Dynamic Dunes 2015, daring solutions for Natura 200 challenges

Proceedings of an international conference on rejuvenation of dynamic dunes and restoration of the dune habitats. The congress was held in the framework of EU Life-projects Dutch Dune Revival, in Rockanje, Netherlands.

Coastal Erosion and Solutions: A primer

This primer describes some of the causes of coastal erosion and tries to put into perspective their scale and consequences. There are no uniform causes, just as there are no uniform solutions. Erosion tends to be site-specific. Yet, with careful observation and measurement, a particular problem can be placed in context and draw from the...

Influence of collapsed revetments on dune erosion: Large-scale model tests

Dune erosion - product 3: Probabilistic dune erosion prediction method

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...

The development and hydraulic roughness of subaqueous dunes

Research on bedforms, especially river dunes with focus on the Dutch river Waal, and the effect of these bedforms on the hydraulic roughness of the river. Morphological descriptions, prototype measurements and flume experiments. PhD thesis Utrecht University.

A Vertical Sorting Model for Rivers with Non-uniform Sediment and Dunes

Vertical sorting fluxes and the resulting organisation of grain size fractions over bed elevations, i.e. the vertical sorting profile, influence bedform dimensions and the bed surface composition. As a result, they will affect the bed roughness, the rate and composition of the sediment transport, the large-scale river morphology, and water...

Hydraulic and coastal structures in international perspective

The objective of this paper is to bring some international perspectives on the policy, design, construction, and monitoring aspects of Hydraulic and Coastal Structures in general, and whenever possible, to present some comparison (or reasons for differences) between the experiences of various countries and/or geographical regions. This chapter...

Coastal Dune Management: A Manual of Coastal Dune Management and Rehabilitation Techniques

This manual represents a renewed effort by the Department of Land and Water Conservation to present an up-to-date document on how we can best manage our dune landscapes. It builds on the many efforts of past dune managers and offers the community practical advice on the ways we can care for the plants, animals and topographic features within the...

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...
