Fuzzy regression for electrical resistivity-hydraulic conductivity relationships

Fuzzy Kalman Filtering of Hydraulic Conductivity

This paper addresses the utilization of expert information in groundwater hydrology. Given that a fuzzy model of hydraulic conductivity can be provided by appropriate experts for some spatial domain, crisp measurements can be used to update the model using a fuzzy Kalman filter. The motivation behind this algorithm is to respect the relative integrity of each data source, while still taking adv...

Hydraulic conductivity measurment for subsurface drainage system

Sonic Representation of Reservoir Electrical and Hydraulic Conductivity Variations

Electrical and hydraulic conductivities in the reservoir environment can vary over many orders of magnitude over very small distances, while human vision is limited to perception of a Cartesian space in which the perceptual scales in all directions are commensurate. This means that visual plots of electrical or hydraulic conductivity variations with respect to a spatial coordinate must plot the...

Effective Unsaturated Hydraulic Conductivity

Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...
