Can riparian vegetation shade mitigate the expected rise in stream temperatures during heat waves in a pre- alpine river?

摘要: The influence of expected changes in heat wave intensity during the 21st century on temperatures an pre-alpine river are simulated and mitigating effects riparian vegetation shade radiant turbulent energy fluxes analysed. Minor stream water temperature increases modelled within first half century, but a more significant increase is predicted for period 2071–2100. magnitude maximum, mean minimum rises 20 year return event was estimated to be region 3 °C. Additional not able fully mitigate rise caused by climate change, can reduce 1 2° C. Removal existing amplifies increases. Maximum could than 4 °C even yearly events.
