name | anything can go in here |
curve | the name of the text file with the curve values it, in units of feet and cubic feet per second |
Inv | invert, or low point of the structure |
in riser | option for flow into a riser structure |
out | option for flow out of a riser |
dam | option for flow directly through a dam |
This is a generic performance curve representing an outlet structure. The text file must be of the form:
...Curve:
depth(ft) flow(cfs)
1.0 4.23
1.2 5.13
3 4.2
7.0 10
...
The key string "Curve:" starts the reading of input value pairs, after a skipped line assumed to be the table header. Value pairs are separated by spaces, one pair to a line. A blank line at the end will terminate the reading of input pairs. Anything else in the file before or after this key word and sequence is ignored. You may need to specify the complete path and file name, depending on your system setup.
