The occurrence of damaging landslides along transportation corridors in the mountainous western United States can be expected to rise with the expansion of the regional transportation network. Because national forests typically encompass major mountain ranges throughout the West, assessing landslide hazard is of special concern to forest management. The Fishlake National Forest in central Utah employs quantitative methods to assess this hazard. The matrix-assessment approach forecasts landslide hazard for planning purposes. It seeks to avoid reactivation of existing landslides or creation of new ones. The other method is applied to maintenance concerns. It emphasizes the frequency and areal extent of landsliding over time. Both methods have the following common characteristics: (a) each employs a numerical procedure, (b) each employs measurable terrain characteristics, and (c) procedure results can be assigned to specific geographic locations. The matrix assessment for transportation corridor planning is illustrated by application to the Wasatch Plateau section of the Fishlake National Forest. The method used in maintenance problems is illustrated by application to an 8.2-mile section of UT-153 along Beaver Canyon in the Tushar Mountains. (Author)
