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...

This study explores the influence of the wave characteristics on the attenuation process of waves through coastal mangroves, which are threatened by the coastal mangrove squeeze phenomenon. Coastal mangrove squeeze is the phenomenon where coastal regions, even when sediment availability is sufficient, are eroding due to a lack of accommodation...

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...

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...

Torsional forced-oscillation experiments on a suite of synthetic MgO polycrystals, of high-purity and average grain sizes of 1–100 µm, reveal strongly viscoelastic behavior at temperatures of 800–1300°C and periods between 1 and 1000 s. The measured shear modulus and associated strain energy dissipation both display monotonic variations with...

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...

Coastal populations are particularly vulnerable to the impacts of extreme events such as storms and hurricanes, and these pressures may be exacerbated through the influence of climate change and sea level rise. Coastal ecosystems such as mangrove forests are increasingly being promoted and used as a tool in coastal defence strategies. There...

A study of the effectiveness of mangroves in attenuating cyclone- induced waves was done using the SWAN 40.81 numerical model. Hydraulic parameters during extreme events and local mangrove vegetation parameters were estimated for the Kanika Sands mangrove island near the upcoming Dhamra Port in Orissa, India. Simplified generic analyses were...

The goal of the uncertainty analyses within the SBW Wadden Sea project is to find out which accuracy in HBC can be achieved, given the current state of scientific knowledge and technical instruments. Furthermore, we wish to quantify the contribution of the SWAN model and other components to the overall uncertainty in HBC. In order to answer...

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...

Mol, A.C.S. (author)
Measurements have been carried out at the Paulinaschor, a salt marsh in the Westerschelde, to obtain information of the effect of vegetation on wave attenuation. The data have been analyzed. It appears that wave height is strongly reduced by the vegetation, especially for low water depths. Further analysis of the data has been done, to achieve...

Low, E. (author)
The main topic of this dissertation is concerned with potential sea wave attenuation by salt marsh vegetation. The overall structure of the dissertation is divided into a literature review and an experimental paper, which is further divided into an in-situ and ex-situ study. Salt marshes have some protected status within the EU and much study is...

Pressure waves, that are generated when a high speed train enters a tiinnel, can cause annoyance to train passengers (rapid pressure fluctuations acting on the train) and for people living near the tunnel (micro-pressure wave). To improve train passenger comfort the effect of various pressure relieving measures (i.e. shafts and porous walls)...

A literature survey has been conducted on wave attenuation by vegetation with emphasis on reed which has revealed that the influence of various parameters such as the number of reed stalks per unit horizontal area and the dynamic behaviour of the stalks is not known. The two analytical solutions found in this survey are based on linearized...

This study deals with the breaking of waves on coastal reefs, with special emphasis on energy dissipation (wave height attenuation), wave spectrum modification and the characteristics of wave set-up. It has an engineering perspective; its main objective is to provide the practicing engineer with much needed information on the design conditions...

A semi-empirical study l~as made of the attenuation of water waves in a rectangular channel, the side walls of which had been provided with regularly spaced roughness strips. Such strips were found to be highly effective wave dampers. A dimensionless resistance coefficient could be deduced from the attenuation data; this coefficient was mainly a...
