Optimization of saturated hydraulic conductivity estimation using kriging in drainage networks

Applied Water Science, 2023
Statistical analysis of saturated hydraulic conductivity is the fundamental of engineering plans for water resource projects. In the other words, project solutions and designs depend directly on the accuracy of these statistical analyses and the methods ...

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Measurement of Hydraulic Conductivity in Oil Sand Tailings Slurries [PDF]

, 1996
: Fine tails, the resulting fine waste from oil sand processing, undergoes large-strain consolidation in tailings ponds. Its consolidation behavior must be analyzed using a large-strain consolidation theory, which requires the determination of the ...

Analytical expressions for macrodispersion in three-dimensional Sub-Gaussian hydraulic conductivity fields [PDF]

, 2021
Subsurface flow and transport settings are typically characterized by spatial variability of the underlying hydro-geological attributes (e.g., permeability and porosity) and a high degree of uncertainty associated with data and model parameter estimates.

Unsaturated Hydraulic Conductivity in Composite Porous Media [PDF]

, 2022
Determining the constitutive properties that describe the incipient hydraulic behavior of the materials, including the matrix domains and the distribution of macro and micropores, is crucial to analyzing the preferential water flow in saturated soils, ks,
