Hydropower scheme operations affect water ecosystems. To reduce the impacts, hydropower producer can use many technical solutions : fish pass, management of floods to transfer coarse sediments downstream or flushing of fine sediments with water release, increase of reserved flow …

Those technical solutions generate a loss of profit for hydropower producers (production of less energy , or production of energy at periods of poor market value for electricity). An economic solution has been developed to quantify this loss of profit and to compensate the producer so as to encourage him to implement environmental solutions.

ROLE OF RIVER MORPHOLOGY ON MITIGATION OF ECOLOGICAL EFFECTS

This is an applied-research, technical solution. Rivers affected by hydropeaking are characterized by extreme variations of numerous physical and chemical parameters. In particular, intermittent releases from hydropower plants result in intense and abrupt variations of water level, velocity, bed shear stress, and temperature, which often occur on daily basis. The unsteadiness related to this highly intermittent phenomenon has cascading effects on the ecological integrity of riverine ecosystems: the biocoenosys change in composition, relative abundance, biomass, and diversity, the drift of benthic invertebrates, as well as the growth and reproduction of fishes are affected.

REUSE OF HYDROPEAKING INTO AN AGRICULTURAL DITCH NETWORK

River reaches in Alpine areas often suffer from strong flow regime alteration due to multiple water uses, with hydropower production frequently playing the most important role for relatively long sections characterized by the propagation of hydro- and thermopeaking waves. The key idea  is that re-using part of the hydropeaking water into the network of agricultural ditches can improve ecosystem health of the river-floodplain system.
