Hi All,

I calibrated my model for streamflow and sediment at various outlets and wanted to see if my phosphorus value were ready for calibration but the model model overpredicts the TP and/or SRP values compared to actual observed values at the outlet.

Why is this happening? When I run SWAT-Check I see this:

Sediment and Flow are properly calibrated and match observed values.
