Experimental investigation of wave attenuation by mangrove forests with submerged canopies

Mangroves can function as a ‘bio-shield’ to protect coastal communities from harsh environments because of their strong ability to attenuate wave energy. However, as mangroves are usually oversimplified as rigid cylinders in antecedent studies, the effects of complex mangrove morphology on wave attenuation have not been well researched....

Numerical and small-scale physical modelling of wave transmission by wooden fences

Mangrove forests, that often act as natural coastal defences, enormously suffered due to ongoing climate change and human disturbances. Thus, it is necessary to have a countermeasure to mitigate the loss of mangroves. Wooden fences are becoming a viable nature-based solution to protect vulnerable replanted mangrove forests. However, the wooden...

Efficient and accurate PLIC-VOF techniques for numerical simulations of free surface water waves

In this paper the attention is focused on the effect of various VOF methods on efficient and accurate simulation of free surface water waves. For this purpose, we will compare several VOF methods in numerical simulations of propagating waves where strong nonlinear behavior is dominant in the flow. Comparisons and discussions will be provided to...

Wave Generation, Propagation and Absorption in CFD Simulations of Free Surface Flows

The PhD study focused on two topics. The first topic was energy dissipation in wave propagation. The wave dissipation can be caused by physical and/or numerical phenomena, such as the free surface treatment, physical viscosity and artificial viscosity due to discretization of the momentum equations. Among these the free surface treatment is an...

Modeling of wave attenuation by vegetation with XBeach

Over the past decades the effect of vegetation (e.g. kelp, mangroves, sea grass) on nearshore coastal processes has received more and more attention. In recent years several numerical wave models have been extended to include this effect. In the current study, the numerical storm impact model XBeach was extended with formulations found in...

Experimenteel onderzoek naar het effect van Ground Consolidators op golven (Anome)

Onderzoek uitgevoerd in het Laboratorium voor Vloeistofmechanica van de TU Delft van 9 november tot 18 december 2009. Dit rapport bevat de meetresultaten en conclusies van proeven met GC’s (Ground Consolidators) die zijn uitgevoerd in november en december 2009 in het Laboratorium voor Vloeistofmechanica van de TU Delft. Het doel van de proeven...

Wave attenuation by artificial reefs

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...

Liquefaction and erosion of mud due to waves and current: Experiments on Westwald Clay

A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...
