This map illustrates a time series analysis of the evolution of satellite-detected surface waters in Sanamxay district, Attapeu province, based on satellite data collected on 13, 25 and 29 July 2018. Within the current map extent, on 13 July 2018, before the collapse of the dam, a total surface of 47,717 ha was detected as inundated and the reservoir controlled by the dam was full of water. As of 25 July 2018, two days after the dam collapsed, an additional surface of 7,531 ha of inundated areas were detected, representing an increase of the surface waters of 16%.

Situation overview & potential additonal flooded areas after the collapse of the Xe-Namoy dam, river overflow and heavy rain. The derived product illustrates the evolution of the event upstream and downstream Vang Ngao and Xe Kong rivers. Close-up view insets using Sentinel-1 imagery collected on the 13 and 25 July shows comparison between these dates. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.

Thanks to the European Union’s Copernicus programme, vast quantities of satellite data are freely available to manage the environment and benefit European citizens. While this offers a wealth of opportunities, downloading and storing these data involves some complex logistical challenges – but this is about to change.

With such a lot of data available, the European Commission is making efforts to make sure that the process of accessing these data and information is easier so that issues associated with downloading and storing can be avoided.
