Impacts of spatial-temporal rainfall structures and antecedent wetness on flood variability at the catchment scale

Key Points

• Flood variability is significantly influenced by both spatial-temporal rainfall structures and antecedent wetness.
• The most impactful factors were identified, indicating notable variability in 75% of monitored catchments.
• Observational analysis across various catchments demonstrated complex interactions between rainfall and soil moisture.
• This work supports improved flood management strategies, though further investigation of regional differences is needed.
