Ławniczak, Aron (author)Coastal areas face increasing threat from erosion. The use of coastal protection structures is imperative to counter this. Concrete “armouring” is widely used due to durability and cost-effectiveness. Conventional methods of “armouring” result in habitat degradation and loss of biodiversity. ECOncrete developed Coastalock, an armour unit...master thesis 2024

van Donselaar, Kevin (author)Large parts of the Netherlands lay below mean sea level. An extensive network of flood protection measures is in place to prevent flooding. Periodic safety assessment and reinforcement are required to guarantee a resilient system. Currently, in the Netherlands, an extensive sea dike reinforcement program is underway to meet the safety standards...master thesis 2023

van Heest, Martijn (author)Placed block revetments on dikes are used for the protection of the structure against wave loading. The dimensions of the revetment are determined with empirical relations and design tools. The stability of the design solution needs to be checked by physical flume tests to ensure the safety of the structure. However, these tests can be costly...master thesis 2023

Molenkamp, Auke (author)With the advance of urbanisation in coastal regions comes an increase in armoured shorelines and the destruction of coastal marine habitats. To combat this, ECOncrete Tech Ltd has developed a new eco-friendly armour unit, the CoastaLock. With its ecological advantages proven, its hydraulic performance is still largely unknown. This thesis aims...master thesis 2022

Scheurwater, Bart (author)Witteveen+Bos as part of construction consortium Nautilus, has prepared the design of a sea defence system in Middelkerke. The very shallow water conditions (h/Hm0 = 0.3) and complex geometry of the structure, i.e. a high berm and stepped revetment, caused uncertainties in the usage of the empirical equations from the EurOtop Manual (2018) for...master thesis 2022

Boon, Casper (author)Wave overtopping, in which a wave washes over the crest of a dike and damages its inner slope, is one of the many mechanisms that is found to be responsible for dike failures. As these dikes are generally covered with grass, insight into the erosion resistance of these grass covers against wave overtopping is desired. To assess the performance...master thesis 2022

van der Vegt, Niels (author)Over time, degradation processes might cause damage to pattern-placed revetments. Examples of such damages are missing elements, deformation, and the loss of joint filling. However, little is known about the exact consequences of those damages. Therefore, when damage is observed during an inspection, it is estimated based upon experience what...master thesis 2021

van Dijk, Peter (author)Large areas of the world are protected by flood defence systems. A common part of flood defence systems is a levee with grass cover, with the primary function to protect hinterland against floods. Waveovertopping might lead to erosion of the grass cover, followed by erosion of the inner slope and potentially levee breaching. The wave overtopping...master thesis 2021

Goedhart, Wisse (author)The erosion of the seabed in front of coastal structures induced by waves can lead to multiple types of failure instability or function of the structure. On this topic most research has been done into erosion in front of vertical structures. For sloping structures a knowledge gap exists in the understanding of the processes that lead to erosion...master thesis 2021

Dommisse, Wilmine (author)The main objective of this thesis is to increase the understanding of the effect of shellfish presence on the stability of loose rock revetments and to investigate the possibilities in the design. Pacific oyster (Crassostrea gigas) and blue mussel (Mytilus edulis) presence on loose rock revetments was quantified. C. gigas and M. edulis are...master thesis 2020

Radityo Andjaringrat Adhi, Theo (author)Maturity model has proven to be helpful for an organization to identify its current capability, strength, and weaknesses through maturity levels. These levels are used to rank the various dimension or process of an organization. However, maturity levels only describe a general description of organization capability. The effect of different...master thesis 2019

Zaalberg, Piet (author)OpenFOAM allowed the author to simulate a large number of scenarios in which the influences of cross-shore profile shape, cobble porosity, cobble diameter and layer thickness on wave overtopping were examined. Four validation runs and six simulations to map the sensitivity are compared with data from two physical experiments conducted in the...master thesis 2019

Radityo Andjaringrat Adhi, Theo (author)Maturity model is widely known as an assessment tool to understand an organization management capabilities and identifying potential improvement. The model demonstrates informative results towards the organization management maturity but hard to acknowledge the influence of potential improvement towards the organization’s asset performance....master thesis 2019

Huppes, Niek (author)After more than 85 years, the iconic Afsluitdijk is in need of a reinforcement. During the latest safety assessment of Rijkswaterstaat the dike did not meet the standards at two components; the amount of wave overtopping (>10 l/m/s) and armour stability. This research goes into detail about the overtopping on the Afsluitdijk. In the new...master thesis 2019

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

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

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

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

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
