Soil Water and Salt Dynamics in a Coastal Saline Cotton Field, Nanpi County, China

5.5 KB of simulation results from a study on coastal saline soils in Nanpi County, Hebei Province, China. The dataset, authored by Feng Li and last updated in May 2026, contains results from HYDRUS-1D model simulations calibrated with field data to quantify changes in soil water storage and salt accumulation under different groundwater depth scenarios over a ten-year period.

Use Cases

• Modeling soil water storage changes based on groundwater depth scenarios described in the study
• Analyzing salt accumulation patterns in the vadose zone based on simulated salinity data
• Calibrating hydrological transport models for saline environments using the provided field and simulation data
• Assessing agricultural sustainability risks based on the relationship between groundwater levels and topsoil salinization

Strengths

• Model was calibrated with field data, achieving RMSE values below 0.05 for soil moisture and below 0.3 for soil salinity
• Simulations cover a ten-year period and quantify specific impacts, such as a 45–47 cm increase in water storage when groundwater level was raised
• Dataset is openly shared under a CC-BY-4.0 license

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The 5.5 KB size indicates a very limited scope, likely containing summary or aggregated results rather than raw time-series data
