A design of the Delta21 sea defence using the adaptive pathway approach

Besides global warming, climate change is expected to result in (among others) an increased number of extreme precipitation events and a rising sea level. In the future, this can be the cause for an increased number of high river discharge events in combination with high water levels on the North Sea, which goes hand in hand with an increased...

Future and current sea dike reliability analysis under severe storms in Shanghai Pudong New District

Shanghai sea dikes are built to protect shorelines, factories, inland buildings and other vulnerable coastal areas against wave action and storm surge. For this reason, there is an urgent need to check whether sea dike in Shanghai can function well. The intuitive influences are sea level rise, severe storm surge, and land subsidence, which...

Reliability analysis of sea-dikes in Shanghai city, China

This research focuses on the estimation the failure probability of Shanghai sea-dikes system, taking into account several failure mechanisms. This method follows fully probabilistic approach, in which all relevant parameters for the resistances and the hydraulic loads vary according to specific distributions.

A cost optimal design of a sea dike: Using probabilistic methods and flexibility in the distribution of the total failure probability over the various failure mechanisms

During this research a method is developed for finding the cost optimal design of a sea dike when a probabilistic method is being applied and flexibility is allowed in the distribution of the total failure probability over the various failure mechanisms. A probabilistic model has been set up to calculate the cost optimal design for a sea dike...

Wave overtopping: Impact of water jets on grassed inner slope transitions

The safety of a large part of the Netherlands depends on sea dikes. Due to climate change, a sea level rise is predicted. Together with stronger storms and more wave attack, wave overtopping on the current dikes will increase. As a response, crest levels of the dikes need to be raised in order to meet the present regulations for wave overtopping...

Risk analysis for new sea dike design guidelines in Vietnam

Vietnam experienced sustained economic growth over the last decades, making it one of the fastest growing economies of the world. At this moment Vietnam is still fighting its way out of poverty and trying to improve living standards. With a coastline of 3,260 kilometers many activities take place in the densely populated coastal areas. The...

Zeedijken in een breder perspectief: Onderzoek in het kader van het project Blauwe Delta

De provincie Zeeland is bezig met het opstellen van de Integrale Visie Deltawateren. Dit afstudeeronderzoek 'waterkeren in de breedte' kijkt voor de primaire waterkeringen langs de Ooster- en Westerschelde in het kader van de veiligheid naar twee mogelijke oplossingsrichtingen als alternatief voor dijkverhoging. Het betreft hier enerzijds het...
