Conditions for landslides in fine-grained soil
The map viewer "Conditions for landslides in fine-grained soil" is intended to be used at an early planning stage to identify areas where there may be a risk of landslides and where further investigations need to be carried out. In order to interpret the information correctly, basic geotechnical and geological skills are required.
The information is based on a calculation algorithm (Tryggvason, 2014) which defines land with fine-grained soil types which is vulnerable to landslides on the basis of soil type (according to SGU’s product soil types 1:25 000-1:100 000), terrain model (national elevation model of the Swedish Mapping, Cadastral and Land Registration Authority) and critical slope (1:10). In addition to the areas of caution, the areas of coverage (with scale ranges) are also displayed in front of the soil-type information on which the analysis was based.
The corresponding data set can be ordered through SGU customer services.
