Assessment of slope stability conditionsin the Rožnovská Bečva River basin, Vidče village
Abstract
Conditions and factors affecting slope failures development in the model area of the village Vidče in the Rožnovská Bečva River basin are analyzed based on field investigation of the slope failures within the scope of former Vsetín District. Old and recent landslides affect almost entire area of the studied region. Large sliding activity occurred during extreme precipitations and floods in the July 1997. The area under study is situated on the tectonic contact between Silesian and Rača Nappe Units of the Outer Flysch belt. The region is mostly build by rocks highly susceptible to denudation. The largest area covered by active and temporarily non-active landslides is found on the slopes of the Bečva River valley, which are subject to its lateral erosion. Smaller active as well as temporarily non-active landslide lies on the south slopes of the Maretka Stream valley, where the village Vidče is located. Numerous buildings are damaged or threatened by future landslide movements.
