected by pitchings. Until the 60’s the design and construction of pitchings was based on experience. After the first damages on pitchings and the...

Apart from many ecological advantages, mangroves in front of a coastal defence may lower the construction and maintenance costs of the defence. Although mangroves have hardly any reducing effect on water levels (and on tsunami impact) mangroves may significantly reduce wave attack on a coastal dike, and in this way reduce the cost of a revetment...

One of the branches of the Paraná delta is the Paraná de las Palmas River. This branch doesn’t have the biggest discharge but has the most navigation. The situation in the Paraná de las Palmas isn’t without problems though; the river banks show erosion over the whole length of the branch. This erosion has been investigated by the following...

A new construction method of Polyurethane (PUR)-bonded revetments has been tested successfully on various locations in Germany, in the Netherlands, in France, and in the UK. See also the presentation of Bijlsma on this ICE breakwater conference. This year a series of large scale test in the GWK-facility in Hannover have been executed. This...

The elastocoast system can be used as an armour layer on revetments. The bonding system exists of a mix of crushed stones and 2-component polyurethane. This bonding system creates bonding forces between the stones and an open (porous) structure can be obtained. Elastocoast is developed by Elastogran GmbH, a BASF subsidiary. The response of an...

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...

A new construction method of Polyurethane (PUR)-bonded revetments has been tested successfully as stable breakwater constructions on various locations in Germany (“Hamburg Hallig”, “Holm Gröde”), as dike revetment in the Netherlands (breakwater revetment in Zuidbout and Petten), as shoreline protection in France (canal embankment near Le Havre),...

Elastocoast is a new type of revetment system for use as a cover layer on dikes. It consists of granular material (rocks), which is fixed together with a two-component polyurethane adhesive. In the Elastocoast system each individual rock is covered with a thin film of polyurethane. When the adhesive is cured, this film fixes the rocks together...

Bijlsma, E. (author)
In September 2007 two prototype pilot tests were constructed along the Dutch coast with an experimental, polymer based revetment. An area of 490 m2 was put on a dike slope in the Eastern-Scheldt basin, and another 385 m2 on the horizontal surface of a beach groyne near the Pettemer Zeewering along the North-Sea coast. The revetment consists of...

PUR-revetment is a newly developed method for hydraulic application. Its structure is similar to that of open stone asphalt revetment, but the crushed stones are glued by polyurethane (PUR) instead of bitumen. To study the feasibility of applying PUR-revetment, a research based on the comparisons between PUR-revetment and open stone asphalt...

Environmental awareness and sustainable development have been popular themes over the last few years. To improve dikes along the estuaries in Zeeland (The Netherlands) where a high foreland with natural areas of salt marshes is present, alternatives to stone revetments are examined. From a natural and aesthetic point of view, a slope covered...

Het onderzoek beschrijft de trekproeven en schuifproeven die in het veld zijn uitgevoerd ter verificatie van het liggermodel voor geklemde steenzettingen. De proeven worden in Zeeland uitgevoerd. Er is gemeten aan Hydroblocks en Basalton zettingen met resp. 35 en 25 cm zuilhoogte. In totaal zijn er 61 trekproeven en 11 schuifproeven uitgevoerd....
