Note: This is mix and match. Either the flow, or quality, or both, input files can be hand-crafted.
# simplest-style qwdata file # # Lines beginning with # are comments, and can appear wherever. # Note, though, that the magic column-decoder line does NOT begin with a comment character. # sample_dt p00410 1993-02-08 240 1993-04-01 175.5 1993-04-26 174.5 ...Notes:
Normally, you would provide a site_no column, although it's optional:
# # Typical hand-crafted qwdata provides site name, date, and concentration value. # site_no sample_dt p00410 05030150 1993-02-08 240 05030150 1993-04-01 175.5 05030150 1993-04-26 174.5 ...In this case, I provided a column of site_no, and provided a value for every line. Otherwise, half my data would be "05030150" and half set to "" for a site name. This site name is a string, not a number. I can name my site "Xiangdong Province, CN" if I wish (no tabs).
You can also provide a flow value with your concentration value, if you want. Label it "p00060" on the column decoder line:
# # Hand-crafted qwdata with site names and a flow value. # site_no sample_dt p00410 p00060 05030150 1993-02-08 240 98.00 05030150 1993-04-01 175.5 05030150 1993-04-26 174.5 ...In this case, I also provided a column of p00060 - this is streamflow in ft3/sec. Notice that I only provided a value for this column on one line. That means for that 1993-02-08 only, I insist on a streamflow of 98.0 for calibration purposes, instead of whatever the flow file says. (I could also have provided flow values for the whole column if I wanted to.)
The site name and flow columns are independently optional - I could drop either or both. I could also provide p00061 instead of p00060 for flow. It is also possible to have multiple concentration columns for your element. Whatever column(s) your concentrations are in, though - say, p00410 and p90410 - must be on the list of elem codes you tell LoadRunner to look for.
