Long-term monitoring of bedload and debris flows in two small catchments of the Eastern Italian Alps.

In this paper, results from experimental stations located in two streams of the Eastern Italian Alps are presented: the Rio Cordon (5.0 km2) and the Moscardo Torrent (4.1 km2). The former hosts a measuring station for water and sediment (both suspended and bedload) transport rates operating since 1986, whereas the latter was set up in 1989 to monitor debris-flow events. Differences in sediment dynamics between the two basins are quantitatively investigated by using a magnitude-frequency analysis that highlights the relatively low sediment supply of the Rio Cordon and the unlimited sediment availability in the Moscardo Torrent.
