Essai de synthèse des connaissances en érosion et hydraulique torrentielle

Attempt of synthesis of the knowledge in mountain erosion and torrential hydraulics

CEMAGREF, Grenoble

Abstract

The introduction makes explicit what should study erosion and hydraulics sciences in mountain catchments; then, characteristics and methods of torrential erosion are described, as well as research projects which are going on in France. In a second part, are explained the differences between torrential and classical hydraulics; then, two theories used for debris flows, and at last a set of formulas which allow the engineer to compute solid and liquid discharge as well as the stage of the mixture in erodible torrents.
