“…In recent years, significant efforts have been made to develop methods for forest fire danger monitoring, prediction and assessment, for example, in the Baikal basin [66][67][68]. Currently, a project is being implemented to develop methods for monitoring forest fire dangers caused by transport infrastructure, namely, railways.…”

Pyrolysis (thermal decomposition) is considered as the most important stage of a forest fire before direct forest fuel ignition. This process is accompanied by soot particle formation. Such particles have a negative impact on public health in the vicinity of forest fires. The purpose of this article was to investigate the heat and mass transfer process occurring in a typical forest fuel element (birch leaf). The pyrolysis and soot formation processes were taken into account, and various forest fire scenarios were considered. Computational experiments were carried out using the high-level programming language Delphi. Heat and mass transfer processes were described by nonlinear non-stationary differential heat conduction equations with corresponding initial and boundary conditions. The differential equations were solved by the finite difference method. Nonlinearity was resolved using a simple iteration. The main results of the research were (1) physical and mathematical models proposed for modeling forest fuel pyrolysis, taking into account soot formation and conditions corresponding to various forest fires; (2) a computer program coded in the high-level programming language Delphi; (3) the obtained temperature distributions over leaf thickness; (4) volume fractions obtained for various components dependent on time and space coordinates. The qualitative analysis of the dependencies showed that the temperature distributions in the birch leaf structure are similar for all forest fire types and differ only in absolute value. The intensity of the soot formation process directly depends on the forest fire type. The presented results should be useful in predicting and assessing forest fire danger, including near the facilities of the Russian Railways.

“…For definiteness, the article considers the following types of forest fires: low and high intensity surface forest fires, crown forest fires and firestorms [23]- [26]. Meteorological characteristics correspond to the parameters on the territory of the Republic of Buryatia (Russian Federation) [27], [28]. Thus, the goal of the study can be formulated.…”

Forest fires have a negative impact on the functioning of the railway. The aim of the work is a mathematical modeling of heat transfer in the structures of a passenger carriage under the influence of radiation from a forest fire front. The originality of the study is explained by modeling heat transfer in structural materials of a passenger carriage under the influence of radiation from a forest fire front. Low and high intensity surface forest fires, crown forest fires are considered. Most of the previously published works are devoted to the analysis of the causes of forest fires, including the ones near the railway. The software implementation of the mathematical model is performed in the RAD Studio software in the high-level programming language Delphi. Mathematically, heat transfer in the materials of a passenger carriage is described by nonstationary differential heat conduction equations with corresponding initial and boundary conditions. In order to solve the partial differential equations, the finite-difference method and the locally one-dimensional method are used. Difference analogs of differential equations are solved by the marching method. The main findings of the study are: 1) physical and mathematical models of heat transfer in the structures of a passenger carriage under conditions of exposure to radiation from a forest fire; 2) the obtained temperature distributions in the inhomogeneous structure of the passenger carriage wall; 3) simulation has shown that a low-intensity surface forest fire causes a relatively safe forest fire impact scenario, while a high-intensity surface forest fire impact is a potentially dangerous scenario; 4) the scenario of the impact of a crown forest fire is unambiguously dangerous at any parameters; 5) the results obtained in this paper and the expected in future investigations will create a physical basis for the development of software for fire safety systems for rolling stock on the railway. The presented results are proposed to be used for forecasting, monitoring, and assessing forest fire dangers during the operation of the rolling stock of JSC Russian Railways.

“…For example, in the article [11] authors discusses the differences of meteorological factors influence on forest fires occurrence in two climatically contrasted forestries of the Republic of Buryatia. In the other work [12] five meteorological fire risk indices are calculated for 13 German states between 1993 and 2010.…”

Forest fires in Volga federal district of the Russian Federation (2000-2020 years)

Using statistical data, the dynamics of forest fires in the Volga federal district of the Russian Federation from 2000 to 2020 years is analyzed. The number and area of forest fires were considered as the initial data. At the same time, the total area of forest fire and of burned forests were taken into account separately. It was found that during the period under review, the minimum number of fires was recorded in 2000, and the maximum in 2018. Out of 14 subjects included in the Volga federal district, forest fires in the Republic of Bashkortostan were studied in detail. The dependence of the number of fires by season is established. Using correlation analysis of the statistical data for 2000-2020, the fact of strong dependence between the number of fires in the Volga federal district and forest area covered by fire was established.
