Towards emission-free sea dike revetments: Making sustainable design choices by employing probabilistic safety assessment and integrating the environmental cost indicator in the parametric design process of sea dike revetments

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...

Hydraulic performance of CoastaLock armour units

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...

Experimental study on wave-induced scour in front of sloping coastal structures and the influence of bed protection

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...

Shellfish as a protection of revetments: A case study in the Port of Rotterdam

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...

Rear-Slope Revetment Stability Approached by the Wave Overtopping Simulator: Experiments Regarding the Stability of Single-Layer Cube Revetment on Breakwater Crests and Rear Slopes

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...

Vergelijkend onderzoek zetstenen voor dijken: Samenvattend rapport

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...

Duurzaamheid van Elastocoast

In dit onderzoek is een voorzet gemaakt voor een sterktebeproeving van verouderd Elastocoast door middel van cilindrische proefstukken. Daarnaast is een vervolgevaluatie gemaakt van de proefvakken bij Petten en Zuidbout, alsmede een eerste evaluatie van het productievak Elastocoast bij Bath langs de Oosterschelde.

Early colonization of littoral communities on polyurethane coated substrates: A field and laboratory study

Materials used for urbanized coastal structures often create a hard substra te ready to be colonized. Elastocoast, a new coastal protection material made from stones and polyurethane, is such a material. This study examined the recovery and growth during the winter of 2007-2008 of the biological community on two dykes in the Netherlands which...
