Short summary
A well-constrained rainfall-runoff model forced by radar-derived precipitation is used to define rainfall intensity-duration (ID) thresholds for flash floods. The rainfall ID doubles in 5 years after a severe wildfire in a watershed in southern California, USA. Rainfall ID performs stably well for intense pulses of rainfall over durations of 30-60 minutes that cover at least 15%-25% of the watershed. This finding could help issuing flash flood warnings based on radar-derived precipitation.
