Hard, zacht of een combinatie?: Kostenanalyse van de methoden voor kustverdediging

Al eeuwenlang wordt er in Nederland gestreden met de zee. Erosie van de kust zorgt voor een grote bedreiging van het achterland van overstromingen met vaak grote schade tot gevolg. Om de steeds waardevollere infrastructuur in het achterland te beschermen, worden er steeds verdergaande maatregelen getroffen om de kust tegen overstromingen te...

Applicability of numerical models in simulating morphological changes due to offshore breakwaters

Present strategies for coastal defence in the Dutch coast are mainly focused on conventional solutions such as revetments, dunes, dikes, groynes as well as on beach nourishment. No attention has so far been paid to the implementation of Offshore Breakwaters. An offshore breakwater is a shore parallel structure which is constructed seperately...

Modelling the impact of an offshore breakwater on the shore

This report is the result of a master thesis of the author, student at Delft University of Technology, faculty of Civil Engineering. The study was carried out at DELFT HYDRAULICS. In this report the effects of an offshore breakwater on the shore are investigated with the morphodynamic models DELFT2D-MOR and DELFT3D. These, respectively 2...

Coastal Management in the Netherlands

The coast is a very important aspect of life in the Netherlands. 60 % of the Netherlands is below the sea level, everyone lives less than 200 km from a beach, and for most people the sea is less than 50 km away. But in the Netherlands there is officially no Agency for Coastal Zone Management, neither are there laws on Coastal Zone Management. On...

Effectiveness of coastal defence measures: Design background for coastal defence and management: near field and far-field factors in overall (geometrical) and structural design

The description of the transformation of shore in larger scales, i.e. the far-field effects, is summarized in Chapter 2 while the near-field mechanisms, encompassing different overall and local failure modes, stability and performance are dealt with in Chapter 3. Both are foliowed by Chapters 4 and 5 with design computations and examples,...

General strategy on coastline protection: The Dutch case

Overview of the Netherlands policy on coastal protection and coastal defence

Living off the tides: Strategies for the integration of conservation and sustainable resource utilization along mangrove coasts

Mangroves are productive ecosystems, that sustain important fisheries, provide a variety of forest products and harbour millions of resident and migratory birds as well as endangered mammals and reptiles. Reclamation for aquaculture and agriculture is currently considered the main way to achieve development of mangrove areas. These types of...

The Dutch way to cope with storm surge disasters

Overview of the Dutch approach to sea defence

A short review of the Dutch coast

This report about the Dutch coast was written in the context of the experimental phase of the programme CORINE of the Commission of the European Communities. The programme CORINE (COoRdination of INformation on the Environment) is a programme for the gathering, coordinating and ensuring of the environment and natural sources in the Community....

Low cost shore protection

This brochure presents low cost ways for the shorel ine property owner to control or slow down shoreline erosion. lt will also be of interest to community leaders, local government officials, and contractors and engineers involved in erosion control. Prepared as a public service by the U.S. Army Corps of Engineers, the brochure is part of a...

Paalrijen als kustverdediging

Een paalrij bestaat uit naast elkaar aangebrachte vertikale palen of balken en staat als geheel loodrecht op de kust. De geometrie van paalrijen (in bovenaanzicht) komt overeen met die van stenen strandhoofden. Het primaire doel van paalrijen is het reduceren van het langstransport, waardoor een eventuele erosie wordt verminderd of een aanwas...

One aspect of the dynamics of a coast, partly protected by a row of groynes

A mathematical theory about phenomena that occur if on a coastal area groynes are constructed. The theory is a simplification: it just deals with one aspect. The starting point in the coastal equation of Pelnard-Considère and a linearisation between the transport along the groyne and the size of the 'step' in the coastline at the groyne. The...
