Safety Assessment Method of Flood Defences for Flow Sliding

Flow sliding of submerged slopes in front of dikes can affect the reliability of flood defences. The occurrence of flow sliding may result, sometimes with delay, in a failure mode and consequent flooding. The current safety assessment method for flow sliding does not consider the interaction between flow sliding and failure modes which can cause...

An integrated approach to flood risk management and spatial quality for a Netherlands’ river polder area

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...

Influence of load interdependencies of flood defences on probabilities and risks at the Bovenrijn/IJssel area, The Netherlands

In the Netherlands, flood risk analysis is usually carried out for a location, without considering potential flood defence failures in upstream areas. This may result in significant over- or underestimation of flood risks. The effect of upstream failures on failure probabilities and flood risks in other areas is called load interdependence of...

Effectiveness and reliability analysis of emergency measures for flood prevention

During flood events emergency measures are used to prevent breaches in flood defences. However, there is still limited insight in their reliability and effectiveness. The objective of this paper is to develop a method to determine the reliability and effectiveness of emergency measures for flood defences. The investigation is focused on measures...

Effectiveness and reliability of emergency measures for flood prevention

Floods in the summer of 2013 in Central Europe demonstrated once again that floods account for a large part of damage and loss of life caused by natural disasters. During flood threats emergency measures, such as sand bags and big bags, are often applied to strengthen the flood defences and attempt to prevent breaches. Although these measures...

Economic implications of multi-layer safety projects for flood protection

Recent experience of large-scale water disasters such as Hurricane Katrina in 2005 and the Great Eastern Japan Earthquake and Tsunami in 2011 has reminded mankind that disasters cannot be ruledout. Unprecedented low-probability events can happen even in the most well monitored areas, causing major social-economic disruption. Failing to prepare...

Assessment of the losses due to business interruption caused by large-scale floods

The economic consequences of floods, both in the form of material damage and losses due to business interruption, can be large. This paper presents a comparison between two approaches to determine the losses due to business interruption caused by large-scale floods. A model (HIS-SSM) containing a damage function approach and an Adaptive Input...

Dutch approach to flood risk management for La Mojana in Colombia

Moveable flood barriers in the Rhine-Meuse estuary

It is possible to reduce flood risk in estuaries without having to drastically modify the river banks by levees or to block shipping routes and ecological flows by dams. ‘Storm surge barriers’ close off a river mouth at times of high sea water levels, but keep the river open during calmer times. ‘Moveable river flood barriers’ direct a river...

Analysis of pluvial flood damage based on data from insurance companies in the Netherlands

Insurance databases form a promising data source that can be used to improve pluvial flood damage estimations. This paper describes the key characteristics of an insurance database on water related damages to private buildings and content in the Netherlands that has been made available for research. The paper presents preliminary results of a...

Coastal defence cost estimates: Case study of the Netherlands, New Orleans and Vietnam

This study is part of a global study on the costs of adaptation to the effects of climate change. It adds information from three specific case studies (the Netherland, New Orleans and Vietnam) to the global study. The case study areas are comparable by type of coast; all are low-lying deltaic coastal areas. This study investigates the unit cost...

Schade door overstroming: Ervaringen uit New Orleans

Korte samenvatting van de overstromingen door hurricane Katrina in augustus 2005 in New Orleans en omgeving. Beschrijving van de effecten op het gebied en de bewoners, kwantitatieve inschatting van de gevolgend, en wat we hieruit voor Nederland kunnen leren. Uitgave met ondersteuning van het Ministerie van Economische Zaken.

Prefabrikage van een getijdencentrale in het Severn Estuarium, Groot Brittanie

In dit hoofdontwerp is gepoogd om uitgaande van de funktionele eisen en de randvoorwaarden te komen tot het ontwerp van de turbine-eenheid. Allereerst wordt de getijdencentrale gesplitst in een aantal komponenten, elk met een specifieke funktie, en wordt het trace bepaald. Vervolgens wordt de komponent met de genererénde funktie nader uitgewerkt...
