Reappearance of the Dnieper river after the destruction of Kakhovka dam

The Kakhovka Reservoir was created in 1956. As the level of the reservoir drops at a staggering rate of two meters per day, it is now possible to see the ancient river reappear in satellite images.

I have georeferenced a 1943 German military map published by Defense Express in their article « 1943 Maps Show What Ukraine’s Kakhovka Reservoir Will Look Like When the Waters Settle Down » to verify if the Dnieper returns to its original state before the dam was constructed.

The former river is also visible near the Zaporizhzhia Nuclear Power Plant. According to the French Institute for Radiation Protection and Nuclear Safety the dikes of the cooling pond can withstand a Dnieper level of 10 m in the vicinity of the power plant. The level reached 11.8 m on June 9. It should be already well below 10 m by now but the cooling pond remains full.

The lake water level can be monitored by satellite altimetry in Theia’s HydroWeb website. However, the data are no longer updated due to the lack of water to reflect the signal emitted by the altimeter.

Dates de fauche en France

En 2024, des collègues du Cesbio ont publié un article* sur la cartographie de la date de fauche en France en 2022 à partir des données satellitaires Sentinel-2.   Leur magnifique figure 10 a attiré mon attention. La version à haute résolution fournie avec l’article (2861 × 2911 pixels) correspond à une image dont les pixels font […]

Évolution du jour de déneigement dans les Alpes françaises et les Pyrénées

Les socio-écosystèmes des Alpes et des Pyrénées dépendent étroitement des fluctuations annuelles du manteau neigeux. En particulier, le moment de l’année où la neige disparait détermine le début de la saison de croissance de la végétation de montagne et donc la période des estives. Le changement climatique est en train de bouleverser ce rythme saisonnier. […]

BIOMASS, the third launched satellite mission designed at CESBIO !

After SMOS in 2009, and VENµS in 2017, the CESBIO laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]
