Estimating Ecological Status of Kalaus River in the Stavropolskii Region, Russia

The purpose of the study is to assess the impact of water resources use and modern global challenges on the ecological state of the Klaus River and the justification of water protection measures. The Kalausis the river in the Stavropolskii region of Russia being an important source of water. Water usage has resulted in water loss, depletion, and deterioration. As a result, water shortages completely outweigh the natural river flow. The water is categorised as "very dirty" in terms of quality. Diffuse runoff from agricultural lands is the main cause of river water contamination. In this research, estimates are provided for both the environmental river flow and the effectiveness of water protection measures. It considers the impact of lands on the flow volume and quality of river water, as well as the impact of global climate change on water scarcity. To raise the river's ecological status to "satisfactory," it is necessary to conserve the volume of environmentally friendly flow without reducing it. To improve water quality to "moderately polluted," integrated water protection measures are required.
