Puerto San Vicente, Chile: Evaluation of a Port Expansion

This report is written with the aim to evaluate a possible port expansion in the port of San Vicente, Chile. In order to achieve this a thorough analysis on the port operations, hydrodynamical analysis using Delft3D and a bottleneck analysis on the infrastructure have been executed. A preliminary design for the port expansion is created. This...

GEOWALL® as a Quay wall

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...

Coastal protection Malecón seawall: A study to develop a sea defence solution that prevents unacceptable flooding and damage to the 'Malecón Tradicional' in Havana, Cuba

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...

Afsluitdijk upgrading, non typical Dutch solutions

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 ...

Erosion of river banks along the Paraná de las Palmas River, Argentina

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...

Analysis of wave impact on the elastocoast system

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...

The Elastocoast® system: A study of possible failure mechanisms

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...

Elastocoast pilots in the Netherlands, storm season 2007/2008

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...

A clay layer as a revetment for sea dikes: The behaviour of clay under wave loading

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...

Veldproeven op steenzettingen in Zeeland: Eindrapport met resultaten en analyse van onderzoek naar de klemming van gezette stenen

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....

Een probabilistisch ontwerp van een steenzetting

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...

Stabiliteit van steenzettingen: Beschouwing van een dijkbekleding als een verend ondersteunde buigligger

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...
