Zusammenfassung |
Sediment transport in mountain rivers and torrents is a substantial process
within the assessment of flood related hazard potential and vulnerability in
alpine catchments. Focusing on fluvial transport processes, river bed
erosion and deposition considerably affects the extent of inundation. The
present work deals with scenario-specific bed-load transport modelling in a
large alpine valley in the Austrian Alps. A routing scheme founding on
empirical equations for the calculation of transport capacities, incipient
motion conditions and drag forces is set up and applied to the case study
area for two historic flood events. The required hydraulic data result from
a distributed hydrological-1-D-hydraulic model. Hydraulics and bed-load
transport are simulated sequentially providing a technically well-founded
and feasible methodology for the estimation of bed-load transport rates
during flood events. |
