New tool for avalanche forecasting in the Krkonoše Mountains

Original language description

The Krkonoše Mts., with the highest peak reaching 1602 m a.s.l., is the highest mountain range in the Czech Republic. Despite its low altitude they experience considerably high avalanche activity, even causing fatalities. Unfortunately, and so far, the local authorities do not have available a professional tool for avalanche forecasting. A new project, which started in 2013, focuses on the crea- tion of a mathematical model based on statistical analysis of historical data, weather forecast and de- tailed terrain analysis. Because the project is at the beginning, therefore this contribution describes only methods to be employed and data available. The study area is 454 km 2 and includes 53 permanent avalanche paths, which are very well s urveyed and documented. The avalanche paths have been scanned by LiDAR to get very accurate slope and terrain characteristics. In addition a landuse survey is being carried out to obtain information about possible avalanche triggering zones and terrain roughness. Weather and snow condition data covering more than 1100 avalanche events in the last 50 years are being analysed for fitting and calibrating statistical models. Historical data on avalanche types and movement will be compared with terrain surveys and simulations using physical models like RAMMS, Flow-R, AVAL-1D and SAMOS. These data sets will be used for the development of a new avalanche forecasting model, which will be well suited to be employed as a public avalanche alert system for the Krkonoše Mts. and consequently will be extended to other mountain ranges in the Czech Republic.
