Field and laboratory estimates of pore size properties and hydraulic characteristics for subarctic organic soils

Abstract Characterizing active and water‐conducting porosity in organic soils in both saturated and unsaturated zones is required for models of water and solute transport. There is a limitation, largely due to lack of data, on the hydraulic properties of unsaturated organic soils in permafrost regions, and in particular, the relationship between hydraulic conductivity and pressure head. Additionally, there is uncertainty as to what fraction of …
