摘要：
The results of laboratory experiments on the distribution of impurity released by melting an ice plate placed in the coastal slope of a riverbed model in a hydraulic flume, as well as the determination of the filtration coefficient of wet sand with ice inclusions are presented in this paper. The obtained data were used to validate and verify the mathematical model of impurity propagation in deformable riverbeds of the permafrost zone. On the basis of the results of numerical and laboratory experiments, new dependencies of the propagation speed and impurity concentration on external thermal parameters, channel morphometry, and channel-forming soil characteristics were obtained. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
