Calibration of snow avalanche mathematical models using the data of real avalanches in the Ile (Zailiyskiy) Alatau Range

Abstract: SummaryThe calibration of the dry friction and turbulent friction coefficients is necessary for computer simulation of avalanches. The method of back calculation based on data on actual avalanches is used for this purpose. The article presents the results of the calibration of the Eglit's and RAMMS models for Ile Alatau range conditions. The range is located in Kazakhstan. The data on six avalanches in the same avalanche site were used. Five avalanches were dry, and one avalanche was wet. For wet avalanches of… Show more

“…Thus, the values of ξ varied from 100 m 2 /s to 500 m 2 /s. Similar low values of ξ have been obtained in simulations of avalanches in Ile (Zailiyskiy) Alatau range (Tian-Shan Mountains) [19,38,39].…”

“…Development, generalization and use of mass-point or block models for avalanches continue to this day (see, e.g., [19]). After calibration, these models can provide approximate estimates for the velocity and run-out distance of avalanches.…”
