“…The hydraulic parameters of soil were determined by the type of local soil, and the solute transport parameters were determined by the nature of solute. In the specific modeling process, the soil hydraulic parameters were predicted using the pedotransfer function ROSETTA based on the dry bulk density, sand content, silt content, and clay content of the soil (Dou et al 2022 ). Then, the specific values of each parameter can be determined through parameter sensitivity analysis, calibration, and validation process.…”

A series of complex physical and chemical processes, such as interception, migration, accumulation, and transformation, can occur when pollutants in stormwater runoff enter the growing media layer of bioretention facilities, affecting the purification of stormwater runoff by bioretention facilities. The migration and accumulation of pollutants in the growing media layer need long-term monitoring in traditional experimental studies. In this study, we established the Hydrus-1D model of water and solution transport for the bioretention facilities. By analyzing the variation of cumulative fluxes of NO 3 - -N and Pb with time and depth, we investigated pollutant migration and accumulation trends in the growing media layer of bioretention facilities. It can provide support for reducing runoff pollutants in bioretention facilities. The Hydrus-1D model was calibrated and verified with experimental data, and the input data (runoff pollutant concentration) for the pollutant concentration boundary was obtained from the SWMM model. The results demonstrated that the cumulative fluxes of NO 3 - -N and Pb increased with the passage of simulation time and depth of the growing media layer overall. From the top to the bottom of the growing media layer, the change rates of the peak cumulative fluxes of NO 3 - -N and Pb were strongly linked with their levels in the runoff. An increase in rainfall decreased the content of NO 3 - -N and Pb in the growing media layer, and this phenomenon was more obvious in the lower part of the layer. Graphical Abstract

“…Therefore, the soil desalination rate decreased from 57% above the subsurface pipe to 44% at the farthest point from the subsurface pipe. In the research of Dou et al, when 225 mm of winter irrigation quota was used, the soil desalination rate decreased from 56% directly above the subsurface pipe to 50% at 10 m from the subsurface pipe [57].…”

Subsurface pipe drainage (SPD) is an important technique for the improvement of saline–alkali lands in China. Winter irrigation after crop harvest is a key measure used in the Yellow River irrigation area in northwest China to reduce soil salinity in the root zone of crops. To optimize winter irrigation under SPD, the calibrated HYDRUS-2D model was utilized in this study to investigate the effects of soil texture (clay loam, silt loam, loam, and sandy loam), initial soil salinity (1, 3, 5 g/kg), and the winter irrigation quotas (80, 100, 120, 150, 180 mm) on the rate of soil desalination. In this study, soil salinity levels during the stable production of common crops such as sunflower and corn in the Yinbei Irrigation District in Ningxia, China, were taken as the thresholds, efficient utilization of irrigation water was considered, and suitable crops and appropriate winter irrigation quotas for different soil textures and levels of soil salinity were proposed. Soil with a salt content of 1~3 g/kg is suitable for the planting of corn with 80 mm of irrigation water. Sandy loam soil with a salt content of 3~5 g/kg is suitable for sunflower–corn intercropping with 120 mm of irrigation water. Sandy loam soil with a salt content exceeding 5 g/kg is suitable for the planting of sunflower with 80 mm of irrigation water. Other types of soils need to be improved by reducing the spacing between subsurface pipes, using desulfurized gypsum, biochar, and other additives. People engaged in agriculture can utilize this research to determine the appropriate volumes of irrigation water, crop types, planting systems, and subsurface pipe parameters based on local conditions.

“…The Hydrus model was mainly applied to agricultural irrigation [53], salt leaching [54], elemental transport [55], pollutant transport [56], and model coupling [57]. Ji Baoliang [58] applied Hydrus software to analyze and compare the movement of soil water under different soil conditions, and the simulated values fit well with the measured values; Zhang Hua et al [59] used the Hydrus numerical simulation method to simulate and validate the model for 3 g/L sea ice water irrigation, and the validation results showed that the model has good reliability; Gao Yue [60] used the Hydrus model to simulate He Kangkang [51] used the Hydrus-1D model to simulate the changes of water and salt fluxes within the soil over a long time series of 6 years, which provided theoretical guidance for the water saving potential and sustainability of brackish water use in the low plains of North China; Yu Yang [61] combined GMS Dou Xu [62] used the Hydrus-2D model to simulate soil water-salt dynamics in the 0-100 cm range, and used the measured soil water-salt content values in 2020 and 2021 to rate and validate the Hydrus-2D model. Tian Huiwen [63] used Hydrus-2D to develop a two-dimensional model of soil water, salt, and heat transport under drip irrigation and semi-membrane cover conditions, and considered kinetic sorption during salt transport.…”

The key to saline land management and improvement is to understand the soil water and salt transport laws and to carry out scientific regulation. In order to propose a scientific and reasonable model for soil salinity control, it is necessary to study the principle of water and salt transport in soil, the transport law with time and space, which is also the theoretical basis for understanding the occurrence and evolution of saline soils in the region and preventing secondary salinization of soil. In recent years, the study of water-salt transport and its simulation model has become one of the research hotspots in the field of agriculture, especially in the northwest of China. This paper systematically summarizes the research progress and applications of water-salt transport characteristics, models, influencing factors and the popular software Hydrus at home and abroad, and summarizes the advantages and disadvantages of the models and the influencing factors of water-salt transport, and introduces the research results of many scholars in the field of water-salt transport, and gives an outlook on the future research and development trend of water-salt transport.
