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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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....

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...

Many sea dikes along the coast of the North Sea are protected against wave loading and currents by riprap revetments that are grouted with mortar. The mortar bonds the individual stones of the top layer, thereby forming a coherent structure that is able to withstand normal forces and shear forces as well as momentums, thus leading to a planar...

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...

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...

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...

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...

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,...
