Dune erosion - Product 2: Large-scale model tests and dune erosion prediction method

The dune erosion prediction method presently used to assess the safety level of dunes along the Dutch coast was developed for situations with wave periods up to Tp = 12 seconds, while situations can be expected with wave periods larger than Tp = 12 seconds. Preliminary analyses of the potential influence of longer wave periods on dune erosion...

Dune erosion - Product 1: Deterministic dune erosion prediction methods

The dune erosion prediction method presently used to assess the safety level of dunes along the Dutch coast was developed for situations with wave periods up to Tp = 12 seconds, while situations can be expected with wave periods larger than Tp = 12 seconds. Preliminary analyses of the potential influence of longer wave periods on dune erosion...

Breaching of dunes - Preliminary quantification of related mechanism and assessment of the probability of occurrence

In order to yield an expression for the probability of breaching, in this desk study the mechanism that play a role in the initiation of breaching of dunes are described and preliminary quantified. In addition a pragmatic description for the assessment of the combined probability of breaching is elaborated. From this it was concluded that...

Coastal Protection and Dune Management in The Netherlands

Because dunes protect a large part of The Netherlands against coastal flooding and inundation, it is vital to guarantee the strength of these natural sea defenses. Besides sea defense, dunes have other functions. Sandy shorelines and dunes are frequently eroded. A legal framework has been developed that guarantees the required safety-level of...

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 7: Duinen als waterkering

De veiligheidsbeschouwing van de duinenkust is gebaseerd op de beoordelingsmethodiek die ontwikkeld is door de TAW en vastgelegd is in de Leidraad voor de beoordeling van de veiligheid van duinen als waterkering. Volgens deze methode is een duinwaterker ing veilig als de kans op onderlopen van het achterliggende polderland t g v een...

Sand stabilization and dune building

The growth of dune vegetation can be stimulated by the application of suitable fertilizers. Newly planted seedlings and sparse vegetation on the sea dunes can be very much improved by this means, provided the quantity of windblown sand is not excessive. Otherwise sand fences have to be constructed for stabilization purposes. Marram grass and...
