dc.description.abstract | NGI has conducted research on avalanches and related processes since 1973. This report gives a short insight in the work done in 2019. While experiments with artificial release of avalanches in the Ryggfonn experimental site were not possible, data was collected on natural avalanche events, both at Ryggfonn and other naturally released avalanches. Work has been done on the statistical approach on avalanche release and runout probability. The feasibility of Voellmy-based numerical models was tested against observed data and simple block models. A three-dimensional CFD model was tested to study the usefulness of detailed physically based wind fields in complex terrain for avalanche mapping and forecasting purposes. The work was presented at several meetings, papers and NGI technical notes which will be made accessible at the project webpage. Taking the results and open questions as well as external input from collaborators and stakeholders into account, the project description for 2020–2022 was elaborated for a successful continuation of the avalanche research. | en_US |
