Short Summary

This study identifies rapid infiltration signatures from a global database using a dual-mechanism modeling framework, finding that rapid infiltration occurs in 26.6% of valid curves and its odds decrease with increasing absolute latitude, highlighting the importance of measurement context for hydrological modeling.

Objective

• To identify and characterize rapid infiltration signatures from a global database of infiltration measurements using a dual-mechanism modeling framework.

Study Configuration

• Spatial Scale: Global (analysis across 83 sites, 4,992 infiltration curves).
• Temporal Scale: Not explicitly defined, but based on infiltration measurements which are typically short-term events.

Methodology and Data

• Models used: Dual-mechanism modeling framework.
• Data sources: Global database of infiltration measurements.

Main Results

• Rapid infiltration signatures were identified in 26.6% of 4,992 valid infiltration curves.
• The occurrence of rapid infiltration varied among different measurement methods.
• Rapid and non-rapid infiltration signatures frequently coexisted within closely matched local contexts; 74.7% of qualifying groups at identical recorded locations contained both types of signatures.
• For rapid-classified curves, the fitted rapid component accounted for a median of 41.2% of cumulative infiltration.
• Across 83 sites, the odds of observing a rapid infiltration signature decreased by approximately 26% for every 10° increase in absolute latitude.

Contributions

• Provides a large-scale observational basis for understanding and investigating rapid infiltration.
• Highlights the importance of measurement context and independent physical evidence for improving the representation of rapid infiltration in hydrological and Earth system models.
