Dune Erosion on the Falsterbo Peninsula: Assessing the Dune System for Coastal Safety in Regions with Complex Interactions Between Waves and Water levels

The Falsterbo Peninsula is a low-lying area that provides a home to 7,000 residents, as well as various bird and vegetation species. To protect this densely populated area, the municipality was granted a permit to build flood protections. As part of the strategy, the dune system in the study area will be used as natural barriers against storm...

Modelling stability of Avicennia marina mangroves under wave and wind loads: Effect of soil and root system on tree resistance

Mangroves can provide coastal protection by attenuating waves, currents, and trapping sediment (Menéndez et al., 2020; Bao, 2011). The effect of mangroves on the hydrodynamics depends on their size, location, density, distribution and morphology of the vegetation (Mendez and Losada, 2004). Mangrove loss during storm events will therefore impact...

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...

Colored Water: Designing a resilient landscape framework that facilitates water safety and batik development in Pekalongan city

As one of the most important ecosystems on the planet, the coastal zone accommodates a denser population than the hinterland and faces faster urbanization and higher population growth. Meanwhile, the coastal zone is exposed to several climate change disasters in the context of a sensitive environment dominated by water. It is considered with...

Towards a nature-based solution for the Brouwersdam beach in the Netherlands: Following the Building with Nature approach to counteract long-term erosion of a recreational beach as a consequence of large-scale morphological changes in a closed-off outer delta

Since the Brouwersdam was built as part of the Delta plan, the Grevelingen outer delta undergoes large-scale morphological changes. These changes led to the formation of a shoal adjacent to the dam, which is referred to as the Brouwersdam beach. The beach has been eroding and shifting towards the northeast ever since. The beach has no safety...

Bridging the dike: an architectural intervention to unlock environmental engineering as a common ground

The Dutch sea water level raised with 24cm over the last 128 years. From a linear increase, we can see an increasing trend since the 1990s. According to recent scientific research, the sea level in the Netherlands will rise 1 to 2 meters by 2100 with a maximum global warming of 2 degrees Celsius. With a temperature rise of 4 degrees, the North...

Coastal protection in the Mekong Delta: Investigation of shore nourishment and mangroves as Building with Nature solutions

To help to provide a desperately needed coastal protection strategy for the Mekong Delta in Vietnam this research looks into the possibilities for natural and sustainable coastal defence systems, including mangroves and active sediment management, such as a nourishment. The coastline of the Mekong Delta suffers from severe erosion and mangrove...

Coastal Adaptation to Climate Change: A case study in Durban, South Africa

Research done by the IPCC working groups and other organizations has sparked global concern over the possible impacts of climate change and corresponding sea level rise upon coastal communities. In reaction global studies were done (Nicholls et al., 2008, Hanson et al., 2011) to assess the vulnerability of coastal regions. However, most of these...

Feasibility study on the use of a floating breakwater to protect a new artificial beach in Balchik, Bulgaria

The coast of Bulgaria is subject to erosion. Because of this fact, around the town of Balchik, which is situated on the Black Sea coast, almost no sandy beaches are present. Last years there have been vast tourist developments in and around Balchik. Because of these developments, the province demands solutions to adapt coastal protection...

A Numerical Study on Design of Normal and T-Head Coastal Groins

Groins are old and intuitive means of reducing erosion and are found along the coast worldwide, although according to CEM (Coastal Engineering Manual 2003), “they are probably the most misused and improperly designed of all coastal structures”. The original purpose of groins was to reduce local erosion, that is, to hold the width of beach in...

Eigenschappen van gabionboxen onder golfaanval

Dit afstudeerverslag handelt met name over de golftransmissiecoefficient van gabionboxen belast door golven. Het onderzoek is uitgevoerd in het kader van een afstudeerproject aan de Technische Universiteit Delft, in samenwerking met baggermaatschappij Boskalis. Gabions worden op dit moment vooral toegepast als bodembescherming tegen de...

The impact of gas extraction and sea level rise on the morphology of the Wadden Sea: Extension and application of the model ASMITA

It is the policy of the Dutch government to aim at the extraction of gas from the smaller gas fields in The Netherlands to spare the large Slochteren field in Groningen. The gas reservoirs below the Wadden Sea are counted among the smaller fields. Their capacity is estimated to 200 thousand million cubic metres, and their economic value is equal...

Hard, zacht of een combinatie?: Kostenanalyse van de methoden voor kustverdediging

Al eeuwenlang wordt er in Nederland gestreden met de zee. Erosie van de kust zorgt voor een grote bedreiging van het achterland van overstromingen met vaak grote schade tot gevolg. Om de steeds waardevollere infrastructuur in het achterland te beschermen, worden er steeds verdergaande maatregelen getroffen om de kust tegen overstromingen te...

Modelling the impact of an offshore breakwater on the shore

This report is the result of a master thesis of the author, student at Delft University of Technology, faculty of Civil Engineering. The study was carried out at DELFT HYDRAULICS. In this report the effects of an offshore breakwater on the shore are investigated with the morphodynamic models DELFT2D-MOR and DELFT3D. These, respectively 2...

Paalrijen als kustverdediging

Een paalrij bestaat uit naast elkaar aangebrachte vertikale palen of balken en staat als geheel loodrecht op de kust. De geometrie van paalrijen (in bovenaanzicht) komt overeen met die van stenen strandhoofden. Het primaire doel van paalrijen is het reduceren van het langstransport, waardoor een eventuele erosie wordt verminderd of een aanwas...
