kokonaisvedensiirtokykyyn

Kokonaisvedensiirtokykyyn, often translated as total water transfer capacity or total hydraulic conductivity, is a concept used in hydrology and soil science to describe the ability of a soil or geological formation to transmit water. It is a measure of how easily water can move through a porous medium. This property is crucial for understanding groundwater flow, soil moisture dynamics, and the movement of contaminants in the subsurface.

The kokonaisvedensiirtokykyyn is influenced by several factors, primarily the size and interconnectedness of the pores within the material. Larger, well-connected pores allow for faster and greater water movement compared to fine, tortuous pores. The composition of the soil or rock, including the presence of clay, silt, sand, and gravel, significantly impacts pore structure. For instance, sandy soils generally have higher kokonaisvedensiirtokykyyn than clayey soils.

Furthermore, the degree of saturation also plays a role. A fully saturated material will exhibit its maximum water transfer capacity. Partially saturated conditions involve air occupying some pore space, which obstructs water flow and reduces the effective kokonaisvedensiirtokykyyn. This property is typically measured in units of length per time (e.g., meters per day). It is a fundamental parameter used in various hydrological models and assessments of water resources and environmental risks.
