Abstract
The flood risk management policy in The Netherlands focuses on flood
prevention. The current safety standards for the flood defences were developed
in the 1960s in response to the flood disaster of 1953. Because The Netherlands
has changed drastically since the 1960s, the government decided to reconsider
the safety standards. In preparation for a new set of standards for flood
protection, cost benefit analyses and casualty risk assessments are carried out.
The explicit consideration of casualty risks is a new aspect in the flood risk
management policy in The Netherlands.
Casualty risk can be assessed from an individual point of view or from a
societal perspective. Individual casualty risk is related to a person’s probability
to die in a flood. It may be a useful indicator to measure whether a base level of
protection for everyone is provided. Societal casualty risk, or group risk, is
related to the probability of many casualties caused by the same event. Both
viewpoints are considered relevant for discussion on future flood protection
standards.
The paper discusses the background of casualty risks, and their analysis and
assessment in the context of deriving adequate flood protection standards.
Keywords: flood risk management, flood casualties, mortality, flood risks, safety

1 Introduction
The Netherlands is a low-lying country threatened by floods from the sea, large
rivers and from the IJsselmeer, the lake in the centre of The Netherlands. The
northern and western parts of the country consist of low-lying polder areas. The
deepest parts are about 5 to 6m below sea level. In the low-lying western area
