The Cost of Risk Aversion: Eliciting risk preferences and re-evaluating flood protection standards in the Netherlands

Where water flows, prosperity follows.<br/><br/>Many prosperous areas around the world are situated near large bodies of water such as oceans, seas, and rivers. These bodies of water play a vital role in enhancing the prosperity of societies through various means. They provide convenient access to transportation, food, recreation, and many other...

Feasibility of the Polders: When can the Dutch polderconcept become economically unviable?

Adequate flood protection is important to many countries, but especially so to the Netherlands. With a large share of its population centers located below sea level, in so-called polders, the need for flood protection systems quickly becomes apparent. This need is even more pressing with the rise of sea levels and the increase in river discharge...

Impact assessment for the area of dikering 14 under the influence of sea level rise

Climate change is a major problem for today's society, which has a huge impact on water safety issues. Recent IPCC scenarios show that sea level rises of 1m by 2100 and 2m beyond 2200 should be seriously considered. Several scenarios show an increase in river discharge of between 10 and 20 percent of the Rhine generated by extreme precipitation...

Assessment of changes in flood risk in South Holland due to sea level rise: How can the dunes of dijkring 14 cope with sea level rise?

Economic risk due to a potential flood event is determined by combining the estimated damages and the probability of failure for many scenarios. In recent research of the IPCC (Intergovernmental Panel on Climate Change) it was stated that the sea level will rise more than expected due to climate change . This could influence the flood risk in...

The missing link in adaptive delta management: Insights on the potential of pumps in reducing flood risk under sea level rise and adaptive social learning to improve decision-making in the Rhine-Meuse estuary

Decision-makers in low-lying coastal zones are confronted with uncertain developments around flood risk.These drivers are surrounded by large uncertainties, which requires delta management to be adaptive. This research offers insights about adaptive delta management for the Rhine-Meuse estuary from three perspectives: a physical, a socio...

Quantification of the Uncertainties in river discharges due to Climate Change: And the consequences for flood protection designs in The Netherlands

Changes in the Earth’s climate system do have consequences for the river discharges. The development of the future climate is uncertain, which causes uncertainty in the future extreme river discharges. For flood protection considerations, it is important to quantify the climate uncertainties and its effects on extreme river discharges. In this...

Foreshores in the Wadden Sea

Dutch flood protections are assessed every five to six years in a nationwide safety assessment round. During the last assessment round large dike stretches in the Dutch Wadden Sea could not meet the safety requirements, and were assessed with failure. Dike strengthening is therefore needed in these areas. However, in front of these dike salt...

Identifying Delta Regions Most Vulnerable for Flooding: A Multiple Land Use Flood Risk Assessment for Australia

The global economical losses caused by flooding have increased over the last 50 years (IPCC, 2014; UNISDR, 2013). Deltares and HKV are developing new methods to quantify flood risk on a global scale. A Flood Risk Assessment Tool (FIAT) is used to performcalculations. The definition of risk is hazard x exposure x vulnerability. FIAT is able to...
