Using landslide susceptibility and hazard maps for road structures planning within landslide prone areas
Abstract
A problematic section of the E50 road passing through the ridge of the Chřiby Highlands and its surrounding were used as the study area. To determine the landslide hazard, quantitative methods of logistic regression analyse was used. The most important input parameters for evaluation of slope stability are the lithological structure, slope angle, elevation (DEM - digital elevation model), land use and distance from the watercourse. The area of interest also included the neighbourhood of E50, where a motorway was previously planned, but cancelled due to the risk of slope instability. The problematic sections of the planned motorway crossing the Chřiby Highlands were revised and two new variants of the motorway route were proposed on the base of achieved results.
