Abstract:The Hydrus model, developed by the U.S. Salinity Laboratory, is mainly designed to simulate the transport of water, solutes and heat in the vadose zone, and currently, it has been used widely all over the world. In this paper, we systematically analyzed the progresses of Hydrus model researches in China based on screening 347 literatures from the CNKI and Web of Science databases, and these papers were published by Chinese scholars from 2017 to 2020. The results showed that Hydrus could well simulate the transport and transformation processes of water and solutes in different media. However, current application of Hydrus in China has been mostly limited to the one-dimensional simulation of small areas or indoor soil columns. In addition, the processes of calibrating the hydraulic and solute transport parameters needed to be further standardized and improved, while some studies lacked the systematic evaluation of Hydrus simulation results. It was suggested that future research on Hydrus models in China should be strengthened in two aspects:Firstly, Hydrus could be coupled with different environmental domain models to achieve the simulation of the whole process at a large scale such as cross a river basin; Secondly, the standard modules of Hydrus could be extended to add new functions to meet the real-world research needs.
