Bruins Slot, Hilco (author), Nugteren, Alex (author), van Rie, Victor (author), Nota, Hugo (author), Overgaauw, Tim (author), van der Heide, Niels (author)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...student report 2020

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...master thesis 2016

La Gasse, L.C. (author), Van Rooij, M.I.S. (author), Smits, B.P. (author), Ton, A.M. (author), Velhorst, R.L.C. (author)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...student report 2015

Hai, T.L. (author), Verhagen, H.J. (author)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...conference paper 2014

Arecco, P. (author), Li, Y. (author), Miranda Eguez, C. (author), Ruiz Fuentes, M.J. (author)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 ...student report 2013

Jassim, I. (author), Tan, S. (author), Vermeer, P.A. (author), Hicks, M.A. (author)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...conference paper 2012

Dorst, K. (author), Provoost, Y. (author), Verhagen, H.J. (author)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...conference paper 2012

Verhagen, H.J. (author)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...conference paper 2012

Klein Breteler, M. (author)In het kader van de toetsing van de waterkeringen zoals voorgeschreven in de Waterwet dienen ook steenzettingen elke zes jaar getoetst te worden. Om de toetsing te vereenvoudigen is door Rijkswaterstaat in 2006 het initiatief genomen om een computerprogramma te laten ontwikkelen dat al het rekenwerk en de beoordelingen uitvoert. Er is gekozen...report 2012

Voor het meewegen van een variërende golfhoogte gedurende de belastingperiode zijn er twee methodes vergeleken. Om de twee methodes goed te kunnen vergelijken is de werkelijke...report 2012

Den Bieman, J. (author), Van den Koppel, M. (author), Van Velzen, G. (author), Verbruggen, W. (author)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...student report 2010

Sluijsmans, R.W. (author)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...master thesis 2009
