XPSWMM can aggregate 2D results for point, line and polygon into time series using the Time Series Outputs features,

  1. select the layer
  2. select the tool
  3. draw the point/line on the map

After running the model, two csv files will be created to report the time series, and the max. min values in the 2D output folder.

  • xx_PO.csv: time series
  • xx_POMM.csv: max/min values
  • xx: the model name

To review the time series,

Report for Polygon

If you need to get time series of a polygon, the XPSWMM user interface doesn’t support it yet. And you’ll need to use a Tuflow command to get it done.

  • add a line in the control file read the polygon from an GIS file
  • Read GIS PO == C:\temp\polygon.shp

prepare a shapefile,

  • draw the polygon
  • create 3 columns
  • Type: Qin_Qout_Vol means to report flow in/out and the total volume within the polygon
  • Label: the name of the time series for this polygon
  • Comment: any comment

The results are reported in the same csv files. But since it is not visible in XPSWMM, you need to plot it in Excel.
