Behaviour Of Debris Flow Material In The
Campania Region

Abstract
The rheological behaviour of the natural material collected in the source area of
three debris flows occurring in the mountainsides of the North-western
Campania region (southern Italy) has been investigated. The tests have been
carried out at different solid volumetric concentration Cv with a standard
rheometer equipped with two geometric configurations to avoid disturbing
effects. All materials behave like a Non-Newtonian fluid with a threshold shear
stress τy (yield stress) that increases with solid volumetric concentration. The
experimental data have been fitted with standard model generally used for fluids.
A simple relation between Cv and τy has been obtained.
Keywords: rheology, debris flow, pyroclastic soils, laboratory activity, fluids
model, yield stress.
