      Monitoring of the Kakhovka reservoir/river by altimetry

      2023-06-22

      The Hydroweb database – https://hydroweb.theia-land.fr/ – is monitoring changes in water levels over time on large lakes, reservoirs and rivers, from altimetry measurements. Hydroweb was not originally designed to monitor the degradation of reservoirs, either naturally or as a result of destruction, such as at the Kakhovka dam on the Dniepr river. Although it did provide relevant and accurate information on the evolution of the reservoir in the days following its recent explosion. These ...
