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.

Estimating hydraulic conductivity of internal drainage for layered soils in situ [PDF]

Hydrology and Earth System Sciences, 2013
The soil hydraulic conductivity (K function) of three layered soils cultivated at Paradys Experimental Farm, near Bloemfontein (South Africa), was determined from in situ drainage experiments and analytical models.

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.

Calibrating the wetting front pressure head of the Green and Ampt infiltration model

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Green–Ampt (GA) model is a classical analytical solution of the Richards equation used to predict soil water infiltration. Based on a modified form of Darcy's law, it assumes piston‐like flow with a constant pressure head at the soil surface and in the saturated zone, separated from the unsaturated region by a sharp wetting front.

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 ...

Investigation and quantification of hydraulic gradient and precipitation effect on flow and solute transport in the capillary fringe and saturated zone

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract Although the capillary fringe (CF) zone plays a critical role in water flow and solute transport within porous media, its influence is often neglected in numerical models. In this research, the HYDRUS‐2D model was validated with data from a physical experiment.

Evaluation of different formulations of the van Genuchten-Mualem hydraulic conductivity model [PDF]

, 2013
O fluxo de água na zona não saturada é regido pela interação entre as condições naturais na superfície e as propriedades hidráulicas do solo, sendo que dentre essas últimas a condutividade hidráulica tem grande importância.

Filter Paper Method for the Determination of the Soil Water Retention Curve

Revista Brasileira de Ciência do Solo, 2015
High cost and long time required to determine a retention curve by the conventional methods of the Richards Chamber and Haines Funnel limit its use; therefore, alternative methods to facilitate this routine are needed.

Spatial and vertical distribution of redox‐sensitive elements and their controlling factors in deep soils under contrasting land cover in the Gulf Coastal Plains

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract Redox processes in soil governs key biogeochemical cycles and influence carbon, nitrogen, and phosphorus dynamics. However, their role in deep vadose zone soils remains poorly understood, particularly in variably saturated environments with heterogeneous hydroclimatic, landscape position, and land use conditions.
