Evaluation of grain shear stresses required to initiate movement of particles in natural rivers

Auteur :
PETIT, F.

Description :
Observations are made in two small rivers (the Rulles and the Rouge Eau) differentiated both by the nature of their load and their discharge regime. Shear stresses calculated from friction velocities at the sites where erosion actually occurred (or failed to occur despite very high velocities) provide a good explanation of the observed movements.
