For a long time, natural conditions prevented TRANSWAT project experts (V. Šarauskienė, D. Meilutytė-Lukauskienė, S. Nazarenko) from removing water level sensors from a flooded river. After the flood subsided, we finally managed to do it. Researchers will now be able to see the impact of the hydropower cascade on water level fluctuations in the Varduva River.
