Abstract: To predict mudflow dynamics a numerical model based on shallow-water equations is developed. Previous work has shown that mudflow behavior can be well represented by a Herschel-Bulkley model. In a laminar regime, generally ...

Abstract: A material exhibits thixotropic behavior if its apparent viscosity decreases under stress and if it recovers its initial viscosity when unloaded. This thixotropy is well defined for fluids, but it is not well understood ...

Abstract: To predict debris flow characteristics it is necessary to determine the rheological properties of these mixtures. It is suggested that such a mixture can be obtained by adding successively to clear water, coarser particles ...
