Environmental flows in two highly regulated rivers: the Hawkesbury Nepean in Australia and the Durance in France

摘要: Environmental flows are waters released from storages to improve degraded ecosystems. Subsequent monitoring is then used determine incremental benefits. These in the Hawkesbury Nepean and Durance very low compared with those advocated for other systems. In former, water Sydney Wollongong, while diverted supply 16 hydropower stations. this system, reserved have been set at 2.5% of mean discharge, Australian river, environmental varied, but usually 3.6% or less current regime. Additionally, increasing transparencies barrages weirs will enhance effectiveness flows. Implementation such imposes many problems because structural difficulties releasing compromising regulatory infrastructures. onset global warming, both systems suffer significant losses.
