Abstract

Granular heaps of particles created by deposition of mono-disperse particles raining from an extended
source of finite size are characterized by a non-homogeneous field of density. It was speculated that this
inhomogeneity is due to the transient shape of the sediment during the process of construction of the
heap, thus reflecting the history of the creation of the heap. By comparison of structural characteristics of
the heap with sediments created on top of inclined planes exploiting the method of Minkowski tensors,
we provide further evidence to support this hypothesis. Moreover, for the case of sediments generated by
homogeneous rain on surfaces, we provide relationships between the inclination of the surface and the
Minkowski measures characterizing the isotropy of local particle environments.
