3.15.1Plot Output (PO, LP) from 2D Domains

Time-series data output from 2D domains is available for a range of hydraulic parameters as listed in Table 4 .17. Output takes the form of time-series hydrographs (referred to as PO – Plot Output) or longitudinal profiles over time (LP). All data types are available for PO and only H_ (water level) is available for LP.

The locations of PO and LP output must be defined prior to a simulation. This is carried out by creating one or more GIS layers containing points, lines and polylines that define the locations of PO and LP output. Figure 4 .10 illustrates how 2d_po objects are interpreted.

The start time for PO and LP output and the output interval is set separately to map based output using Start Time Series Output and Time Series Output Interval. If no start time or interval is set, output occurs from the beginning of the simulation at every timestep.

The output is in the form a .csv files and also to the _TS.mif file (as of Build 2003 06 AA). Refer to Section 6.3.2. As of Build 2003 06 AA, 2D domain time-series (PO) output is synchronised with 1D domain output by default. This allows both 1D and 2D time-series to be placed in the _TS.mif file. Set Output Times Same as 2D to OFF in the .ecf file if 1D and 2D time-series data is not to be synchronised. In this case, no 2D PO is written to the _TS.mif file.

Table 4 .18 describes the GIS attributes. Of note is for flow flags, TUFLOW sums time-series with the same label (this does not apply if the label is left blank).
