Web1 sep. 2001 · Plants used for measuring osmotic water flow were also employed to measure hydraulic conductivity of root systems in the presence of hydrostatic pressure gradients. During these measurements, roots were enclosed into a steel chamber to apply pneumatic pressure to the root medium (Fig. 1A ). WebThe analytical solution for average hydraulic conductivity perpendicular to fracture plane heterogeneities is slightly different than the layered aquifer solution. Results show that perpendicular flow through heterogeneous fractures is more sensitive to heterogeneity than in layered aquifers.
