Abstract
Average annual sediment discharge in Pacheco Creek basin,
Contra Costa County, Calif., was larger during August 1965-April 1970
than the historical annual sediment discharge (1909-62) by a factor of
about 1.3. This increas in sediment discharge is attributed primarily
to an increased frequency of peak streamflows and to a larger average
annual streamflow during the 1965-70 period.
