hydrosférou

Hydrosférou is a neologism used in some French-language discussions to designate a holistic framework for the Earth's hydrosphere and its interactions within the Earth system. The term blends the concept of the hydrosphere with an emphasis on couplings and processes that connect water bodies across air, land, and biota. It is not universally adopted and lacks a formal standard definition, but is used to frame interdisciplinary studies of water in environmental and climate contexts.

Scope: It covers the distribution and movement of freshwater and seawater, properties of water bodies, and the physical processes of the water cycle, including evaporation, precipitation, infiltration, runoff, river discharge, ocean circulation, and cryospheric exchanges. It also encompasses socio-hydrological aspects such as water use, governance, and human impacts on hydrological systems.

Methodology: Researchers employing hydrosférou concepts often use a combination of in situ observations, remote sensing, hydrological modeling, and coupled Earth system models to analyze interactions among the hydrosphere, atmosphere, lithosphere, and biosphere.

Applications and relevance: The framework is used to study climate change impacts on water resources, flood and drought risk assessment, freshwater security, ecosystem health, and adaptation planning. It emphasizes cross-cutting links between natural processes and human systems.
