ABSTRACT

For landslides studies associated with some projects, rigorous landslide hazard and risk assessments are often not carried out because they are not warranted, or because of lack of time. Such projects include relatively small projects, preliminary studies, and/or emergency response. The same is often the case with respect to such projects and rigorous slope stability assessments. For such projects, experienced professionals often use the concepts associated with rigorous slope stability analysis to guide their thought process and judgement when carrying out qualitative slope stability assessments. In the same way, this writer suggests that for such projects, professionals should use the concepts associated with rigorous landslide hazard and risk assessments to guide their thought process and judgement when carrying out qualitative landslide hazard and risk assessments. In many cases, the thought process contributes more to professional judgement than the details.
