Relationships among basin area, sediment transport mechanisms and wood storage in mountain basins of the Dolomites (Italian Alps)

摘要

The present work analyses the linkages between basin geology, shallow landslides, streambed morphology and debris flow occurrence in several small watersheds of the Dolomites (Italian Alps). Field survey and GIS analysis were carried out in order to seek correlations among basin area, basin geology, spatial frequency of landslides, in-channel wood storage, and local bed slope.
