1) The document discusses implementing spillways to existing dykes to reduce flood risk from extreme events. 2) Modeling was conducted to analyze the hydrodynamic consequences and overall flood risk of different alternatives, including the existing scheme and adding a spillway. 3) Results showed that a spillway could reduce the number of people exposed to floods above the dyke's design level, but benefits decreased for larger floods over 1000 years. Combining a spillway with restricted development provided the most effective flood risk management.
