Numerical modelling of vadose zone flow for a shallow groundwater wetland using HYDRUS-1D

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.

Modeling Heavy Metal Transport in Soil Using HYDRUS-1D Simulation

Natural and Engineering Sciences
The problem of heavy metal pollution in soil, particularly in industrial regions, has a greater impact on human environmental health and other agricultural practices. To devise effective remediation measures for these contaminants, the transportation behavior of the pollutants must be examined.

Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba

, 2019
In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool.

Efficiency of drip irrigation in amaranth production using the HYDRUS-1D model

Frontiers in Sustainable Food Systems
The negative impact of climate change is potentially damaging agroecosystem services that have constrained agricultural production and caused water scarcity in Central Asian countries, particularly in Uzbekistan. This study evaluates the efficiency of full (FDI) and deficit (DDI) drip irrigation regimes for amaranth (Amaranthus spp.
