    Unser Wasser digital erforschen?

    Der Klimawandel bestimmt auch den Zustand unserer Gewässer. Damit wir uns besser darauf einstellen und vorbereiten können, braucht es jede Menge Daten von Flüssen, Bächen oder Seen auf der ganzen Welt. Diese lassen sich mit der CrowdWater App sammeln. Sie wurde im Kinderkanal des deutschen Fernsehens vorgestellt.

    New paper published

    Aline Meyer Oliveira, Ilja van Meerveld, Marc Vis and Jan Seibert published a paper entitled "Assessment of the Value of Remotely Sensed Surface Water Extent Data for the Calibration of a Lumped Hydrological Model" in Water Resources Research.

They found that the main limitation was the coarse spatial resolution of remote sensing imagery, and not its limited temporal resolution.

  • Heisse Sommer - feuchte Winter

    Der Klimawandel hat Auswirkungen auf die Wasservorkommen in der Schweiz. Am deutlichsten ist die Verschiebung der Niederschläge von Schnee zu Regen, wodurch es zu einer Verlagerung in der zeitlichen Verteilung des Abflusses kommt. Darüber hinaus wird die Schweiz indirekt auch von Veränderungen der weltweiten Wasserverfügbarkeit betroffen sein. Beitrag von Jan Seibert in "aqua viva" Nr. 3/2019, Themenheft "Gewässer in Zeiten des Klimawandels".  Die Artikel der aqua viva finden Sie hier .
