Vedenkulkuun

Vedenkulkuun is a Finnish term used in hydrology, soil science and plant physiology to describe the movement of water through a system, or more broadly the processes of water transport. The illative form vedenkulkuun appears in phrases such as vedenkulkuun liittyvät prosessit, indicating water-transport processes within a context or pathway.

The concept encompasses several pathways by which water can move. In soils, water transport includes infiltration, percolation, capillary rise and, at larger scales, groundwater flow. In living organisms, water moves from roots through the plant body to the leaves via xylem, driven by osmotic uptake, capillary forces and cohesion-tension mechanisms. In the atmosphere, water is moved by evaporation, transpiration and atmospheric circulation, completing the broader hydrological cycle. Measurements relevant to vedenkulkuun include hydraulic conductivity, water potential and matric potential, which help quantify how readily water moves under given conditions.

Applications of the concept span hydrological modeling, irrigation planning, drought assessment, ecosystem and climate studies, and soil-plant-water interactions. While vedenkulkuun is often used as an umbrella term for water-transport processes rather than a single definable variable, it serves to organize discussion around how water moves through soils, organisms and the atmosphere, and how these movements affect moisture availability and energy balance in a system.
