by adding the measured suspended-load and the computed bedload relations.
The mean-annual total-sediment load transported by mcrements of discharge
may be computed by combining this relation with the average frequency of
discharge recorded at the gaging station.
The cumulative frequency of daily mean discharges at a gaging station for
the period of record may be represented by a streamflow-duration curve. The
flow-duration curve shows the percentage of time a given discharge is equaled
or exceeded. When several years of record are used to construct a tlow-dura-
tion curve, the resulting relation describes the average or probable frequency
of various discharges during a year. The streamflow-duration curve for the
Little Snake River near Dixon, Wyoming, gaging station is shown in Fig. 3.
