The Danube River is one of the most important trade routes in Western Europe. Along with all other major European rivers, it has been strongly affected by the consequences of the extreme drought conditions ongoing in Europe. In some parts of western Europe, in fact, the Danube is unnavigable. On 12 August, the water level at Tulcea, in Romania, stood at 51 cm (data from the Danube Fairway Information Service Portal), a value which is 6 cm lower than the minimum value required for navigation, and dredging is currently being performed to allow the river circulation.
With an average revisit time of five days at the equator, the Copernicus Sentinel-2 satellites provide free and open data that can be used to monitor drought and its impact on ecosystems or infrastructure.
