Initial repercussions and hydroelectric developments in the French upper Rhone Valley: a lesson for predictive scenarios propositions

The authors demonstrate the difficulties inherent in predicting vegetation changes in floodplains affected by hydroelectric developments. The results are based on phytoecological studies in the Rhone River valley between Geneva and Lyon. The study is based in a 200-km stretch of river where the floo...

Description
Summary:The authors demonstrate the difficulties inherent in predicting vegetation changes in floodplains affected by hydroelectric developments. The results are based on phytoecological studies in the Rhone River valley between Geneva and Lyon. The study is based in a 200-km stretch of river where the floodplain can attain 10 km in width. Vegetation is described for the area prior to the construction of four dams and compared with the situations 8 yr later. Research methods include systematic sampling of geomorphological, soils, and floristic factors; collection of a data base on spatial information; and large-scale vegetation mapping.
