Modeling atrazine transport in soil columns with HYDRUS-1D
Water Science and Engineering, 2011 Both physical and chemical processes affect the fate and transport of herbicides. It is useful to simulate these processes with computer programs to predict solute movement.

Validation of Hydrus 1D Model in Selected Catchment of Slovakia [PDF]
Acta Horticulturae et Regiotecturae, 2017 Abstract Soil water content is very important for agricultural practice. Direct measurements of the soil moisture are being replaced by mathematical simulations and models step by step. One of the most used models for the simulation of the soil moisture is HYDRUS 1D model. This paper deals with HYDRUS 1D validity check in the Nitra River

Analysis of 2,4-D residues in soil profile using HYDRUS-1D model [PDF]
Iran Agricultural Research, 2018 Despite the benefits of herbicides, their persistence in soil can harm other plants in next rotations and contaminate ground water. The main purpose of this research is to simulate 2,4-dichlorophenoxyaceticacid(2,4-D) movement in silty clay loam soil ...

HYDRUS-1D Simulation of Nitrogen Dynamics in Rainfed Sweet Corn Production [PDF]
Applied Sciences, 2020 Nitrogen loss from agricultural fields results in contamination of ground and surface water resources due to leaching and runoff, respectively. Nitrogen transport dynamics vary significantly among agricultural fields of different climates, especially in ...

Numerical modelling of vadose zone flow for a shallow groundwater wetland using HYDRUS-1D
Modeling Earth Systems and EnvironmentAbstract This study employs HYDRUS-1D for modelling the vadose zone processes in a shallow groundwater wetland. HYDRUS-1D is based on Richards equation whose numerical solution heavily relies on reliable data derived from soil water retention curves. This modelling was supported by extensive field and laboratory measurements.
