Real-time information for flood event management

World-wide flood disasters account for about a third of all natural disasters, by number and economic losses. The death toll in 2013 was 10,000 people. The economic damage in 2013 caused by flooding was 50 billion US dollars (Munich RE). Climate change will increase the probability of extreme events, whereas population growth and economic development, especially in delta areas, will increase the potential impact of flooding. Government authorities carry a huge responsibility. A solid operational flood management infrastructure will allow governments to respond effectively, avoiding damage and saving lives.

Right information at the right time

The question is: how can government authorities be accurately informed when a flood is about to occur? And how can they inform all the parties and people involved, with the right information at the right time to allow for an appropriate response?

Tailor made approach

Deltares has a vast amount of expertise in the field of operational flood management, linking disciplines such as hydrology, hydraulics, dike technology, mathematics, probabilistics and soft skills in communications and social sciences. As a result, we are in a position to create new concepts and tools that target our clients’ needs, providing actual, accurate, reliable and practical information that can be used in flood situations. Together with our clients we tailor our approach to include and make use of existing tools and data streams, and to develop new capabilities. Our Delft-FEWS software, for example, provides an open shell that maximises the potential for comprehensive and effective flood forecasting.

Emergency response measures

Deltares also provides advice about emergency response measures, using forecasts and flood scenarios to make sound and effective decisions about which measures to take. An essential feature of our consultancy work is our sound understanding of the needs of both decision-makers and responders, including the addressing of uncertainty in the information at hand.

Forecasting systems

We provide specialist consultancy services and we engage in research worldwide. Our Delft-FEWS software has been implemented in over 35 countries and in many cases (such as the USA, England & Wales and the Netherlands) it is the official national flood forecasting system. Further to the development of flood forecasting systems for predicting river discharges and water levels, Deltares has also developed a tool, DAM Live, to assess the strength and stability of flood defences, which has been implemented in the Netherlands and China.

24/7 emergency response consultancy service

These tools allow decision-makers to make sound and effective decisions and allow responders to carry out the required measures. In numerous countries, Deltares has also provided specialist advice during major flood events, such as the Thai floods of 2012. In the Netherlands, Deltares also provides a 24/7 emergency response consultancy service, with up to 150 experts, for the Dutch government. Internationally, Deltares key experts are listed for European Union emergency missions.
