Effectiveness of Mangroves in Flood Risk Reduction

The risk of flood risk is increasing with global trends such as rising sea levels, land subsidence, increasing populations in coastal areas and economic growth. Traditional solutions to reduce flood risk are a levee or a dam; however, the research on hydraulic engineering is increasingly promoting nature-based solutions for flood protection....

Optimization of flood safety levels: Case study for unembanked areas in the Port of Rotterdam

Modelling the phreatic surface in regional flood defences

The phreatic surface is an important factor of influence on the stability and therefore the safety of regional flood defences. For stability calculations usually a schematisation of the phreatic surface is used, based on the geometry of the flood defence and the water levels. The influence of precipitation and evapotranspiration is not...

Wave-induced stem breakage in a vegetated foreshore and its implication on probability of flooding

Various flood protection measures are studied across the globe, and nature-friendly and environmentally resilient methods are gaining more attention. As part of the building with nature initiative, the project BE SAFE (Bio-Engineering for SAFEty) studies the effects of a vegetated foreshore as a flood protection measure which is found to be very...

Use of Compartment Dikes as a Flood Management Strategy in Schouwen-Duiveland

CIE4061 Multidisciplinary Project: We were tasked with determining the feasibility of dike compartments to mitigate flood risk in Schouwen-Duiveland, The Netherlands. The primary dike protecting the polder of Bruinisse is vulnerable to piping failure, leading to a high probability of flooding. In the event of a flood, the small but deep polder...

Design of a breach retardant dike

Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...

Reliability methods for finite element models

Probabilistic techniques in engineering problems are needed because they provide a deeper understanding of failure mechanisms and occurrence probabilities than deterministic techniques. In addition, they draw our attention to the consequences of failure at an early stage in the design process. However, to achieve these advantages, a well-defined...

Klimaatdijk: Een verkenning

The Climate Dike is a logical addition to the current practice of raising and reinforcing dikes. A Climate Dike is defined here as „a collective term for design components that result in flood defences so robust that they are virtually impossible to breach, and thus offer lasting protection, even in the face of ongoing climate change.. The...

Tijdelijke en flexibele waterkeringen, produktcatalogus

Catalogus van waterkeringen die tijdelijk geplaatst kunnen worden, al dan niet als noodkeringen

Haalbaarheidsstudie naar de toepassing van een worst als tijdelijke waterkering

Het rapport 'Haalbaarheidsstudie naar de toepassing van een worst als tijdelijke waterkering' gaat na of een worst als nooddijk een technisch en/of economisch haalbaar alternatief is voor huidig gebruikte methoden voor tijdelijke waterkeringen. Op dit moment wordt bij dreigend hoogwater op verschillende manieren een nooddijk gebouwd. Men kiest...

Inventarisatie markante verschijnselen aan rivierdijken opgetreden tijdens de hoge Rijnafvoer van februari 1980

Tijdens het hoogwater in februari 1980 als gevolg van de hoge afvoer van de Rijn, is door medewerkers van het Centrum voor Onderzoek Waterkeringen (COW) een inventarisatie uitgevoerd van markante verschijnselen die toen bij de rivierdijken optraden. Een samenvatting van de verzamelde gegevens is in dit rapport opgenomen. Uit de beschikbare...
