Building With Nature: A System Analysis of Dynamic Double Dike Systems

Jansen, Martijn (author)

Sea level rise and land subsidence increasingly put more pressure on Dutch flood protections. Additional to regular dike reinforcements, new, more nature-based, solutions are considered, such as a double dike system (DDS). Such system, consisting of two parallel dikes in combination with an interdike area in the form of a salt marsh, offers the...

Long-term morphological modelling of tidal inlet systems: Implementing salt marshes in ASMITA

Bonenkamp, Marloes (author)

A rise in the global mean temperature induced by climate change is expected to have a large impact on ecosystems in all regions of the world. One of the threats is accelerated sea level rise (SLR). This may induce the loss of intertidal areas in tidal inlet systems. The long-term morphological response of tidal inlet systems can be modelled...

Modeling Decadal Salt Marsh Development: Variability of the Salt Marsh Edge Under Influence of Waves and Sediment Availability

Willemsen, P. W.J.M. (author), Smits, B. P. (author), Borsje, B. W. (author), Herman, P.M.J. (author), Dijkstra, J. T. (author), Bouma, T. J. (author), Hulscher, S. J.M.H. (author)

Salt marshes can contribute to coastal protection, but the magnitude of the protection depends on the width of the marsh. The cross-shore width of the marsh is to a large extent determined by the delicate balance between seaward expansion and landward retreat. The influence of the magnitude of daily occurring mild weather conditions and...

Salt marshes: habitat suitability and flood hazard reduction effectiveness

Mendoza Viteri, Marco (author)

In recent years, nature-based solutions have gained recognition for their capacity to reduce flood hazard on coastal communities. These coastal threats range from waves and tides, to future storm variability and predicted sea level rise. Vegetated foreshores are one of the measures that fall under this palette of solutions, and are the focus of...

A Cross-System Comparison of Dark Carbon Fixation in Coastal Sediments

Vasquez Cardenas, D. (author), Meysman, F.J.R. (author), Boschker, H.T.S. (author)

Dark carbon fixation (DCF) by chemoautotrophic microorganisms can sustain food webs in the seafloor by local production of organic matter independent of photosynthesis. The process has received considerable attention in deep sea systems, such as hydrothermal vents, but the regulation, depth distribution, and global importance of coastal...

On the Impact of Salt Marsh Pioneer Species-Assemblages on the Emergence of Intertidal Channel Networks

Bij de Vaate, I. (author), Brückner, M. Z.M. (author), Kleinhans, M. G. (author), Schwarz, C. (author)

Tidal marshes play an important role in climate change mitigation through natural coastal protection. The effectiveness of the natural coastal defense by tidal marshes is closely related to their channel network which is in turn greatly influenced by their vegetation cover and shape. Previous research suggests a dual effect of vegetation on...

Burrowing fauna mediate alternative stable states in the redox cycling of salt marsh sediments

van de Velde, Sebastiaan J. (author), Hidalgo-Martinez, Silvia (author), Callebaut, Ine (author), Antler, Gilad (author), James, Rebecca K. (author), Leermakers, Martine (author), Meysman, F.J.R. (author)

The East Anglian salt marsh system (UK) has recently generated intriguing data with respect to sediment biogeochemistry. Neighbouring ponds in these salt marshes show two distinct regimes of redox cycling: the sediments are either iron-rich and bioturbated, or they are sulphide-rich and unbioturbated. No conclusive explanation has yet been...

How natural processes contribute to flood protection: A sustainable adaptation scheme for a wide green dike

Marijnissen, Richard (author), Esselink, Peter (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

Effective adaptation to sea-level rise is critical for future flood protection. Nature-based solutions including salt marshes have been proposed to naturally enhance coastal infrastructure. A gently sloping grass-covered dike (i.e. Wide Green Dike) can be strengthened with clay accumulating locally in the salt marsh. This study explores the...

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...

The sensitivity of a dike-marsh system to sea-level rise-a model-based exploration

Marijnissen, Richard (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)

Integrating natural components in flood defence infrastructure can add resilience to sea-level rise. Natural foreshores can keep pace with sea-level rise by accumulating sediment and attenuate waves before reaching the adjacent flood defences. In this study we address how natural foreshores affect the future need for dike heightening. A...

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...

Beneficial use of dredged sediment to enhance salt marsh development by applying a ‘Mud Motor’

Baptist, Martin J. (author), Gerkema, T. (author), van Prooijen, Bram (author), van Maren, D.S. (author), Colosimo, I. (author), Elschot, K. (author), de Groot, A. V. (author), Cleveringa, J. (author), van Eekelen, E. M.M. (author)

We test an innovative approach to beneficially re-use dredged sediment to enhance salt marsh development. A Mud Motor is a dredged sediment disposal in the form of a semi-continuous source of mud in a shallow tidal channel allowing natural processes to disperse the sediment to nearby mudflats and salt marshes. We describe the various steps in...

Quantifying Bed Level Change at the Transition of Tidal Flat and Salt Marsh: Can We Understand the Lateral Location of the Marsh Edge?

Willemsen, P. W.J.M. (author), Borsje, B. W. (author), Hulscher, S. J.M.H. (author), Van der Wal, D. (author), Zhu, Z. (author), Oteman, B. (author), Evans, B. (author), Möller, I. (author), Bouma, T.J. (author)

Bed level dynamics at the interface of the salt marsh and tidal flat have been highlighted as a key factor connecting the long-term biogeomorphological development of the marsh to large-scale physical forcing. Hence, we aim to obtain insight into the factors confining the location of the marsh edge (i.e., boundary between tidal flat and salt...

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...
