Abstract
In this paper we study the well-posedness for a scalar conser-
vation law in which the flux term is non-local in space.
This equation represents a reduced model for slow erosion in
granular flow ([1, 6]) and describes roughly the evolution of a
profile of stationary matter, under the effect of a thin moving
layer of granular matter on the top of it.
We show that the present equation admits weak solutions ex-
isting globally in time and prove their stability w.r.t the initial
