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...

A hybrid solution for the Galveston Seawall: A study on the reduction of the hydraulic loads by a sand cover at the Galveston Seawall with the use of XBeach

The City of Galveston is protected from extreme storm impact by a 17-km concrete seawall facing the Gulf of Mexico. Recent investigations have shown that the seawall may not be sufficient any more to protect against a 1 in 100 year design storm. Since raising the seawall disconnects the city from the beach and may be very costly, a hybrid...

Man-made lowlands, a future for ancient dykes in the Netherlands

Dikes are part and parcel of the Netherlands. Down through the centuries they have played a role in every attempt to make this country inhabitable – in the reclamation of peatland and marshland, as coastal embankments and to enclose polders and flank rivers. This means they are often cultural heritage features of the highest order as they have...

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...

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...

Verlauf des Rheines von Basel bis Mainz: Übersichtsdarstellung mit Hochwasserschutzsystemen

Maps of the Rhine section between Basel and Mainz including the flood defence system.

Sea Defences

The increased demand on reliable design methods for protective structures has resulted in the Netherlands in preparing a set of design guidelines for revetments of the sea-, and river-dikes, and for bank protection. These guidelines are intended for technicians and organizations directly involved in the design and management of protective...
