porevattnet
Porevattnet refers to the water that fills the void spaces between soil grains, sediment particles, or rock pores. In fully saturated conditions the pore water is the principal phase carrying dissolved substances, and its composition can differ markedly from the water outside the pore spaces. In unsaturated soils, pore water coexists with air and is held by capillary forces, slowly changing as evaporation and infiltration occur.
In soils and sediments, porevattnet is central to nutrient availability, microbial metabolism, and geochemical weathering. Its
Sampling and analysis: Pore water is collected using methods such as rhizon samplers, diffusion samplers (peepers),
Applications: Porevattnet data are used in groundwater and environmental risk assessments, studies of nutrient cycling in
