ARTICLE ANNOTATION

quote
This article resents modeling of avalanche impact in the Kamchik Pass area using the RAMMS::LSHIM (Large-Scale Hazard Indication Modelling) tool for avalanche scenarios with a 30-year return period. The approach is based on numerical simulations employing the high-resolution AW3D Global DEM and morphometric criteria for identifying potential avalanche release zones. The results made it possible to produce a large-scale map of calculated impact pressure distribution and to identify the most hazardous sections along the Kamchik highway. Modeling confirmed the efficiency of the RAMMS::LSHIM approach for analyzing spatial patterns of avalanche impact and detecting potentially hazardous areas. The maps could also be calculated for more extreme avalanche cycles with return periods of 100 and 300 years. The results can be used for estimating avalanche loads on engineering structures and for substantiating protective measures.
