dc.descriptionGeomorphologic and hydraulic methods were used to evaluate the reported magnitude of an extraordinary flood in west-central Arizona. The peak discharge of the Bronco Creek flood of August 19, 1971 was estimated by the U.S. Geological Survey (USGS) as 2080 m3/s (73,500 ft3/s) from a 50 km2 (20 mi2 ) basin. As such, it stands as one of the world's largest known rain fall generated floods to come from a basin of this size. It is likely that the USGS estimate is too high because of the application of the slope-area method in a high gradient alluvial channel with unstable boundaries.
