Abstract

This paper deals with a laboratory and numerical research on mudflows performed in with the aim to study the interrelations between the grain-size composition of the mud and its rheological properties at different solid concentrations. Furthermore, the predicting capability of a new numerical model in reproducing the flow of viscous materials is evaluated.

Keywords

Mudflows Viscous materials Run-out model Grain-size composition
