Abstract

Streamflow fluctuates in time in response to the annual cycles of precipitation and temperature and to random deviations from these cycles. The resulting lowest flow for each year, usually an average for some number of consecutive days, is designated as an annual low flow. That flow usually occurs during a period of no precipitation and is derived from ground-water discharge or surface storage being discharged from lakes, marshes, or melting glaciers.
