Research of slope deformations in the České Středohoří Mts. (Dolní Zálezly - Dubický Hill slope deformation)
Abstract
This contribution presents first recent results of research of the slope deformation Dolní Zálezly – Dubický Hill. The site is located on the left bank of the morphologically distinct Labe/Elbe river valley between cities Lovosice and Ústí nad Labem.
The locality is built by Tertiary neovolcanites of the České Středohoří Complex. The main goal of the ongoing research is to evaluate detailed mapping and geodetic monitoring of the slope deformation, which is potentially danger of important transport communications and buildings.
The slope deformation was developed by combination of block rock fall and landslide activity in the last century. Potentially danger represents especially huge rock blocks in unconsolidated scree accumulation in the middle part of the slope.
In this part were found the cracks with ice caves too. Selected morphometric characteristics as hypsometry or slope gradients were derived from DEM based on terrestrial laser scanning and trigonometric measurements.
