The deposits, stratigraphy, and surface morphology of debris-flow fans are a record of past debris-flow activity, and as such can provide useful information about debris-flow hazards. The morphology of the fan surfaces reflects both characteristic debris-flow inundation patterns and the frequency of channel avulsions; surface morphology is a sensitive indicator of the type of debris-flow hazard. A conceptual model describing the linkages between dispositional processes and surface form on debris-flow fans, developed in earlier work, is applied to fans in three field sites to illustrate the use of fan morphologic characteristics in the analysis of debris-flow hazards. This approach should be taken as a first step in any debris-flow hazard mitigation project, particularly where extensive historical records do not exist.
