Developing a simple artificial intelligence fuzzy-based model for estimating saturated hydraulic conductivity of soil [PDF]
Scientific ReportsSaturated hydraulic conductivity is one of the important physical properties of soil in modeling water and solute transport, irrigation management, and drainage issues. Laboratory and field methods for directly measuring this parameter are time-consuming

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.

A Comparison and Validation of Saturated Hydraulic Conductivity Models [PDF]
Water (Switzerland), 2020 Saturated hydraulic conductivity (Ksat) is fundamental to shallow groundwater processes. There is an ongoing need for observed and model validated Ksat values. A study was initiated in a representative catchment of the Chesapeake Bay Watershed in the Northeast USA, to collect observed Ksat and validate five Ksat pedotransfer functions.

Scaling the saturated hydraulic conductivity of an alfisol [PDF]
Journal of Soil Science, 1989 SUMMARY Alfisols exhibit a high degree of spatial variability in their physical properties. As a result, it is difficult to use information on physical parameters measured at one location to model larger‐scale hydrologic processes. In this study, the saturated hydraulic conductivity,
