Abstract: The Level 1 Stability Analysis (LISA) computer program is a tool to help estimate the relative stability of natural slopes or landforms. LISA results areintended to support management decision at the multi-project or resouce allocation level of planning. The primary use of the probability of failure estimated using LISA to make qualitative, relative comparisons between the stability of landforms, and to identify areas that should be targeted for additional analysis. LISA also can be used to estimate the relative decrease in stability of landform after timber harvet due to a potential reduction in estimated tree root strength and an increase in groundwater levels. The probability of failure also can be used quantitatively in a risk analysis, such as an expected monetary value (EMV) decision analysis.
