The purpose of this work was to determine the impact of anthropogenic activities, which consisted in the expansion of the national road 51 to change the water relations in the Upper Pas??ka catchment. Hydrological measurements were carried out on the Pas??ka River near the Gry?liny village. Studies have shown that the expansion of road 51 has changed the way the river basin has been developed. The area of agricultural and forested areas decreased in favor of paved and built-up areas, which resulted in an increase ...

Small rivers play an important role in the development of the hydrographic network and are tributaries of basin-forming rivers. Usually, it is shallow, which largely exposes them to the high impact of anthropogenic load. Anthropogenic pressure on water resources, especially in the Moscow and Moscow region, reached a rather significant level in this period. A critical situation occurs during the low water period, when the rivers switch to groundwater feeding and their runoff becomes minimal. With the formation of r...

The paper considers the state of the vegetation cover of the high-mountain valley of Kok Jailau, which is located in the central part of the Ile (Zailiyskiy) Alatau Ridge (Northern Tien Shan). The results of the study showed a different degree of anthropogenic transformation of the vegetation cover. It is noted that in the natural (background) state the vegetation cover was preserved only in hard-to-reach areas, mainly in the upper part of the mountains (on steep slopes of the Kumbel Ridge, river valleys, etc.).
