Floods

The increasing number of intense meteorological events means that flood events are more frequent. Their monitoring is essential to rescue and civil defence authorities, whilst mapping of their extent is widely required by insurance companies.

Sentinel-1's SAR mission supports flood monitoring.

Thematic Results

ESA and China have launched the fourth phase of the collaborative Dragon programme in Wuhan City, on the Yangtze River, which recently experienced major floods witnessed by Europe's Sentinel-1 satellite.
Cyclone Roanu has claimed over 100 lives in Sri Lanka and Bangladesh, and has left tens of thousands in need of aid. Officials are looking to the sky for information on flooded areas to analyse the cyclone's aftermath and support emergency response activities.

With the new Earth observation satellites carrying a range of technologies such as radar and multispectral imaging instruments for land, ocean and atmospheric monitoring, data are available for the next 20-30 years. However, this means little unless there are capable people handling them.

Sentinel-1A's SAR radar instrument has been used to monitor extensive flooding along the Dalton Highway in the state of Alaska, U.S.A.
Sentinel-1 has contributed to aid disaster response efforts in Malawi, following devastating floods which have affected the south African nation in January 2015.

A wing for Sentinel-2A

Imaging Earth's land with unprecedented speed and resolution has come another step closer as the next Sentinel satellite has been given its solar wing and started a strenuous six-month test campaign to make sure that it is fit for launch next April.

Following a contract signed with Arianespace today, the second Sentinel-1 satellite is now set to join its identical twin sister in orbit in early 2016, optimising the mission's global coverage to manage the environment and improve everyday lives.

Calling all app developers: register today for the opportunity to spend a week at ESA developing new ideas and concepts for mobile apps using satellite Earth observation data.

As ESA and China mark a decade of cooperation, imagery over China's Poyang lake is testament to the new Sentinel satellite's promise of continued radar data acquisition for a multitude of applications.

Although not yet operational, the new Sentinel-1A satellite has provided radar data for mapping the floods in Bosnia and Herzegovina.

While Sentinel-1A is clearly demonstrating its versatility for monitoring many aspects of Earth, it has already been used for practical purposes. One of the satellite’s first images was crucial in helping Namibian authorities decide how to respond to a serious flood.

From climate change monitoring to supporting humanitarian aid and crisis situations, early data applications from the month-old Sentinel-1A satellite show how the radar mission's critical observations can be used to keep us and our planet safe.

Sentinel-1A, Europe's first satellite for Copernicus, is almost ready for launch on 3 April. Meanwhile, ESA is showing how its advanced radar will map ice, monitor subsidence and much more.

Building on its use of satellites for responding to disasters, ESA has helped to create a service that makes flood maps available simply via the Internet.

The effects of climate change, population growth and economic development in the Mediterranean are posing a threat to the water supply in the region. As part of ESA's TIGER initiative, satellite data are supporting water management by identifying water resources.

GMES for Europe

12 October 2012

The potential of GMES for crisis management and environmental monitoring is highlighted in a new publication with users demonstrating the importance of Earth observation data to European regions.

The use of data from Earth-observing satellites in the insurance business is still in the early stages, but pressure to be ready for more frequent extreme-weather events is increasing.

The risk of natural disasters can be reduced by understanding our environment and the fundamental forces that shape it. Earth-observing satellites can provide vital information to mitigate and prepare for disasters.

Earth-observing satellites can map natural phenomena such as floods and earthquakes, track hurricanes and monitor land subsidence across the globe. This information can be valuable to insurance companies for risk and damage assessment.
