Sample Input Data
The following example shows input data when calculating ks. Note the KN
record in Test 4B, and field 6 on the CT record in Test 4A. The negative values
flag the program to make the hydraulic roughness calculations. The absolute
value, i.e., 0.5in Test 4B, tells the program the ratio of roughness in that element
to the composite roughness. For example, if the values are -1, as on the KS-
record fields 3, 4, 5, and 6, or as on the CT record in field 6 in Test 4A, then the
roughness in each of these panels would be calculated as equal proportions of the
composite. The program is supposed to supply "missing" values on a record by
repeating the data in the previous fields; i.e., on the CT record, the data for fields
7 and 8, and 9 and 10, would be repeated from fields 5 and 6 (see Appendix C).
Note, however, that currently this does not work for the KN record, and data for
all fields should be supplied by the user.
