- Abstract
- Coarse sediment transport processes in steep headwater streams may vary between bedload and debris
flows events, depending on basin geomorphology and sediment supply. This paper compares two small
catchments (drainage area 4-5 km2) located in the Eastern Italian Alps where the dominant sediment
transport processes differ substantially, i.e., debris flows in the Moscardo Torrent and bedload events
in the Rio Cordon. The two basins were selected because they provided the unique opportunity to analyze
long-term data of debris flow and bedload volumes, respectively. The two basins are compared in terms
of peak discharge, event duration, and magnitude-frequency characteristics of transported sediment volumes.
Additional bedload data from two more Alpine experimental basins are also considered. The results
show that, for comparable recurrence intervals, debris flow volumes are 2-3 orders of magnitude larger
than bedload volumes. This contrasting sediment transfer activity can be attributed to different basin and
channel morphologies, which are analyzed in terms of sediment supply conditions, longitudinal profiles
and slope-area curves. (literal)
