An extension to the Thomas‐Fiering Model for the sequential generation of streamflow

An extension to an algorithm for the sequential generation of nonhistoric stream‐flow, previously used by Thomas and Fiering, is suggested. The distinguishing features of this model are preservation of (1) normal distribution of annual flows; (2) log‐normal distribution of monthly flows; (3) correlation between annual flows; and (4) correlation between monthly flows. This model has been applied to two representative Pacific Northwest rivers. A graphical examination of the results suggests that this model provides an authentic representation of streamflow.
