Thicker terminal roots had higher hydraulic conductivity (Ks) than finer roots, but Ks declined from roots to terminal branches in most species. Additionally, branch and leaf Ks increase with tree size, indicating greater hydraulic efficiency in larger canopy species....Below-ground, we presented evidence that an increase in SRL is linked to decreased hydraulic conductivity and is influenced by root diameter....Above-ground, branch and leaf hydraulic conductivity tend to be higher in species with higher wood density, which are also more prevalent in upper canopy layers.

The results showed that the SVR method had excellent accuracy in identifying the hydraulic conductivity and specific head boundary. The MLP method had good accuracy in identifying the release intensity of the pollutant sources....Therefore, by combining SVR and MLP (SVR-MLP), SVR was used to construct an inverse mapping relationship identifying hydraulic conductivity coefficients and head-specific boundary values, and MLP was used to identify pollutant release intensities, thus having the synergistic identification of all three

Free swell index, gas permeability, hydraulic conductivity tests and microscopic tests were conducted to evaluate the gas /hydraulic performance of GCL....When hydrated and permeated with salt solution, the hydraulic conductivity decreased from 2.6× 10-10 to 3.8 × 10-11 m/s as XG dosage increased from 0 to 2%....The findings demonstrated that XG dosage no less than 1.0% could maintain low gas permeability and acceptable hydraulic conductivity of XG-GCL when exposed to salt solution.
