Details of Rule of Thumb by Kuyumjian

Experienced BAER team members often use their own rule of thumb, which was developed based on their experience and post-fire monitoring/observation, and works well within certain regions. An experienced BAER hydrologist (pers. comm., Kuyumjian 2007) suggested using the following rule of thumb, which requires a minimal amount of input information.

Rule of Thumb

Q_p = 300 x A_sx I x 1.25

	where
	Q_p	=	peak flow in cfs;
	I	=	precipitation intensity in inch/hour;
	A_s	=	size of high burn severity area in mi²; and,
	1.25	=	bulking factor.
