Study of the hydraulic properties of slate processing fines and fitting to Van Genuchten’s model

Boletín Geológico y Minero, 2009
Slate processing fines could be used as surface material for the revegetation of slate dumps and tailings, because their properties are compatible with plant growth. Yet, the study of their hydraulic properties (water holding capacity and permeability) is essential for knowledge of processes such as water movement and solute transport, water supply to ...

Determining the Threshold Value of Basil Yield Reduction and Evaluation of Water Uptake Models under Salinity Stress Condition

مجله آب و خاک, 2016
Introduction: Several mathematical models are being used for assessing the plant response to the salinity of the root zone. The salinity of the soil and water resources is a major challenge for agricultural sector in Iran.

Fracture–Matrix Flow Partitioning Governs Retention Regime Transitions in Unsaturated Fractured Rock

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Upscaling unsaturated flow in fractured rock remains challenging because fractures and matrix often exhibit sharply contrasting hydraulic behaviors across saturation states. Here, we demonstrate that unsaturated flow undergoes a transition between matrix‐ and fracture‐dominated regimes.

Comparison of Accuracy of van Genuchten and Brooks & Corey models for Simulating Water Flow in Forest Floor using HydroGeoSphere Code

مجله آب و خاک, 2017
Introduction: The forest residuals play an important role in runoff rate, soil erosion, and soil infiltration capacity of protecting mineral (surface) soils from the direct impact of raindrops.

Modelling Climate Change Effects on Groundwater Recharge and Temperature for a Pre‐Alpine Lysimeter

Hydrological Processes, Volume 40, Issue 7, July 2026.
Climate change is projected to increase winter groundwater recharge and extreme precipitation events in pre‐alpine regions. Groundwater temperatures will rise by up to 26%, primarily driven by air temperature. These trends pose challenges for future water availability and quality, requiring adaptive water resource management.

Improving the Reliability of Groundwater Recharge Estimates by Modelling Stable Water Isotope Transport in Soils

Hydrological Processes, Volume 40, Issue 7, July 2026.
Three 1‐D unsaturated zone models (HYDRUS‐1D with isotope fractionation) were calibrated with volumetric water content (θ) alone versus θ and δ18O δ2H from soil water. Adding isotopes constrains the parameter spaces and reproduces isotope profiles despite θ extremes, and reveals heterogeneous recharge in semi‐arid Tamil Nadu, South India.

Extension of the Gardner exponential equation to represent the hydraulic conductivity curve

Journal of Hydrology and Hydromechanics, 2019
The relative hydraulic conductivity curve Kr(h) = K/Ks is a key variable in soil modeling. This study proposes a model to represent Kr(h), the so-called Gardner dual (GD) model, which extends the classical Gardner exponential model to h values greater ...

Can one‐dimensional infiltration models reproduce soil moisture variations in landslide‐prone hillslopes? Evidence from Petrópolis, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The distribution of soil moisture, resulting from the movement of infiltrated water, plays a fundamental role in the hydrological dynamics of hillslopes and in the triggering of landslides. Although water flow in soils occurs in multiple directions due to combined vertical and lateral fluxes, one‐dimensional (1D) flow models are widely adopted

Estimation of van Genuchten Equation Parameters in Laboratory and through Inverse Modeling with Hydrus-1D

Journal of Agricultural Science, 2018
Soil water retention curve (SWRC) becomes important because it guides when and how much to irrigate, optimizing the use of water; can be obtained in the field or laboratory, being commonly determined in the laboratory with porous plate apparatus, and the determination is compromised by issues such as time and labor.
