title: PHYSICOCHEMICAL INDICATORS OF WATER AND SOIL IN NATURAL WATER BODIES

description: Physicochemical indicators of water and soil play a crucial role in assessing the environmental quality of natural water bodies. These parameters reflect the ecological condition, pollution level, and sustainability of aquatic ecosystems. This study examines the key physical and chemical characteristics of water and bottom sediments (soil) in natural reservoirs, including temperature, pH, dissolved oxygen, turbidity, mineral content, and nutrient concentration. The findings highlight the importance of integrated monitoring of both water and sediment parameters to evaluate ecosystem health and prevent environmental degradation. Understanding these indicators is essential for environmental protection, water resource management, and sustainable development.
