Аннотация: The theoretical description of the temperature field in the soils during freezing or thawing is carried out using solutions of Stefan’s problem. A mathematical model based on the equations of thermal conductivity for frozen and thawed layers. We consider the areas in which there are lakes or bogs. We distinguished the following layers in the vertical structure of the zone of permafrost: thawed soil, frozen soil, water, ice, snow. We offer a simplified numerical algorithm for solving of one-dimensional (in the vertical direction) heat conduction problems with moving boundaries of phase transition with the formation of new and cancellation of existing layers. A simplified numerical algorithm for solving one-dimensional (in the vertical direction) heat conduction problems with moving boundaries of phase transition with the formation of new and cancellation of existing layers is offering. © Siberian Federal University.

Аннотация: Simple description of the temperature field in soils during their freezing or thawing is considered with the help of solutions of Stefan problems. A mathematical model is based on the equations of thermal conductivity for the frozen and thawed layers. In the vertical structure of the permafrost zone, three layers are distinguished: thawed soil, frozen soil, snow. A simplified numerical algorithm for solving one-dimensional (in the vertical direction) thermal conductivity problems with moving phase transition boundaries with the formation of new and cancellation of existing layers is proposed. © Published under licence by IOP Publishing Ltd.

   Перевод заглавия: A Model of the Dynamics of the Frozen Soil Depth in Bog-Lake Landscapes
Аннотация: Теоретическое описание температурного поля в почвах при их промерзании или оттаивании осуществляется с помощью решений задач Стефана. Математическая модель основывается на уравнениях теплопроводности для мерзлых и талых слоев. Рассматриваются территории, на которых имеются озера или болота. Выделяются следующие слои в вертикальной структуре зоны вечной мерзлоты: талый грунт, мерзлый грунт, вода, лед, снег. Предлагается упрощенный численный алгоритм решения одномерных (в вертикальном направлении) задач теплопроводности с подвижными границами фазового перехода с образованием новых и аннулированием существующих слоев.
The theoretical description of temperature fields in soils during freezing or thawing is carried out using solutions of Stefan's problem. We developed a mathematical model based on the equations of thermal conductivity for frozen and thawed layers. Those areas in which are lakes or bogs were considered. We distinguished between following layers in the vertical structure of the zone of permafrost: thawed soil, frozen soil, water, ice, snow. We offer a simplified numerical algorithm for solving of onedimensional (in the vertical direction) heat conduction problems with moving boundaries of phase transition with the formation of new and cancellation of existing layers.

Аннотация: In this paper the new family of the stream routing curves was obtained on the basis of disparity in the "water stage vs water volume" curve on the rise and the recession of the flood wave. The paper contains the results of the numerical experiments with the different stream routing curves using the row data about the artificial outflows downstream from Novotveretskaya and Ivankovo dams. © 2019 Published under licence by IOP Publishing Ltd.

Аннотация: The northern territories of Eastern Siberia are characterized by a permafrost-taiga structure of the surface layer of soil, which reduces the efficiency of geological exploration using seismic sources of explosive and vibratory types. Therefore, Geotech Holding Company developed a special eco-friendly electromagnetic pulse source "Yenisei", which seismic waves are the subject of analysis using high-performance computing in this paper. Computational technology, worked out previously for solving the problems of the dynamics of viscoelastic, elastic-plastic, granular and porous media, is applied to the analysis of wave motion of a soil near a point of perturbations. It is shown that the main frequency of generated strain waves substantially depends on the elastic characteristics of a soil in the near-surface zone. A comparison of the results of computations obtained in the framework of the model of static loading with instant unloading and the model taking into account the monotone loading stage with subsequent pressure relief showed the validity of the hypothesis about the presence of added mass of a soil under the loading platform. This mass accumulates impact energy and emits seismic waves due to oscillatory motion. © 2019, Peter the Great St. Petersburg Polytechnic University.
