Abstract
The mineral and granulometric composition and some physical and physicochemical parameters of soils identified during laboratory studies allowed us to reveal the peculiarities of soils of the Chukotka mudflows. The influence of these peculiarities on the formation of a mudflow suspension, which is a transporting mudflow substance, is estimated. The structural–rheological model of movement for the reviewed territory implies the formation of mostly cohesionless mudflows, the main water part of which is free. The laboratory studies, however, showed the presence of a significant amount of finely dispersed aggregated particles in the mudflow matrix, which saturate the water flow with a clay suspension in case of flooding, which allows us to classify these flows as cohesive. The cohesion of the mudflow mass during the movement is acquired due to the decomposition of aggregates leading to a change in physical characteristics of the mudflow.
