RHONE RIVER DEVELOPMENTS
Multipurpose development :Hydroelectricity: 19 HPP, 3.000 MW, 16 TWh/y
Navigation: 330 km large gauge waterway, 14 locks
Harbors and industrial areas: 28, 120 million tons x km, multimodal platforms (inland and maritime, railway, roads, pipeline)
Irrigation: 120.000 ha
Flood control: 40.000 ha protected, 400 km of embankments, maintenance and control of flood runof capacities
Environment: restoration of river works
Catchment area: 100 000 km2
Length: 517 km in FranceAverage discharge : 400 m3/s to 1.700 m3/s 1000-year Flood:2.500 m3/s to 14.000 m3/sLargest flood recorded: 12.500 m3/s (2003)
