Abstract
The article is devoted to the analysis of modern methodological approaches to assessing anthropogenic pressure on watercourses, with a focus on the vulnerability of small river ecosystems to various forms of technogenic impact. Indicator, index, balance–mass, bioindication, geoinformation, and modeling approaches applied in the practice of hydroecological monitoring are considered. Their advantages, limitations, and possibilities for adaptation to regional conditions are described. Special attention is given to the integration of data of different nature (physico-chemical, biological, spatial) within the framework of comprehensive assessments. The expediency of applying combined methods for assessing the state of small rivers in the Almaty region under conditions of climatic variability and increasing anthropogenic pressure is substantiated.
It is additionally shown that the use of a systemic approach makes it possible to identify not only the current state of water bodies but also the trends of their changes under the influence of economic activities. Such analysis provides a scientific basis for predicting potential risks of ecosystem degradation and for developing preventive measures. A comprehensive assessment of anthropogenic impact on small rivers is an important tool for improving ecological monitoring, developing environmental protection measures, and justifying strategies for rational water use. The obtained conclusions can serve as a basis for the formation of sustainable strategies for water use and the protection of small watercourses, as well as for the development of regional and national adaptation programs under conditions of climate change.
