Integrating coral habitat potential and coastal protection services in design of artificial reefs: A case study in Addu City, Maldives

This research focuses on the implementation of the Building with Nature (BwN) approach in the design of artificial coral reefs. The goal is to explore environmental preferences and design tools for coral development, considering both coral habitat potential and coastal protection services. The research also aims to optimize artificial reef...

Numerical modeling of wave transmission over a living breakwater

Living Breakwaters have evolved from traditional breakwaters to create multi-purpose structures that provide environmental and social benefits. These breakwaters promote a healthy habitat for flora and fauna, while achieving the same structural capabilities as conventional structures. Reefy has developed a modular living breakwater that can...

Physical Modelling of 3D-Printed Artificial Reefs with Complex Shapes in the Wave Flume

Coral reefs are considered to be a crucial ecosystem and form of natural coastal protection. They owe their effectiveness to their high structural complexity. This complexity, which positively influences aspects like species richness, coral recovery, live coral cover, and coastal protection, is often quantified using parameters such as porosity...

Wave transmission at submerged coastal structures and artificial reefs

Wave transmission at low-crested coastal structures has been studied, based on physical model tests with trapezoidal impermeable, permeable and perforated structures. The differences between wave transmission at impermeable and permeable structures are relatively limited. For a perforated hollow structure with an impermeable vertical screen...

Wave Transmission over Artificial Reefs: A Physical Model Study

In this research, the influence of the permeability and the porosity of artificial reefs on wave transmission and the sheltered habitat of marine life is investigated. A physical model is used to find the answer to this question. <br/>The main finding of this research is that a hollow, perforated structure can act both as an artificial reef that...

Experimental wave flume study: the stability of an artificial reef

The objective of this master thesis is to investigate experimentally how non-breaking wave loading affects the stability of the MOSES artificial reefs, an artificial reef by the company ReefSystems. Small scale wave flume tests with a length scale factor of 20 were conducted in the Scheldt flume at Deltares in Delft to determine the stability of...

Hydrodynamic and ecological performance of a new modular unit for living breakwaters: Wave flume experiments and results

Living breakwaters are designed to protect the coast against flooding and erosion, whilst at the same time they enhance the local ecological system by incorporating natural reef components. This study investigates the design of a modular artificial reef developed by the company called Reefy. Reefy breakwaters will consist of interlocking blocks...

Physical Model Study of Living Breakwaters: Stability and Ecological Analysis of Green-Grey Hybrid Structure Concept for Climate Change Adaptation

A vast majority (84%) of all countries in the world have coastlines and 80-100% of their population resides within 100 km of the shoreline. Studies show a major growth in population in low-elevation coastal zones and a scenario of rising sea level may force millions of people to relocate. To deal with the increased frequency of extreme events...

The exploration of solution strategies for the mitigation of coastal erosion by applying the BwN design process: A case study at Long Bay, Jamaica

Coastline regression is a significant threat to many coastal zones. Being able to mitigate the erosion while simultaneously improving nature development is something that is increasingly strived for in coastal projects. This report utilizes the building with nature philosophy to explore integrated solutions for a coastal erosion problem in...

Design method for multi-functional artificial reefs in a coastal environment

Natural reefs are important habitats for a wide range of species. Furthermore, they attenuate waves and thereby protect the leeside, functioning as coastal protection. Many reefs are however eroding or degraded, leading to a loss of these ecosystem services. Artificial reefs can reverse this negative trend. The artificial reefs in this context...

Process-based modelling of morphological response to submerged breakwaters

Submerged breakwaters (SBWs) are becoming increasingly popular as alternative coastal defence system due to the lack of impact on beach amenity and aesthetics compared to common emerged beach protection measures. However, the recent significant amount of failing SBWs resulting in additional shoreline erosion reported in [Ranasinghe and Turner...

Experimenteel onderzoek naar het effect van Ground Consolidators op golven (Anome)

Onderzoek uitgevoerd in het Laboratorium voor Vloeistofmechanica van de TU Delft van 9 november tot 18 december 2009. Dit rapport bevat de meetresultaten en conclusies van proeven met GC’s (Ground Consolidators) die zijn uitgevoerd in november en december 2009 in het Laboratorium voor Vloeistofmechanica van de TU Delft. Het doel van de proeven...

Wave attenuation by artificial reefs

This paper intends to demonstrate the applications of artificial reefs to a broader readership concentrating on examples in coastal protection. In Germany, artificial reefs are not widely used as a coastal protection measure probably due to limited knowledge of the potential of this kind of structures. Reefs are not intended to ensure total...

Scrap tire shore protection structures

Design manual for shore protection structures using old rubber tyres. With the use of old car tires one may construct floating breakwaters and reef breakwaters
