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.

Toward a structured workflow to harmonize soil water content products: A comparative study across different methods

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract This study introduces a structured, multi‐step workflow for harmonizing diverse soil water content (SWC) datasets to improve their meaningful comparability while preserving their intrinsic characteristics. The workflow addresses four components: unit, temporal, vertical, and lateral spatial harmonization, and is applied to point‐scale (PS ...

The effect of long-term irrigation with municipal treated wastewater on the saturated hydraulic conductivity of a silt loam soil and its estimation- a case study

علوم آب و خاک, 2017
Treated wastewater may influence soil structure, porosity and as a consequence, soil saturated hydraulic conductivity. This study aims to assess the effect of wastewater on saturated hydraulic conductivity; and to determine the suitable soil solids ...

Do data from the RISMA soil monitoring network support agricultural modeling requirements?

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract The Real‐Time In‐Situ Soil Monitoring for Agriculture (RISMA) network provides soil water and agri‐environmental data for conceptualization, calibration, and validation of remote sensing and modeling products for Canadian agriculture at 32 stations in seven watersheds in Saskatchewan, Manitoba, and Ontario.

Assessing the Relative Roles of Soil Water Potential and Atmospheric Demand on Vegetation Water Stress in Semi‐arid Ecosystems

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Understanding vegetation's response to soil water availability and atmospheric demand is critical for assessing the impact of drought and climate change on semi‐arid ecosystems. However, limited field‐based research has been conducted to assess the relative importance of these drivers on vegetation productivity.

The role of the water regime in a reclaimed limestone quarry

Journal of Forest Science
This study focused on the hydrophysical characteristics of an abandoned limestone quarry in Czechia. Six sites were examined; two sites were undergoing natural succession (the Quarry Wall and Reed Canary Grass plots, which had undeveloped arboreal layers)

Natural Vegetation Dynamics Confound the Impact of Ecological Restoration on Dryland Hydrology

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Large‐scale ecological restoration (ER) projects have increased shrub and grass cover and growth in arid and semi‐arid regions, but concurrently reduced terrestrial water storage (TWS) through enhanced evapotranspiration (ET). However, the impact of ER on TWS remains unclear due to the confounding effect of natural vegetation dynamics (driven ...

Using of pedotransfer functions for assessment of hydrolimits

Plant, Soil and Environment, 2002
Soil hydrologic coefficients, also called hydrolimits, are soil water contents defined for certain values of water potentials. Closer attention is paid to three hydrolimits: field capacity, point of decreased availability, and wilting point.

Determination of a pedotransfer function for specific air–water interfacial area in sandy soils: A pore network‐informed multigene genetic programming approach

Vadose Zone Journal
Understanding specific air–water interfacial area (SAWIA) is essential for characterizing and modeling various phenomena in vadose zone hydrology, such as virus and colloid transport, contaminant dissolution, evaporation, and the hydro‐mechanical ...
