To reach this ambitious goal, it is elementary to understand the behaviour and characteristics of sediment transport. The knowledge about this complex natural process is still limited, therefore field observations and data on sediment transport are needed. Work package 5 (WP5), with the title “Sediment transport monitoring”, basically aims on providing this data to expand the understanding of sediment transport, debris flows and wood transport. Throughout the whole Alpine Region, a lot of different monitoring methods in sediment transport are currently in use. The presented first SedAlp Milestone, with the title “Protocol for data collection method in sediment transport”, aims on ensuring the comparability of the collected monitoring data. Therefore, three standard protocols on bedload transport, debris flow and wood transport monitoring have been developed. These proto...

Field data necessary to test transport models and better understand sediment transport phenomena result scarce and difficult to obtain. In the present study, we focus the attention on the results obtained by multiple field surveys carried out after the November 2012 event when bedload transport along the Rio Cordon, a small step-pool channel in the eastern Italian Alps, was generated. The stream is characterized by the presence of a station, managed by the Regional Land Safety Department of ARPAV (Regional Agency for Environmental Protection and Prevention of Veneto), for monitoring water and sediment fluxes since 1986. The measuring station consists of an inclined frame that separates fine from coarse sediments (D>20 mm), which are continuously assessed by a series of ultrasonic sensors fitted above a storage area. After the November 2012 event, a series of field surveys were carried out to identify the source area of the mobilized sediment. The quantification of bedload and fine loads using a Terrestrial Laser Scanner device was then performed, allowing the definition of the volume and grain-size characteristics of the transported sediment. The results have shown that the main source area was represented by lateral small debris flow located just upstream the measuring station. Thanks to the grain-size characterization and the field recognition it was possible to confirm that no morphological changes of the main channel have occurred upstream the sediment sources immission. Therefore, the input of sediment for the stream derives only from lateral debris flow process located near to the catchment output.
