Sample Output Data
The following example is taken from the output from Test 6A. The general
tables, Tables 1 and 0-3, are described in the normal depth calculation output.
The output shown below is the additional, riprap output. The first line describes
the calculation being performed. The next line states the source of the riprap
sizes tested. It would have stated "USING QUARRY RUN RIPRAP" had that
been prescribed. The first table shown describes the necessary riprap size as
determined by the calculations. The second, longer table describes both the
riprap and some of its effects as well as some of the factors used in the
calculations. The cross section properties are echoed, and there is a table with
the "Hydraulic properties with riprap in place." The standard tables, 8-4 and 8-5,
are repeated but contain the parameters as calculated with the stated riprap size in
place.
