Abstract
We study the stability of shallow layers of granular materials conside red as Bagnold fluids (the fluid with power law exponent n = 2) in two cases: (i) inertia terms are negligible and (ii) inertia terms are im portant. The linear analysis of the governing equations in the two cas es demonstrates stable and unstable regimes, respectively. The evoluti on of some finite amplitude disturbances is solved numerically.
