Traditional soil hydraulic models based on capillarity theory, poorly characterize soil structure (e.g., soil macropores) and adsorption forces, which limits their ability to accurately describe soil hydraulic properties under near-saturation and low soil water content conditions. Consequently, these models struggle to accurately simulate soil water movement.
In this study, we evaluated the performance of different soil hydraulic characteristic models using continuous field-measured soil moisture data from seven FLUXNET sites. We employed the FXW-M3 model, which accounts for soil structure, adsorption, and capillary forces, and the VGM model, which considers only capillary forces. Using the improved HYDRUS-1D software, we simulated and analyzed site-specific soil moisture data.
The results indicated that the FXW-M3 model significantly improved the accuracy of soil water movement simulation. The average root mean square error (
These results highlighted the significant impact of soil structure and adsorption forces on soil water movement.
