Hydrus Simulation Results for Soil Water and Salt Dynamics in Coastal Saline Soils

1.5 MB of original HYDRUS-1D simulation results investigating groundwater depth effects on coastal saline soils in Nanpi County, China. The dataset, authored by Feng Li and shared under a CC-BY-4.0 license, contains model outputs from a ten-year simulation period. Results include quantified changes in soil water storage and salt accumulation under three groundwater scenarios.

Use Cases

• Calibrating and validating soil water transport models based on the described HYDRUS-1D simulation framework.
• Analyzing the relationship between groundwater depth and topsoil salinization based on the quantified salinity changes.
• Studying long-term water and salt redistribution in coastal saline environments based on the ten-year simulation results.
• Supporting agricultural water management decisions based on the findings regarding safe groundwater thresholds.

Strengths

• Model was calibrated with field data, achieving RMSE below 0.05 for soil moisture and below 0.3 for salinity.
• Simulation covers a ten-year period, providing a long-term perspective on water and salt dynamics.
• Results include specific quantified impacts, such as a 45–47 cm increase in water storage and a doubling of surface salinity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain modeling tasks.
• Data is geographically specific to a coastal saline area in Nanpi County, Hebei Province, China.
