How much water vapour does the Tibetan Plateau release into the atmosphere?
Published 2025-01-01“…<p>Water vapour flux, expressed as evapotranspiration (ET), is critical for understanding the earth climate system and the complex heat–water exchange mechanisms between the land surface and the atmosphere in the high-altitude Tibetan Plateau (TP) region. However, the performance of ET products over the TP has not been adequately assessed, and there is still considerable uncertainty in the magnitude and spatial variability in the water vapour released from the TP into the atmosphere. …”

La mise en œuvre d’un aqueduc : l’exemple de la Brévenne à Lyon
Published 2023-12-01“…The Brévenne aqueduct was neither the first nor the last to be built, but it provided, around the middle of the 1st century AD, the highest flow available at an altitude never previously supplied. The standard of its construction also emphasises the containment of water at a level that would not be equalled in Lyon.On the other hand, its slope is less regular than that of the Gier aqueduct, since maintaining a sufficient height at the base of the flow is not its main concern. …”
