Title
The effects of debris flows on stream fine benthic organic matter (FBOM), characteristics, 1996
Abstract
The biochemical characteristics of fine benthic organic matter (FBOM) were studied in 14 stream reaches. Half of these low-order mountain stream reaches had experienced significant debris flow events during server winter storms and half did not.
