I. THE PROBLEMS
DEBRIS FLOWS
Another equally dangerous problem, usually in hillside or mountainous areas is debris flows. Remember that debris flows:
CONSIST of large quantities of soil, rocks, boulders, trees, or brush being moved by flood waters.
OCCUR when flood waters flow over hillside and natural streambed areas and are most serious in areas denuded by recent fire or grading.
ARE highly destructive and leave large quantities of sediment and rocks in their paths when the storm subsides.
CONTAIN sufficient strength to destroy objects in their path.
CAN be controlled or directed to reduce property damage (Fig. 2).
