type

Any combination of the two letter flags listed in Column 1 of Table 4 .17 (limit of 10 flags per entry). In Version 3 or later, the flags are not case sensitive. Note, in Version 3 or later, “u ” has changed to “uu” and “v ” to “vv”.

For example, to output water level and flow time-series for the same line, enter “H_Q_” for the type attribute of the line.

T

label

Label up to 30 characters defining the name of the time-series. The label appears at the top of the columns of data in the _PO.csv file. Spaces are permitted, but do not use commas.

Note: If the same label occurs more than once for a flow output, the time-series are added together as one time-series. This allows a flow line that is not straight to be specified as a series of individual lines (this is effectively the same as using a GIS polyline). NB: If using fixed field format, neighbouring grids must be used to end and start two flow lines, ie. don’t use the same grid to end a line and then start the next line. Leaving the label field blank for several output locations does not activate this feature (this is for backward compatibility with Version 1).
