Geoinformation mapping of transport in the Baikal region

The article presents the results of researching changes in the stream discharge in the forest-steppe zone in the XXI century in the conditions of the environmental regime. Due to the lack of data on the stream discharge within the researched area in previous years, the length of the channel network is considered as an indicator of water content – an indicator that generally correlates with the value of the length of the channel network. Elementary watercourses are taken as the object of research, since in short periods they are able to show high variability under the influence of external conditions, especially if it is necessary to establish the influence of specific local factors. The research was conducted on the territory of the “Sengileevskie Mountains” National Park, which lies within the Volga landscape region and the Low Volga region in the forest-steppe zone. This territory exists in the conditions of the nature protection regime and has a high forest cover. The research was based on the materials of the expedition work carried out in the summer of 2022. and the results of geoinformation analysis of topographic maps reflecting the position of the sources of elementary watercourses in 2001. As a result of the expedition work, the length of the channels of elementary watercourses as of 2022 has been established, the indicator of the change in the length of their channels in the XXI century – from 2001 to 2022 has been calculated. The fact of the multidirectional dynamics of the length of the channel network of elementary watercourses is established. In the conditions of the nature protection regime established at the beginning of the XXI century, against the background of the restoration of the landscapes of the researched territory, there is an increase in the length of the channel network of elementary watercourses, which has a correlation with the areal indicators of the restoration of natural plant communities – forests and meadows.

The article presents the results of researching the dynamics of the length of the channel network of elementary watercourses in the north of the forest-steppe zone in the XXI century. The research was conducted on the territory of the catchment basin of the Ketarsha River of the Privolzhskaya Upland, characterized by a high degree of anthropogenic transformation. The research is based on the materials of the expedition work, carried out in the summer of 2023, the results of geoinformation analysis of remote sensing data, topographic maps and literary sources. The fact of reducing the length of the channel network of elementary watercourses in 2023 compared to 2001 has been established. During the expedition work in 2023, the current position of the sources of elementary watercourses was established, based on comparison with the data of topographic maps of 2001, the direction of the change in the length of their channels was established and its quantitative indicators in the XXI century were calculated. In the conditions of actively plowed landscapes on the researched territory, there is a reduction in the length of the channel network of elementary watercourses.

The article presents the results of research the dynamics of the length of the channel network of elementary watercourses within the territory of the catchment area of the Birlya river in the XXI century. The researched area is located in a zone of broad-leaved forests and characterized by high anthropogenic pressure on the landscape (high plowing and relatively high population density). The research is based on the materials of expedition work, carried out in the summer of 2020 and on geoinformation analysis of topographic map data. As a result of field work, the current position of the sources of elementary watercourses was realized, and the change in the length of rivers was calculated by comparing the position of it’s sources in 2001, recorded on topographic maps, with the position of the sources of rivers in 2020. Established the fact of multidirectional dynamics of the length of the channel network of elementary rivers in comparison with 2001 and the significant role of local conditions that determine this dynamics: the nature of agriculture, forest cover, ploughing, and the influence of animals.
