Impacts of storm events on watershed phosphorus critical source area identification based on SWAT model

Puntos clave

• Storm events significantly influence phosphorus distribution in watersheds, altering critical source area locations.
• Findings indicate changes in phosphorus levels during storm events, with variances noted in 30% of analyzed watersheds.
• Modeling utilizing the SWAT framework effectively identifies shifts in critical source areas due to storm events.
• The results underscore the necessity for adaptive watershed management to address phosphorus runoff during storms.
