Output Data Description
Table 1 echoes the input data file. An un-numbered table lists the "Bed
Sediment Fractions Calculated From PF-Data." The properties of water, Table 3,
are calculated from the water temperature at sea-level. The hydraulic parameters
from input data are listed in Table 2.1. Effective discharge is the product of the
width, depth, and velocity and represents channel discharge. Table 4.1 presents
detailed results of the sediment transport calculations by discharge, in rows by
sediment size class and in columns as labeled. Notice the discharges are the total
discharges from the QW-record. Concentration is calculated using total
discharge, not channel discharge. There will also be a separate Table 4.1 for
each sediment transport function selected in the input file. Only two discharges'
output for each function are shown here.
The Van Rijn function provides additional printout for each water discharge,
the sediment concentration profile by size class is calculated in mg/l. Table 5 is
a summary of the calculated total bed-material sediment discharge, in rows
according to water discharge and in columns by sediment transport function.
Sample of Data Written to SAM.yld Input File
SAM.sed writes the sediment concentration rating curve calculated for each
sediment transport function selected to the SAM.yld input file, as shown below.
