Civil engineering infrastructure systems are vulnerable to the effects of natural hazards such as flooding, landsliding, windstorm and coastal erosion. Risk analysis provides a rational approach to analysing the threat that these phenomena pose and identifying efficient options for system management. A general formulation of the risk analysis problem for an engineering system subject to environmental loads is presented. Most of the variables that determine system behaviour may be subject to long term change, for example due to climate change or structural deterioration. Simulation and scenarios analysis provide insights into the performance of systems over extended timescales. The uncertainties in appraisal of infrastructure over extended timescales can be considerable, so a framework is presented for systematic analysis of uncertainties and robust decision making.
