Abstract
To carry out a functional typology of a Normandy watercourse, three compartments (water quality, physical features and macrophytes) were studied in 74 stations. The data were analysed with multidimensional methods: Principal Component Analysis (P.C.A.), Hierarchical Cluster Analysis (H.C.A.) and Multiple Factor Analysis (M.F.A.). P.C.A. analysis of the 3 compartments ordered significant variables as following:
-
– stream order, water velocity and light,
-
– conductivity, pollution parameters as opposited to mineralisation ones,
-
– upstream/downstream, sciaphilous/heliophilous, rheophilous, ditch species.
