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 ...

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),...

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...

Because of problems with the design guidelines produced by PIANC for armoured slopes under attack by bowthrusters, additional work has been done in the Netherlands. On the basis of this work computational rules have been developed. However, because of the increase of bowthruster power, more detailed knowledge is needed on the effect of a...

In dit rapport is getracht op een inzichtelijke en realistische manier de economisch optimale elementdikte van een steenzetting te bepalen. Dit is gebeurd op probabilistische wijze, aan de hand van het bezwijkmechanisme "Instabiliteit van de elementen in de toplaag" Dit bezwijkmechanisme houdt in dat onder bepaalde condities elementen in de...

Bij het bepalen van de sterkte van een dijkbekleding wordt tot nu toe uitgegaan van een losliggend blok als ondergrens voor de stabiliteit. In dit rapport wordt een steenzetting als een ligger beschouwd, waarbij er een normaalkracht opgebouwd wordt, die voor een aanvullende sterkte van de bekleding zorgt. De mate waarin dit gebeurt, is...

Dit artikel behandelt het deelonderzoek naar de sterkte van de glooiingen van de Oosterscheldediiken onder invloed van geconcentreerde golfaanval. ln dit artikel wordt naast de vastelling van een aantal parameters, met name de vaststelling van het berwijkmodel van een glooiing belicht. De geconcentreerde aanval (lange tijd op een vast niveau) is...
