Evaluation and application of the modified van Genuchten function for unsaturated porous media

Journal of Hydrology, 2019
Proper soil hydraulic functions of the water retention curve (the WRC) and relative hydraulic conductivity (the RHC) are essential for studies of unsaturated groundwater flow in soils. Various mathematical expressions of these functions have been proposed, including the widely used van Genuchten-Mualem model combining the van Genuchten formula for the ...

Improved Prediction of Unsaturated Hydraulic Conductivity with the Mualem‐van Genuchten Model

Soil Science Society of America Journal, 2000
In many vadose zone hydrological studies, it is imperative that the soil's unsaturated hydraulic conductivity is known. Frequently, the Mualem–van Genuchten model (MVG) is used for this purpose because it allows prediction of unsaturated hydraulic conductivity from water retention parameters.

Estimation of van Genuchten-Mualem Parameters from Spectral Induced Polarization Measurements

Proceedings, 2013
The application of spectral induced polarization (SIP) surveys to estimate hydrological properties of the subsurface is promising. For the interpretation of the SIP data, the knowledge of the relationships between soil hydraulic properties and parameters obtained from SIP measurements is essential.

Bereitstellung von van‐Genuchten‐Parametern zur Charakterisierung der hydraulischen Bodeneigenschaften

Zeitschrift für Pflanzenernährung und Bodenkunde, 1993
AbstractDie Wasserspannungs‐/Wasserleitfähigkeitsbeziehung eines betrachteten Bodenvolumens läßt sich mit Hilfe der van‐Genuchten‐Gleichung näherungsweise auch dann abschätzen, wenn die hierfür notwendigen Parameter aus der Wasserspannungskurve abgeleitet werden.
