Data on debris-flow volumes in northeastern Italy

This catalog presents data for 809 debris flows that occurred in 537 basins in mountainous areas of northeastern Italy between the mid-19th century and 2016. The region considered covers an area of approximately 22,000 km^2^. For each record, debris-flow volume, year of occurrence, drainage basin area, and the geographical coordinates of the basin outlet are reported. The sources of debris-flow volume data are classified into four classes: historical data from the literature and unpublished written sources; post-event surveys; debris-flow hydrographs measured in instrumented catchments; topographic measurements in sediment traps.
