The economic evaluation of adaptive pathways for flood risk reductions strategies

Climate change and its impacts have necessitated a shift from relying solely on mitigation measures to implementing effective adaptation strategies. The financial requirements for adaptation, particularly in developing countries, have increased substantially. The annual projected needs for adaptation have nearly quadrupled over the past decade...

Assessing economic risk, safety standards, and decision-making

Risk-informed decision-making needs methods for assessing flood risk, and often the flooding probability and the consequences of floods (such as economic damage and fatalities) play an important role in the risk assessment. Also, measures to reduce the flood risk need to be formulated, in order to make a risk-informed decision, whether to...

Effectiveness of Mangroves in Flood Risk Reduction

The risk of flood risk is increasing with global trends such as rising sea levels, land subsidence, increasing populations in coastal areas and economic growth. Traditional solutions to reduce flood risk are a levee or a dam; however, the research on hydraulic engineering is increasingly promoting nature-based solutions for flood protection....

Impact of including interdependencies between multiple riverine flood defences on the economically optimal flood safety levels

In risk analysis of riverine flood defence systems, sections of flood defences are often considered separately, herewith ignoring their interdependence, e.g. due to the hydraulic response following dike breaches in the system. In previous studies it has been found that such interdependence can have a significant influence on flood risk estimates...

Economic optimization of coastal flood defense systems

Coastal flood defense systems can consist of multiple lines of defense. In case of a system with a front and a rear defense (e.g. a storm surge barrier and levees), the front defense can improve the reliability of the rear defense by reducing the load on this rear defense. This paper develops a framework in order to assess whether including...
