What does hydrologically mean?
“Hydrologically” is an adverb meaning in relation to hydrology, the scientific study of water in the environment. It is especially used to describe the movement, distribution, storage, and cycling of water, and it often appears in discussions of rivers, groundwater, rainfall, drainage, watersheds, and climate change. For example, two regions may be described as hydrologically connected if water flows between them or if changes in one region can affect the other. The adverb is also useful when discussing a phenomenon from a water-management or water-cycle perspective. It is primarily a formal and technical term, though it can be understood in general contexts where the relationship between physical geography and water is important. Its related noun is “hydrology,” its adjective is “hydrological,” and its specialist-agent noun is “hydrologist.”

Where does hydrologically come from?
The word is formed from “hydrology,” which comes from Greek hydōr, meaning “water,” combined with the Greek-derived suffix -logia, meaning “study of” or “science of.” The related forms “hydrologist,” “hydrological,” and “hydrographic” share this water-related origin. English borrowed the family during the development of modern scientific vocabulary, and the adverb “hydrologically” was formed by adding the standard adverbial suffix -ly to “hydrological.”
