Description

Numerous debris flows occurred in the Huachuca Mountains of southeastern Arizona during the summer rainy season of 1988 in areas that were burned by a forest fire earlier in the summer. Debris flows occurred following a major forest fire in 1977 as well, suggesting a causative link between fires and debris flows. Abundant evidence of older debris flows preserved along channels and in mountain front fans indicates that debris flows have occurred repeatedly during the Holocene in this environment. Debris flow recurrence intervals for individual drainage basins in the study area are probably in the range of 500 to 1000 years, based on soil development in sequences of debris flow deposits.
