A variety of features are observed when sand is supplied steadily on a rough unconfined slope. Over a range of intermediate slope angles, a densely packed layer of finite width and critically shallow depth develops and flows downstream. Isolated avalanches form periodically for input fluxes below a sufficiently small value. The experimental results will be presented and explained by theoretical ideas.
