Screening flood adaptation measures framework

To reduce the flood risk in areas prone to flooding, possible adaptation measures must be investigated. In this thesis a Python-based framework has been developed that can screen flood adaptation measures as an alternative to the existing analytical method of Royal HaskoningDHV. The framework is limited to the costs and effects on the economic...

Optimal system safety targets: Incorporating hydrodynamic interactions in an economic cost-benefit analysis for flood defence systems

Historically, people in flood-prone areas world-wide have (to a certain degree) accepted the risk of being flooded because of the benefits that flood-prone areas can provide; examples of such benefits are rich agricultural lands or trade advantages. Acceptance and benefits notwithstanding, people living in flood-prone areas have tried, and will...

Economic optimization of flood prevention systems in the Netherlands

After the flood disaster of 1953, the Netherlands adopted a rational approach to flood risk management with the use of protection standards determined by means of cost-benefit analysis. Due to scientific and political developments that have recently taken place, an update of the Dutch protection standards is being undertaken. One of the major...

Flood risk analysis for metropolitan areas – a case study for Shanghai

In Shanghai, the main threat to the city’s safety is a typhoon induced storm surge in combination with a high astronomic tide in the Huangpu River. Historical flood events have shown that the weakness of the floodwall, with potential overtopping and breaching along the Huangpu River and its branches, has caused great economic damage and loss of...

Effectiveness of sensors in flood defences

Introduction The popularity of monitoring dikes with sensor techniques is rising. It is claimed that sensor techniques lead to significant cost savings and can predict an upcoming dike collapse. But a technical foundation to use the sensor monitoring information in flood safety assessment is lacking. This research investigates the contribution...

Veiligheid tegen overstromen: Kosten-batenanalyse voor Ruimte voor de Rivier, deel 1

This report is part 1 of a Cost-Benefit Analysis of the project ‘Space for the Rivers’, which aims at improving the safety against flooding along the river Rhine. A new method has been developed to find the optimal safety level for dike rings against flooding and the accompanying investment strategy. This method has been applied to 22 dike rings...
