Short Summary

This study used one-dimensional modeling to evaluate water-table response time, displacement, recession time, and total recharge under various extreme precipitation events across twelve soil textures, revealing that recharge is primarily governed by event magnitude and soil properties, rather than event duration.

Objective

• To evaluate the effects of extreme precipitation events (EPEs) on water-table dynamics (response time, displacement, recession time, and total recharge) across varying soil textures.

Study Configuration

• Spatial Scale: One-dimensional (vertical column)
• Temporal Scale: Extreme precipitation event durations of 1 day, 7 days, and 20 days. Water-table response times up to 200 days. Recession times up to 3.0 years.

Methodology and Data

• Models used: One-dimensional hydrological model
• Data sources: Simulated extreme precipitation events (0.20 m, 0.40 m, 0.60 m amounts); twelve varying soil textures.

Main Results

• Coarse soils (sand) respond to extreme precipitation events within days, whereas fine soils (clay) may take over 200 days.
• Water-table displacement ranged from 0.30 m to 1.64 m and increased with the magnitude of the extreme precipitation event.
• The time for water tables to recede ranged from 1.2 years to 3.0 years.
• Total possible recharge, estimated from porosity and displacement, ranged from 17% (clay) to 97% (sand), with an average of approximately 63% across all soil textures.
• Recharge is primarily governed by the magnitude of the extreme precipitation event and soil properties, not by the event's duration.

Contributions

• Provides new insight into how soil texture modulates groundwater response to extreme precipitation.
• Quantifies water-table response time, displacement, recession time, and total recharge across a wide range of soil textures under varying extreme precipitation event magnitudes and durations.
• Informs future water budget and resilience assessments.
