Inbreken via internet is een fact of life geworden. Eén van de uitdagingen voor de ICT-beveiligers is dat nieuwe inbraaktechnieken zeer snel hun weg vinden naar elke internettoegangsdeur. Professionele internetcriminaliteit is geen toekomstige bedreiging; het is volop aanwezig. Inbraaksoftware wordt in eerste instantie vaak gemaakt door...

In the low-lying coastal regions coastal defence structures are usually designed with a main function to protect the hinterland from highly vulnerable to coastal flooding. Sea dikes are usually the most common and important elements which form the coastal flood defence system. Sea dikes are designed at a pre-defined circumstance and requirement....

Experience has shown that the stability parameters relating to breakwater armour unit stability vary considerably for steep foreshores when compared to milder foreshore slope. Furthermore, the change from the deep water spectra (Tm0) to the shallow water wave spectra (Tm-1.0) does not fully explain the difference. Leading on from recent...

Report on laboratory tests on a crest drainage dike; investigation if a channel in the crest of the dike is able to decrease the amount of overtopping over the dike. Chapter 2 provides details about findings from previous studies and the relevance of those findings to this research project. Available literature on wave run-up and wave...

The present report deals with the application of a provisional Smart Grass Reinforcement (SGR) system in 2006 for full scale testing of increased overtopping at the Groningen sea dyke test section near Delfzijl, as envisaged in 2007. The SGR has been placed at two strips of 4 m wide: one primary strip at the basic test site and one at a...

In the present report field erosion tests of the inner slope of a sea dyke in the province of Groningen (near Delfzijl) are described for the situation of severe wave overtopping. Three types of tests have been performed: tests at the present grass cover, tests at a reinforced grass cover and tests at a section of bare clay. At the reinforced...

The wave overtopping simulator is a device which is able to simulate overtopping waves at the crest of a dike and at the inner slope. The device has been used in the ComCoast project to test a traditional dike section with grass and the SGR, the Smart Grass Reinforcement, placed in May 2006. This report describes in the first part (Chapters 1-6)...

The Rhine River in the Netherlands, the Yellow River in China and the Mississippi River in the U.S. are three great rivers in the world. Each of them is performing a significant role in the country. The delta area for each river, in particular, is served as the centre in importance and commonly the most developed region in the whole river basin....

An important element in the ComCoast concept is the overtopable sea defence, often a dike.The landward (inner) slope of the dike is adjusted in such a way that it can withstand higher overtopping rates. One of the concepts to improve the resistance is the "Sandy Dike", a cover of the inner slope with layer sand. The sand will be washed away...

Climate change will cause increasing physical loads on the flood defence of the Province of Groningen along the North Sea over the next decades. This is caused by a sea level rise between 15 and 35 centimetres whilst the ground level is lowering between 38 and 48 centimetres until the year 2050. This results in salt-water intrusion into the land...

De Zeeuwse kust staat onder druk. Naar verwachting zal de zeespiegel deze eeuw ongeveer 60 centimeter stijgen door klimaatverandering. Niet alleen de zee, maar ook de rivieren zorgen naar alle waarschijnlijkheid voor een stijging. De deltawateren zijn nu weliswaar afgesloten van Rijn, Maas en Schelde, maar in de toekomst wordt wellicht de...

The Dutch coast carries a variety of values. With its diversity in dune areas, its shallows and the delta areas, the coastal area of the Netherlands has a high ecological value, forming a unique biotope for a great variety of plant and animal species, and providing an important foraging area for migrating birds. The economic importance of the...

The aim of this evaluation is to gain insight in the social, economic en ecological impacts of an overtopping resistant dike compared to a traditional dike in combination with different forms of land use in the hinterland. At the same time this pilot study should provide support the decision makers of the province of Groningen to find solutions...

Dit rapport beschrijft een veiligheidsanalyse van het ComCoast-concept voor de BreeBaart-polder te Groningen. Het ComCoast-concept gaat uit van een brede waterkering, waarbij de primaire dijk overslagbestendig is en de achterliggende polder wordt benut voor het opvangen van het overslaande water.

The main focus of this report is to describe the economic appraisal techniques applied to the RCFMS. The majority of the discussions on policies and procedures are specific to England. An overview of the differing funding processes and procedures in the rest of the UK (Wales, Scotland and Northern Ireland) is provided in Appendix A. In addition,...

The problem formulation of this quick scan is twofold: Is it possible to fully incorporate the citizens' perspective (for example in the form of experiential value) in a socio-economic evaluation? And does it serve a useful purpose? In this context, the concept of the citizen denotes the user of the (project) site, including neighbouring...

A desk study has been carried out in order to develop a conceptual model for the erosion of inner dike slopes with reinforced grass cover. Based on the results the following can be concluded: The presence of a geosynthetic in a grass slope can be taken into account in the EPM method by increasing the critical flow velocity. In particular, a...
