The stability of slopes is a well-known subject introduced for more than a century ago, with pioneering work by e.g. Petterson (1916) and Hultin (1916). This led to development of well established calculation methods and the current national guidelines, in which the effect of climate is most often included as a variation of the (ground) water level. However, climate research show that the Nordic countries will suffer from increased average temperature, more precipitation and higher likelihood of intense precipitation. This is changing the environmental loads on slopes, in addition to secondary effects such as drought, fire and extreme cycles of drying-wetting and freeze-thaw. These new climate loads, combined with the uncertainties of both climate impact and soil properties, may lead to unnecessary, costly mitigation measures or undetected risks for infrastructure and constructions. The report compares four available methods for stability analyses, and discusses a new methodology for evaluating the stability of slopes, as an initial step for evaluating the effect of different climate scenarios on slopes stability. The report also presents climate scenarios which are likely to occur in relation to Swedish slopes and summarises international research on how these climate scenarios could affect the stability or the strength of the soil in the slope.
