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 the effect of twin storms on dune erosion: Applying XBeach to model the dune erosion for single and twin storms constructed using simulated weather data

When two storms quickly succeed one another, it can be called a twin storm. Storm conditions at the coast can lead to higher water levels and waves that can give rise to dune erosion. Therefore, after a storm the dunes are smaller than before the storm. Dune accretion is a much slower process than dune erosion; it can take weeks to months of...

Predicting erosion of vegetated dunes during hurricanes: Assessing the representation of vegetation effects in XBeach

Coastal dunes serve as the primary defence mechanism against coastal storms for many coastal communities around the world. Vegetation plays a role in increasing dune resiliency as it enables dune growth, however not enough is known about its effects during storms. Research has shown that the current climate crisis will increase the intensity of...

Influence of Sandy Foreshores on Overtopping in Non-Tidal Low-Energy Shallow Lake Environments

Sea level rise will increase the risk of flooding in coastal areas. This poses a risk to the coastal protection as well as rivers and lakes close to the coast. Solutions are needed to cope with this threat. The past decade, nature based solutions have gained significant interest. One of these solutions could be sandy foreshores. Due to the use...

The potential of dune vegetation during storm conditions: Assessing the applicability of XBeach in dune rehabilitation projects

Coastal protection is required to keep coastal areas protected during storm conditions. Coastal dunes are a natural defense against flooding and erosion from the sea against storms. Many insights have been obtained regarding the positive effects of coastal dune vegetation on dune formation and growth in the past. Several recent studies have...

Impact of Free Long Waves on Dune Erosion Predictions in Numerical Modelling

This report presents the methodology and findings of a study on the impacts of free long waves on dune erosion predictions in XBeach. In this paper a distinction is made between two types of infragravity waves: bound infragravity waves and free infragravity waves. Bound infragravity waves are generated by short-wave group forcings and are bound...

Present and future coastal safety assessment of 'De Slufter' anticipating sea level rise and coastal management changes: Modelling the effects of a natural coastal management strategy on the morphodynamic development and coastal safety of De Slufter on Texel with XBeach Surfbeat

'De Slufter' is a nature conservation area located in the Northwest of the Dutch Wadden island Texel which is inundated with seawater during storm events. The landward side of De Slufter is a sand dike which is part of the primary coastal defence ring of the island. HHNK, which is responsible for the coastal safety of Texel, currently relocates...

Modelling the 1775 storm surge deposits at the Heemskerk dunes

After a storm surge in November 2007, older storm surge deposits were discovered in the eroded dunes near Heemskerk, the Netherlands. These deposits undulate in height with a maximum elevation of over 6 m above mean sea level. Luminescence dating suggests that the layers were deposited by either the 1775 or the 1776 storm surge. The aim of this...
