van Rinsum, Guido (author)Reinforcement measures are applied by water boards during critical conditions in an ultimate attempt to prevent flooding. However, the effect of these measures on the reduction in flood risk or failure probability of the flood defence is often unknown. This research focusses on the effectiveness of grass revetment reinforcement measures applied...master thesis 2018

Rietmeijer, Anton (author)Contrary to a breakwater outer slope, rear-slope revetment does not have to withstand breaking waves. However, generally, an equal dimensioned revetment is used on both the inner- and outer slope. Although with low-crested breakwaters severe overtopping occurs, the application of similarly sized armour on both sides still results in an over...master thesis 2017

Klein Breteler, M. (author)In het kader van het “Vergelijkend onderzoek zetstenen voor dijken” is onderzocht of zetstenen slimmer ingezet kunnen worden bij dijkversterkingen. Doordat de thans leverbare typen zetstenen verschillen in vorm, hebben ze ieder specifieke kwaliteiten. Ze zijn bijvoorbeeld extra stabiel of remmen de golfoploop goed. Dit onderzoek is uitgevoerd...report 2016

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

Kruis, M.C. (author)For centuries dikes in the Netherlands have been protected against wave attack by revetments constructed of pitched blocks. Due to new insights into the behaviour of pitched blocks and increased hydraulic boundary conditions, a significant part of those dikes does not meet the current prescribed standards and safety norms anymore. As a result,...master thesis 2014

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

Van Geer, P.F.C. (author), Van Thiel de Vries, J.S.M. (author), Boers, M. (author), Den Bieman, J.P. (author), McCall, R.T. (author)This paper presents adaptations to the XBeach model aimed at including the relevant processes for the generation of scour holes at the toe of a revetment. Dutch assessment rules for the safety of sea defenses need to be adjusted to cope with a combination of sandy dunes and hard elements. To that end, the XBeach model is prepared to be...conference paper 2014

Kishoen Misier, R.K. (author)Nowadays, in the Netherlands there are about 600 kilometers of asphaltic revetments lying mainly on sea dikes of which approximately 400 km of dike is covered with asphalt concrete [STOWA, 2011]. Asphalt concrete revetments are applied the most and are mostly of older age. Because of the older age it needs intensive care involving periodic...master thesis 2014

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

Van Thiel de Vries, J.S.M. (author)In a situation with a narrow dune, the dune base can be protected with a revetment to reduce dune erosion during extreme events. To quantify the effects of a revetment on storm impact, the functionality of the numerical storm impact model XBeach (Roelvink et al., 2009) is extended to account for the complex morphodynamics around revetments. Here...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
