The global functioning of a stream must be known if its management is to be improved. However, it's often impossible to undertake a detailed study of the whole stream and its watershed due to contraints of time and cost. The use of functional typology enables the identification of different reaches, each with its one functional characteristics, and the selection of representative sites for more detailed study. This approach involves a synthesis of standard geomorphological and hydrobiological data. Large reaches and the variables for their identification are shown by a descriptive and objective analysis. These variables are slope, bankfull width and watershed geology. This result proves that "specific strength" calculation is an appropriate tool for longitudinal classification. The functional typology allows management methods to be adapted to each reach : an example of this method is provided by the Vidourle, a mediterranean coastal river in Languedoc.
