Integrating mangrove growth and failure in coastal flood protection designs

Gijón Mancheño, A. (author), Vuik, V. (author), van Wesenbeeck, B (author), Jonkman, Sebastiaan N. (author), van Hespen, R. (author), Moll, J.R. (author), Kazi, S. (author), Urrutia, I. (author), van Ledden, M. (author)

Mangrove forests reduce wave attack along tropical and sub-tropical coastlines, decreasing the wave loads acting on coastal protection structures. Mangrove belts seaward of embankments can therefore lower their required height and decrease their slope protection thickness. Wave reduction by mangroves depends on tree frontal surface area and...

Longshore sediment transport by large-scale lake circulations at low-energy, non-tidal beaches: A field and model study

Ton, A.M. (author), Vuik, V. (author), Aarninkhof, S.G.J. (author)

Low-energy, non-tidal lake beaches are known to be subject to longshore morphodynamics, but little is known about how they are driven by wind and wave-driven currents. Lake Markermeer is a shallow (∼4 m deep), wind-dominated lake, of approximately 700 km². A gradient in wind-induced water level set-up at the leeward shore induces a...

The influence of infragravity waves on the safety of coastal defences: a case study of the Dutch Wadden Sea

Lashley, Christopher H. (author), Jonkman, Sebastiaan N. (author), van der Meer, J.W. (author), Bricker, J.D. (author), Vuik, V. (author)

Many coastlines around the world are protected by dikes with shallow foreshores (e.g. salt marshes and mudflats) that attenuate storm waves and are expected to reduce the likelihood and volume of waves overtopping the dikes behind them. However, most of the studies to date that assessed their effectiveness have excluded the influence of...

Morphological wave attenuation of the nature-based flood defense: A case study from Chongming Dongtan Shoal, China

Mi, Jie (author), Zhang, Min (author), Zhu, Zhenchang (author), Vuik, V. (author), Wen, Jiahong (author), Gao, Hongkai (author), Bouma, Tjeerd J. (author)

The risk of coastal storm flooding is deteriorating under global warming, especially for the heavily urbanized deltaic cities, like Shanghai. The Nature-Based Flood Defense (NBFD), as an eco-friendly design alternative for hard infrastructure against coastal flooding, is gaining attention. Nevertheless, the vulnerability of saltmarsh due to...

Tidal flats provide valuable ecosystem services such as flood protection and carbon sequestration. Erosion and accretion processes govern the ecogeomorphic evolution of intertidal ecosystems (marshes and bare flats) and, hence, substantially affect their valuable ecosystem services. To understand the intertidal ecosystem development, high...

Sandy beaches in low-energy, non-tidal environments: Linking morphological development to hydrodynamic forcing

Ton, A.M. (author), Vuik, V. (author), Aarninkhof, S.G.J. (author)

The morphodynamic behaviour of low-energy beaches is poorly understood, compared to that of exposed coasts. This study analyses the morphological development of sandy, low-energy beaches and the steering hydrodynamic processes. Four densely-monitored study sites in the non-tidal lake Markermeer in the Netherlands offered a unique opportunity...

Field-based decadal wave attenuating capacity of combined tidal flats and salt marshes

Willemsen, Pim W.J.M. (author), Borsje, Bas W. (author), Vuik, V. (author), Bouma, Tjeerd J. (author), Hulscher, Suzanne J.M.H. (author)

Foreshores consisting of both bare tidal flats and vegetated salt marshes are found worldwide and they are well studied for their wave attenuating capacity. However, most studies only focus on the small scale: just some isolated locations in space and only up to several years in time. In order to stimulate the implementation of foreshores...

Historic storms and the hidden value of coastal wetlands for nature-based flood defence

Zhu, Zhenchang (author), Vuik, V. (author), Visser, P.J. (author), Soens, Tim (author), van Wesenbeeck, B (author), van de Koppel, Johan (author), Jonkman, Sebastiaan N. (author), Temmerman, Stijn (author), Bouma, T.J. (author)

Global change amplifies coastal flood risks and motivates a paradigm shift towards nature-based coastal defence, where engineered structures are supplemented with coastal wetlands such as saltmarshes. Although experiments and models indicate that such natural defences can attenuate storm waves, there is still limited field evidence on how...

Salt marshes for flood risk reduction: Quantifying long-term effectiveness and life-cycle costs

Vuik, V. (author), Borsje, Bas W. (author), Willemsen, Pim W.J.M. (author), Jonkman, Sebastiaan N. (author)

Flood risks are increasing worldwide due to climate change and ongoing economic and demographic development in coastal areas. Salt marshes can function as vegetated foreshores that reduce wave loads on coastal structures such as dikes and dams, thereby mitigating current and future flood risk. This paper aims to quantify long-term (100 years)...

Building safety with nature: Salt marshes for flood risk reduction

Vuik, V. (author)

Flood risk reduction in coastal areas is traditionally approached from a conventional engineering perspective, where dikes and dams are built to withstand the forces of tides, surges and waves. Recently, a nature-based approach to flood risk reduction is increasingly promoted, in which the benefits of coastal ecosystems for reducing the impact...

Assessing safety of nature-based flood defenses: Dealing with extremes and uncertainties

Vuik, V. (author), van Vuren, S. (author), Borsje, Bas W. (author), van Wesenbeeck, B (author), Jonkman, Sebastiaan N. (author)

Vegetated foreshores adjacent to engineered structures (so-called hybrid flood defenses), are considered to have high potential in reducing flood risk, even in the face of sea level rise and increasing storminess. However, foreshores such as salt marshes and mangrove forests are generally characterized by relatively strong temporal and...

Stem breakage of salt marsh vegetation under wave forcing: A field and model study

Vuik, V. (author), Suh Heo, H.Y. (author), Zhu, Zhenchang (author), Borsje, Bas W. (author), Jonkman, Sebastiaan N. (author)

One of the services provided by coastal ecosystems is wave attenuation by vegetation, and subsequent reduction of wave loads on flood defense structures. Therefore, stability of vegetation under wave forcing is an important factor to consider. This paper presents a model which determines the wave load that plant stems can withstand before...

Wave attenuation by salt marsh vegetation

Vuik, V. (author), Jonkman, Sebastiaan N. (author)

Salt marshes are a characteristic feature of estuaries and coastal seas. They are found in the upper coastal intertidal zones between land and water, which are regularly flooded by tides and surges. They are covered with salt-tolerant vegetation types, such as herbs and grasses. Sheltering from continuous intense hydrodynamic forcing by waves...
