Mesure et interprétation du processus d'érosion dans les marnes des Alpes du Sud à l'échelle de la petite ravine
Measurement and interpretation of the erosion process in South Alps maris, at the scale of a little gully
In the experimental catchments of Draix (Alpes-de-Haute-Provence), the erosion of black marls of South Alps are studied.
When the measurement devices of the smallest basin (1 330 m2) has been presented, the quality of the data is examined in order to select those which are usable. After a qualitative analysis of erosion process, the results of erosion measurements are explained by: detection of thresholds of run-off and erosion (taking care of previous situation); multiple regression with rainfall intensity, kinetic energy of rainfall (Wishmeyer, etc...), discharge, etc... at the scale of an event and at the scale of the season.
