METODA IDENTIFIKACE TEKTONIKY NA ZÁKLADĚ ZMĚNY ŠÍŘKY ÚDOLNÍHO DNA (NA PŘÍKLADU VSETÍNSKÉ BEČVY)
The paper deals with the identification of fault tectonics on the basis of topographic maps analysis. The investigated parameter is the valley floor width in the drainage basin of the Vsetinská Bečva River. In the first stage it is necessary to determine theoretic profile of the valley floor width downstream increment. For its construction has been used the magnitudo (Shreve 1966). In the next stage the deviations were calculated between theoretic and real profile of the valley floor width. These deviations were divided into groups according to their lithology and their orientation to prevailing direction of strata. The sections whose deviations were anomalous to average of groups are presumed to be affected by tectonics. This method is suitable as preliminary step for the following field investigation.
