Input Data Descriptions
The following example shows input data as created by running TEST 1C in
SAM.sed. Notice that there is a separate input data set for each sediment
transport function chosen in SAM.sed, with each data set ending with a $JOB,
and a $$END record at the end. Also notice that no data set contains any flow-
duration or hydrograph data.

$$END
In order to execute, the above data sets require flow information. This data is
input through the "Sediment Yield Input" screen and automatically written to the
CDFFIL file.
The flow information can also be in the ".yi" file, input using a system editor.
Note that the information must be put in each "stacked" job, i.e., in each data set
defined by a $JOB record. This format may be used to describe a flow-duration
curve using discharge and percent of time exceeded, or a hydrograph, using QH
records. See the Appendix E of this manual. The following examples show data
sets containing the water data the JP record, the QQ-QD record sets, and the
QH records.
