“…The main data for calculating the anthropogenic pressure were: the vector layer of the river basins of the Volga Federal District, including 68,787 basins with an average area about 15 km 2 [24]; OpenStreetMap data (OSM) [25]; topographic maps of Russia on a scale of 1:1,000,000 and 1:500,000; and a raster layer of cropland, obtained from the interpretation of time-series of MODIS vegetation indices [26].…”

The analysis of the geoecological state of basin geosystems was carried out by evaluation of the anthropogenic pressure on the basin. As indicators that directly or indirectly reflect the anthropogenic impact, the following were used: population density in the basin, density of the road network, and agricultural development of the basin territory. The spatial and statistical distributions of indicators were analyzed after the indicators were brought to a unified scale (transformation, normalization). The integral indicator of anthropogenic pressure, calculated as a linear combination of individual variables, was ranked to six categories of anthropogenic pressure: “absent”, “very low”, “low”, “moderate”, “high”, and “very high”. Using the developed methodology and prepared geodata, for the first time at scale of 1:200,000, the territory of the Volga Federal District was zoned according to the anthropogenic pressure on each river basin. Basins with a high and very high pressure are concentrated around large cities. Most of the basins belonging to the categories of low and moderate anthropogenic pressure are located in the forest-steppe and steppe zones with maximal agricultural development. Basins with zero and very low pressure lie in the north of the study area, in the forest zone, and in the southern Ural.

This study was aimed to reveal relationships between the formation of the structures of river systems and to discover the tectonic structural features of the territory. We analyzed the morphometric parameters of river catchment areas of various orders, which comprise the Kama river basin. A digital terrain model in ESRI ArcGis 10.4 geoinformation system was used. Within the identified river basin geosystems, quantitative morphometric characteristics of the terrain were calculated for comparative analysis. Multidimensional statistical analysis methods were used to group the basins with respect to their sets of geometric and morphometric characteristics. A spatial typification technique was developed to distinguish the basin geosystems by their morphometric indicators. This study pioneered in using the results of cluster analysis for identification of seven groups of basins, which reflect the spatial heterogeneity of the ancient tectonic elements and the geomorphological conditions within the entire territory of the Kama river basin. It is established that the types of the river basin geosystems with characteristic morphometric features are related to various ancient tectonic structures, which suggests a genetic relationship of endogenous processes of river channel fracturing and the diversity of geometric parameters of different river basins.

The article presents the methodology of environmental assessment of the state of a river basin based on the landscape approach using geoinformation systems. This study implements the landscape approach to evaluation, when types of terrain, i.e. the natural geographical systems, act as the spatial-operational units, which ensures the objectivity of the obtained results. The main land use categories are used as the factor of anthropogenic pressures. With this purpose, a spatial database of the functional use of the studied territory, based on the results of a satellite image analysis, was created.
