摘要：	The purpose of this report is to discuss protocol for the removal of debris on roadways, maintaining worker safety, recording of key information for future use, and selecting feasible mitigation measures to protect the roadway from debris-flow hazards. Collection of data during removal of debris from roadways will provide a database that may assist in ranking and/or mitigating roadways with frequent debris-flow hazards. A debris flow, sometimes referred to as a mudslide, is a flowing mixture ranging from watery mud to thick, rocky mud that can carry large items such as boulders, trees, and other debris. Debris flows travel rapidly down slope along drainage channels or stream valleys, often transporting and depositing a large volume of material in areas where the gradient flattens, such as roadways. Because of their relatively high density and viscosity, debris flows can move, and even carry away, vehicles and other objects as large as bridges and railroad cars. / Supplementary Notes: Sponsored by Colorado Dept. of Transportation, Denver.
