| Zusammenfassung |
| Decision makers in fluvial flood risk management increasingly acknowledge
that they have to prepare for extreme events. Flood risk is the most common
basis on which to compare flood risk-reducing strategies. To take
uncertainties into account the criteria of robustness and flexibility are
advocated as well. This paper discusses the added value of robustness as
an additional decision criterion compared to single-value flood risk only. We do
so by quantifying flood risk and system robustness for alternative system
configurations of the IJssel River valley in the Netherlands. We found that
robustness analysis has added value in three respects: (1) it does not
require assumptions on current and future flood probabilities, since flood
consequences are shown as a function of discharge; (2) it shows the
sensitivity of the system to varying discharges; and (3) it supports a
discussion on the acceptability of flood damage. We conclude that robustness
analysis is a valuable addition to flood risk analysis in support of
long-term decision-making on flood risk management. |
