River rehabilitation from the Hydrogeomorphic impacts of a large hydro-electric power project: snowy river, Australia

摘要

Large interbasin water transfers for hydro-electric power generation have substantially changed the hydrology of the Snowy river below the Snowy Mountains Hydro-Electric Scheme in southeastern Australia, since 1967. Annual, Monthly, mean daily and peak instantaneous flows have been significantly reduced and flood variability greatly Increased along 352 km of channel. The first 70 km of river has responded by substantial contraction through the Reworking of tributary mouth bars into downstream pools, bars and benches.
