APALI – Avalanche Probability Along Linear Infrastructure
Issler, Dieter (NGI-Rapport;20200431‐01‐TN, Research report, 2023-09-28)To secure linear infrastructure in the most cost-efficient manner, hazard hot-spots need to be known not only with regard to the intensity of possible events but also their probability. Traditional hazard mapping methods ... -

Comments on avalanche flow models based on the concept of random kinetic energy
Issler, Dieter; Jenkins, JT; McElwaine, J.N. (Peer reviewed; Journal article, 2017)In a series of papers, Bartelt and co-workers developed novel snow-avalanche models in which random kinetic energy RK (a.k.a. granular temperature) is a key concept. The earliest models were for a single, constant density ... -
