Research on the Law of the Irrigation Water Infiltration in YaoBa Oasis Based on Hydrus-1D Model [PDF]
Earth Sciences, 2015 To study the law of irrigation water infiltration in soil is the basis of putting forward reasonable irrigation system. This paper takes YaoBa Oasis in Alxa Zuoqi,Inner Mongolia, China as the research object, based on field investigations and data collection, and chooses three test sites at the field to obtain the parameters of the model. The change of

Soil salt leaching under different irrigation regimes: HYDRUS-1D modelling and analysis [PDF]
Journal of Arid Land, 2013 Field irrigation experiments were conducted in the Hetao Irrigation District of Inner Mongolia, China, to study the effects of irrigation regimes on salt leaching in the soil profile. The data were used to calibrate and validate the HYDRUS-1D model. The results demonstrated that the model can accurately simulate the water and salt dynamics in the soil ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract Modeling unsaturated water transport in porous media traditionally relies on the Richards equation (RE) with hydraulic conductivity formulations to consider only capillary liquid water flow. However, this simplification neglects thin water films adsorbed onto particle surfaces, which can contribute significantly to flow under medium to dry ...

A Novel Approach to Characterize and Model Drywell Infiltration Capacity
Water Resources Research, Volume 62, Issue 8, August 2026.Abstract Drywells are vadose‐zone wells constructed for infiltration and recharge, typically positioned far above the water table. They provide for efficient infiltration, with high infiltration rates per land area, because the infiltration process is below the land surface.

Simulation of Soil Temperature Dynamics with Models Using Different Concepts
The Scientific World Journal, 2012 This paper presents two soil temperature models with empirical and mechanistic concepts. At the test site (calcaric arenosol), meteorological parameters as well as soil moisture content and temperature at 5 different depths were measured in an experiment
