In the Massif Central, the upper Loire river is influenced by hydroelectric works. Measurement of the effects shows a major impact on hydrological conditions on an annual, monthly and daily basis, as well as the elimination of medium and small-scale floods. As resources of sediments have dried up, due to reafforestation, gravel extraction and embanking works, for more than a century the Loire's river bed in the Forez area has become further entrenched. The dams associated with the hydro-electric schemes have accentuated this process by reducing the transport of bed load, drying out the substrate and considerably reducing the necessary upply of coarse material. A restoration programme designed to pave the river is envisaged although not yet started despite its urgency. Source : Éditeur (via Persée) |
