This work proposes the study of the sedimentary processes compared with the sedimentary record of the Moscardo Torrent alluvial fan, located in the Eastern Italian Alps. This comparison allows us to better analyze and understand the role that such debris flow events have in building up the fan and reshaping its surface. Given the high frequency of debris flow events (from one to four per year) the Moscardo fan is a very good place where to study fan processes. This basin has been monitored since 1989 yielding a long sequence of events stage data and related rainfall. Facies analysis and sedimentological investigation of the fan deposits have been carried out within this work in order to determine sediment distribution and define the main sedimentary processes responsible for the sediment transport and deposition on the fan. Utilizing the long series of recorded stage data, different hydrographs features have also been analyzed and compared with related sedimentary processes.

Abstract
This work proposes the study of the sedimentary processes compared with the sedimentary record of the Moscardo Torrent alluvial fan, located in the Eastern Italian Alps. This comparison allows us to better analyze and understand the role that such debris flow events have in building up the fan and reshaping its surface. Given the high frequency of debris flow events (from one to four per year) the Moscardo fan is a very good place where to study fan processes. This basin has been monitored since 1989 yielding a long sequence of events stage data and related rainfall. Facies analysis and sedimentological investigation of the fan deposits have been carried out within this work in order to determine sediment distribution and define the main sedimentary processes responsible for the sediment transport and deposition on the fan. Utilizing the long series of recorded stage data, different hydrographs features have also been analyzed and compared with related sedimentary processes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
