This study provides an overview of the impact of the 2021 Summer floods in the Netherlands and the assessment of the effectiveness of various adaptation measures, evacuation strategies, and their impact on society. The floods were characterized by record rainfall in the cross-border region of the Meuse and Rhine basins and resulted in...

In response to the outbreak of SARS-CoV-2, many governments decided in 2020 to impose lockdowns on societies. Although the package of measures that constitute such lockdowns differs between countries, it is a general rule that contact between people, especially in large groups of people, is avoided or prohibited. The main reasoning behind these...

In juli 2021 zijn grote delen van Limburg getroffen door hevige regenval en overstromingen. Ook delen van België en Duitsland overstroomden met zeer veel schade en verlies aan mensenlevens tot gevolg. Dit betrof een extreme en ongeëvenaarde gebeurtenis met enorme impact. Daarom is naar aanleiding van de overstromingen deze verkenning uitgevoerd...

Sinds het Deltaprogramma zijn risicobenadering en rampenbeheersing definitief ingebed in het waterveiligheidsbeleid. Echter, in een koppeling tussen deze twee is nog veel winst te behalen, betoogt Bas Kolen; vooral voor de systematiek van opschalen, het moment om maatregelen te nemen en manieren om maatregelen beter te kunnen uitleggen. De...

It is important for decision-makers in emergency response situations to determine the scope, scale, timing, path and resettlement area of an evacuation decision when there is an imminent threat of flooding. In this paper, a method called the "Evacuation Diagram" is described to support risk-based evacuation planning and decision-making. In...

An analysis was made of the loss of life caused by Hurricane Harvey. Information was collected for 70 fatalities that occurred due to the event and were recovered within the first 2 weeks after landfall. Most fatalities occurred due to drowning (81 %), particularly in and around vehicles. Males (70 %) and people over 50 years old (56 %) were...

On August 25, 2017, Hurricane Harvey made landfall near Rockport, Texas as a Category 4 hurricane with maximum sustained winds of approximately 200 km/hour. Harvey caused severe damages in coastal Texas due to extreme winds and storm surge, but will go down in history for record-setting rainfall totals and flood-related damages. Across large...

To help decision makers in delta areas to select appropriate adaptation and mitigation strategies it is necessary to have a clear picture of the main drivers of risk and how risk evolves under changing conditions. Acknowledging these problems, the Delta Alliance and the TU Delft took the initiative to develop a new index that helps cities to...

An integrated flood risk management (IFRM) strategy consist of a comprehensive set of measures to reduce the risk: protective measures (to reduce the probability of a flood), and land use planning and disaster management (to reduce the consequences of a flood. In the Netherlands this is called a ‘multiple layer safety approach’, other countries...

The central issue for authorities (as well as the public) is how and when to respond to forecasted extreme water levels on rivers, lakes and along the coast and large-scale flooding is an actual risk. The decision-making process is influenced by contradicting information, overloads and gaps in information, rumours, uncertainties in forecasts,...

Design-criteria for flood-defences have a legal character in the Netherlands. Formerly, these flood protection standards were based on design-waterlevels, where a flood defence was implicitly supposed not to fail below this waterlevel. Since knowledge regarding dike-failure improved, a new risk approach has been developed based on a social cost...

This paper presents an overview and review of methods developed for loss of life estimation in flood risk assessment. These methods range from empirical to simulation based approaches that are used to support flood risk analyses and emergency management. Similarities and differences between the modelling approaches, input and output types and...

Both in the USA and in the Netherlands, extensive studies on approaches for identifying flood risks (the combination of levee failure probabilities and consequences) are ongoing. A related topic concerns evacuation and emergency management (EEM). The magnitude of life loss is directly influenced by the effectiveness of EEM. Different models can...

In this research vertical evacuation is defined as the displacement of people to dry floors in buildings or public shelters that are located inside the threatened or flooded area. Vertical evacuation strategies can be implemented in combination with, or as an alternative to, preventive evacuate in case preventive evacuation is not entirely...

In the Netherlands, USA and other countries methods for the analysis of loss of life and evacuation associated with flooding are used in flood risk management. This paper compares the methods from the US and Netherlands in this field and considers both methodological principles as well as the outcomes for various case studies. Similarities and...

This paper presents an assessment of the multi-layered safety system in Tohoku, Japan based on the tsunami disaster of March 2011. The performed analysis has been based on data provided by local researchers and field observations. First an overview of the tsunami behaviour along the affected coastline of Tohoku is presented, which shows clearly...

We claim that, in The Netherlands, emergency management for flooding should be seen as an ‘add on’ to existing emergency planning. Therefore, some specific preparation is required to minimize loss of life and maximize the use of available information, resources and infrastructure. This booklet discusses this preparation based on the experiences...

Op 28 februari 2010, rond 2 uur in de ochtend, bereikte de storm Xynthia de westkust van Frankrijk. Op meerdere locaties bezweken de waterkeringen, met kustoverstromingen tot gevolg. Meer dan 50.000 hectare aan land overstroomde. In totaal vielen in Frankrijk 47 doden, de meesten door het water en een enkeling door de gevolgen van de storm....

On the 28th of February 2010 at 2 a.m. the storm Xynthia hit the French Atlantic coast. The storm surge combined with the high tide and large waves caused flood defences to fail along the coastline from the Gironde (Bordeaux) to the Loire Estuary. A significant amount of land, (>50 000 ha) was consequently flooded and 47 people died as a result...
