Effect of entrapped air on hydraulic conductivity in quasi-saturated porous media
Shui kexue jinzhan, 2019 The groundwater flow with entrapped air was termed as quasi-saturated flow. The entrapped air in quasi-saturated flow of aquifer had a significant influence on hydraulic conductivity of porous media.

Saturated Hydraulic Conductivity of Scandinavian Tills
Hydrology Research, 1990 There is a distinctive difference in hydraulic properties between the upper horizons of Scandinavian till soil and the deeper C-horizon. The hydraulic conductivity has been studied in different soil profile types, mainly Podzolic variants. In the topsoil there are correlations from grain size and porosity to hydraulic conductivity.

A pH‐Based Pedotransfer Function for Scaling Saturated Hydraulic Conductivity Reduction: Improved Estimation of Hydraulic Dynamics in HYDRUS [PDF]
, 2019 Hydraulic conductivity is a key soil property governing agricultural production and is thus an important parameter in hydrologic modeling. The pH scaling factor for saturated hydraulic conductivity (Ks) reduction in the HYDRUS model was reviewed and ...

Determining the Porosity and Saturated Hydraulic Conductivity of Binary Mixtures [PDF]
, 2009 Gravels and coarse sands make up significant portions of some environmentally important sediments, while the hydraulic properties of the sediments are typically obtained in the laboratory using only the fine fraction (e.g.,

Test of the Rosetta Pedotransfer Function for Saturated Hydraulic Conductivity
Open Journal of Soil Science, 2012 Simulation models are tools that can be used to explore, for example, effects of cultural practices on soil erosion and irrigation on crop yield. However, often these models require many soil related input data of which the saturated hydraulic conductivity (Ks) is one of the most important ones.

Controls on Saturated Hydraulic Conductivity in a Degrading Permafrost Peatland Complex [PDF]
Water Resources Research, 2023 AbstractPermafrost peatlands are vulnerable to rapid structural changes under climatic warming, including vertical collapse. Peatland water budgets, and therefore peat hydraulic properties, are important determinants of vegetation and carbon fluxes. Measurements of hydraulic properties exist for only a limited number of permafrost peatland locations ...
