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