Assessing salinity leaching efficiency in three soils by the HYDRUS-1D and -2D simulations [PDF]

, 2019
Salinity leaching is necessary to sustain agricultural production in irrigated croplands. Improving salinity leaching efficiency not only conserves water but also reduces groundwater contamination. Current leaching requirement (LR) calculations are based

Dataset for: Physics-informed neural networks with monotonicity constraints for Richardson-Richards equation: Estimation of constitutive relationships and soil water flux density from volumetric water content measurements by Toshiyuki Bandai and Teamrat A. Ghezzehei

, 2022
Simulation of soil moisture dynamics is important for various fields, such as agriculture, hydrological modeling, and natural disasters. Such simulations are conducted by solving a partial differential equation (PDE) called the Richardson-Richards ...

Modeling Nitrogen and Phosphorus Transport in Vadose Zone using HYDRUS- 1D

Rona Teknik Pertanian, 2021
Abstract. The application of large manure on the agricultural lands that derived from the Concentrated Animal Feeding Operations (CAFOs) could cause excess nutrients such as nitrogen and phosphorus transport to the groundwater through vadose (unsaturated) zone.

Assessment of the Physically-Based Hydrus-1D Model for Simulating the Water Fluxes of a Mediterranean Cropping System [PDF]

Water, 2019
In a context characterized by a scarcity of water resources and a need for agriculture to cope the increase of food demand, it is of fundamental importance to increase the water use efficiency of cropping systems. This objective can be meet using several currently available software packages simulating water movements in the “soil–plant–atmosphere ...

Using Hydrus-1D software to predict cumulative infiltration values for different soil textures

Siberian Journal of Life Sciences and Agriculture
Four soil samples with varying textures (clay loam, clay, sandy clay loam, and silty loam) were collected from different locations in Nineveh Governorate, northern Iraq. Four different models were used to calculate air-entry values, including Lenhard (Ψe)
