Description :
Observations were made in the Tuolumne, Merced, San Joaquin, and Kings River drainages during the 1982 to 1993 period. Of the 36 debris flows observed, 6 were examined in detail to provide specific data on this phenomenon. Triggering events for debris flows in the southern Sierra Nevada include intense rainfall, rain-on-snow storms, and seasonal melting of heavy snowpacks. Movement typically occurs at depths between 0.3 and 5 m below ground surface.
