Abstract:
Debris flows and debris floods are rapid moving mass flows, consisting of water and solids. In alpine areas, these relocation processes represent a threat to the population and the infrastructure. In order to assess debris flows, informations about their properties and flow behavior is required. The flow velocity of debris flows is commonly back-calculated from past events. The forced-vortex equation is often used to estimate the velocity of debris flows. It is based on the radii of curvature and morphometric parameters. In this research the superelevation of selected events is analyzed. The relations between topographical and event-related data are investigated. Chronicles of natural hazards and own data collection are the base of this research. My results indicate that morphometric parameters such as sinuosity and melton-number have limited influences on superelevation. It turns out, that the ratio of radius of curvature and channel width (R/B-factor) has a significant impact on superelevations. In subscription to the events of the present work it considers to debris floods with a bed slope of 12 - 22% and for debris flows between 24 - 50% with a R/B- factor between 6 and 30. The superelevations are between 2,1 and 4,8 m.
