TXT-tool 2.386-2.1 A System to Forecast Rainfall-Induced Landslides in Slovenia

Abstract

Nowadays, an increasingly important area of work in landslides prediction is the development of tools to generate warnings to potentially affected communities. For the last 20 years many countries and cities have been affected by heavy rainfall leading to landslides and Slovenia is no exception. Therefore, public awareness of extreme events has notably increased across the world in different sectors. In order to provide a solution to the problem a national landslide warning system, Masprem, has been developed based on three main raster datasets: landslide-triggering rainfall threshold values, precipitation forecasts, and landslide susceptibility maps. At the moment, a landslide warning system predicts landslide probability for the area of Slovenia in the scale 1:250,000 twice a day. A Masprem system also calculates landslide predictions on a local level, including maps of exposure of inhabitants, buildings and different types of infrastructures to potential landslide occurrence at a scale of 1:25,000 for five selected municipalities. In the present Teaching Tool a design of the system for modelling a probability of landslide through time in Slovenia is highlighted.
