Résumé anglais |
The functioning of running water ecosystems is controlled by the interaction of several physical parameters, the knowledge of which is beiing improved. Currently, the CEMAGREF, LYON, is developing a methodology allowing the description and the modelling of three of these parameters which have been selected on the basis of their importance for the biotic communities.namely, i stream velocity, ii water depth, Hi bed material. A division of the study reach into discrete cells provides a differenciated picture of the spatial variability of the hydrodynamic parameters measured at a given discharge, the mathematical modelling of water level integrates time variability. A reach on the Filliere river (Northern French) examplifies this method. Source : Éditeur (via Persée) |
