Abstract

This paper is concerned with experimental results of sand avalanches flowing down inclined plexiglass chutes with lateral confinement. We introduce the Particle Image Velocimetry (PIV) technique for granular avalanches and discuss the differences in its implementation compared to standard PIV. Surface and side-wall velocity measurements are described at different downslope chute locations and for four different inclination angles. The PIV-system provides a good measuring technique to determine flow velocities of granular avalanches. The flow behaviour for the smallest inclination angle investigated here deviates significantly from the other results as the avalanche reaches a terminal velocity. This gives valuable indications for the right choice of a bed friction law. © Springer-Verlag Berlin Heidelberg 2003.
