vol. 313(Relevance of the Topic: Ukraine belongs to water-deficient states (according to the World Water Assessment Programme (WWAP) classification), hence the issue of protecting the natural hydrological network as the basis for preserving the country's water resources is relevant. Special concern arises regarding the preservation of natural hydroecosystems in the Steppe zone, which have been subjected to the influence of intensive anthropogenic and climatic disruptions for a long time. Particularly problematic in this regard is the steppe Mykolaiv region, where local water resources are extremely limited and water supply is mainly provided by water inflows from other regions. In terms of specific indicators of water resource availability (per unit area and per capita), the region ranks among the lowest in Ukraine [1]. With the increasing severity of climate instability, the key issue in the theoretical and applied hydroecology of the region is the possibility of the existence of natural watercourses and their hydrosystems. Most of them belong to the category of "small rivers" and are characterized by extremely high sensitivity to environmental conditions. The functioning of small rivers and their biocenoses is insufficiently studied; until now, they have been practically outside the scope of systematic scientific research. The main information data characterizing the surface water bodies of the Mykolaiv region belong to large and medium rivers - the Southern Bug, Synyukha, Inhul, and Inhulets, while recent publications on the ecology of small rivers in the Lower Southern Bug region are almost absent. Even in review and reporting publications of state institutions and organizations in the region [2], information on small rivers is scarce, and the exact number of them is unknown. Also lacking are publications on the ecological state of water bodies, river valleys, and watersheds of small watercourses and their role in modern agrolandscapes. The situation with environmental assessments of the drainage network of the southwestern slope of 19 the Ukrainian Crystalline Shield - the hydrogeological zone of fractured waters, which includes territories of 5 districts of the Mykolaiv region, is especially complex. All these areas are characterized by extremely unfavorable water supply conditions, and their population lacks access to quality drinking water, except for imported water. Thus, the actual relevance of hydroecological research on small rivers and their limited informational specificity have largely contributed to the selection of the dissertation topic, focusing predominantly on applied issues of ecology and water management significance of steppe hydrosystems. Accordingly, the relevance of the hydrological study and ecological assessment of small rivers in the Lower Southern Bug region, understanding the structural-functional organization of their hydrosystems, and searching for rational ways to protect natural water bodies collectively determined the choice of the topic, definition of the purpose, and tasks of the scientific research. In practical terms, the relevance of the work is determined by the insufficient study of basic issues of the modern ecohydrological structure and water management prospects of small intermittent rivers, the direct study of which was carried out in the territory of the Mykolaiv region - the most water- deficient and drought-prone region of continental Ukraine. ), 2024
