<br />erosion and estimates of recurrence interval: Geology, v. 6, no. 4, p. 200-204.
<br />
<br />Channel erosion in tributaries of Colorado's Big Thompson River was studied
<br />following the 1976 flash flood. In two catchments, no measurable erosion
<br />occurred. Erosion in other catchments was intense (maximum observed sediment
<br />yield = 308 cu m/ha). Relationships between 'total' storm precipitation (P) and
<br />sediment yield give values for the maximum potential sediment yield at a given
<br />storm magnitude. Sediment mobilization begins when P = 140 to 150 mm, or when
<br />short-term rainfall intensity = 140 to 170 mm/h. Qualitative and quantitative
<br />evidence suggests that a large, rare event is needed to modify the Big Thompson
<br />tributaries geomorphically. Catchment denudation values were used to estimate the
<br />recurrence interval of the 1976 event; the results suggested the possibility that
<br />previously estimated recurrence intervals may be too long by factors of 1.6 to 8.
