hüdroloogilise

Hüdroloogiline is an Estonian adjective meaning related to hydrology, the science that studies water in the Earth system. Hydrology covers the occurrence, distribution, movement, and properties of water, including precipitation, evaporation, and transpiration, surface water in rivers and lakes, groundwater, as well as snow and ice. It also concerns the storage and fluxes of water in soils and the atmosphere. The term is used to describe phenomena, measurements, and analyses that involve water in natural and built environments.

In practice, the term appears in phrases such as hüdroloogilised uuringud (hydrological studies), hüdroloogilised andmed (hydrological data), and hüdroloogiliste mudelite (hydrological models). It may also modify references to processes or risks, for example hüdroloogilise protsessi (the hydrological process) or hüdroloogilise riskide hindamine (assessment of hydrological risks). Hydrological terminology is foundational for understanding water balance, flood and drought dynamics, and groundwater/surface-water interactions.

The field intersects with meteorology, geology, environmental science, civil engineering, and water resources management. Applications include water-resource planning, flood defense design, irrigation and drainage planning, urban water management, and environmental monitoring. The adjectival form hüdroloogiline or its inflected variants is commonly used in academic, technical, and policy contexts to specify aspects related to the study and management of water within the landscape.
