Assessment of ductile dike behavior as a novel flood risk reduction measure

Dikes are an effective flood risk reduction measure in deltaic areas. Present risk analyses consist often of decoupled calculations of probabilities of dike failure and calculation of consequences of flooding given dike failure. However, the flood defense design determines not only the probability of failure, but influences the consequences...

Economic optimization of flood prevention systems in the Netherlands

After the flood disaster of 1953, the Netherlands adopted a rational approach to flood risk management with the use of protection standards determined by means of cost-benefit analysis. Due to scientific and political developments that have recently taken place, an update of the Dutch protection standards is being undertaken. One of the major...

Effectiveness and reliability of emergency measures for flood prevention

Floods in the summer of 2013 in Central Europe demonstrated once again that floods account for a large part of damage and loss of life caused by natural disasters. During flood threats emergency measures, such as sand bags and big bags, are often applied to strengthen the flood defences and attempt to prevent breaches. Although these measures...

Basisvisie afwegingsmethodiek voor meerlaagsveiligheid

STOWA werkt in het kader van het kennisprogramma Deltaproof aan de ontwikkeliling van een afwegingsmethodiek voor een hanteerbare uitwerking van meerlaagsveiligheid, met het oog op een brede toepassing door waterbeheerders binnen Nederland. Het doel van deze notitie is het neerleggen van een basisvisie meerlaagsveiligheid. Deze basisvisie vormt...

Moveable flood barriers in the Rhine-Meuse estuary

It is possible to reduce flood risk in estuaries without having to drastically modify the river banks by levees or to block shipping routes and ecological flows by dams. ‘Storm surge barriers’ close off a river mouth at times of high sea water levels, but keep the river open during calmer times. ‘Moveable river flood barriers’ direct a river...
