Accuracy of Different Methods in Determination of the Van Genuchten,s Retention Curve Coefficients [PDF]

مهندسی منابع آب, 2015
Soil water retention curve is an indicator of one of the most important soil hydrological properties that have high applications in various soil water issues, and it is widely estimated by the van Genuchten,s model.

The Effect of Drying around Power Cables on the Vadose Zone Temperature

Vadose Zone Journal, 2018
The effects of moisture migration away from power cables depend strongly in most soils on whether the soil has reached the so-called critical conditions (e.g., critical temperature) for a dry-out.

Simulation of Agricultural Wetland Area of Typology C through The Van Genuchten Model Approach

, 2017
Abstract.The use of groundwater flow equations in porous media is often applied optionally, i.e. under saturated soil or only for unsaturated conditions. Tidal agricultural zone of typology C, is an example of how these two assumptions can occur simultaneously.

Evaluation of Hydraulic Parameters Obtained by Different Measurement Methods for Heterogeneous Gravel Soil

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Knowledge of soil hydraulic parameters for the van Genuchten function is important to characterize soil water movement for watershed management. Accurate and rapid prediction of soil water flow in heterogeneous gravel soil has become a hot topic in ...

The response of hydraulic conductivity to air-trapped saturation in a dissolution process of trapped-air in quasi-saturated fine sands media

Shuiwen dizhi gongcheng dizhi
The hydraulic conductivity of a quasi-saturated aquifer decreases with the increase of air-trapped saturation, but it is difficult to obtain a continuous data on air-trapped saturation through the traditional displacement experiments due to limitations ...

Estimation of Van Genuchten Parameters using Ensemble Kalman Filter for Hydrological Modeling

, 2023
Nedbørsinduserte jordskred er en betydelig fare i Norge på grunn av bratte skråninger, mye nedbør, temperaturendringer og snøsmelting. Klimaendringer øker risikoen ytterligere. Prosjektet KlimaDigital, startet av SINTEF i 2018, har hatt som mål å utvikle et varslingssystem for nedbørsinduserte jordskred ved hjelp av sensorer.

Modified van Genuchten models for describing the entire soil water retention curve

Abstract This study presents a modified van Genuchten model that replaces the residual water content parameter (θR) with shift soil water content (∆θ) to fully characterize the soil water retention curve (SWRC). Derived from this, we introduce both two-segment and three-segment models.
