An Approach to the Selection of a Streamflow Base Period
Abstract
Wyoming streamflow records were examined to determine if
base periods exist. A base period is a shorter period of record
which exhibits the same statistical characteristics as the longer
record and can therefore be used in simplifying the study of water
resource projects.
It was determined that, for twenty-three representative streamflow
gaging stations selected, the twenty-year period 1948-1968 provides
sufficient information for use as a base period.
