Abstract

The AA. mapped the debris flows from color aerial photography and inspected many of them in the field. Three processes initiated debris flows : mobilization of shallow landslides in thick, often well vegetated, colluvium; transport of material eroded from steep unvegetated hillslopes via a system of coalescing rills; the firehose effect which occurred where overland flow became concentrated in steep bedrock channels and scoured debris from talus deposits and the heads of debris fans. Based on field observations and examination of soils mapping, the AA. identified a relation between the degree of soil development and the process type that generated debris flows
