6.6.1. SWMM Import Results

6.6.1.1. Measurement tables

If you want to store the results in TWW and use the dedicated view for the mapping then use SWMM Import Results. It parses the report file of SWMM. The results are imported in the measurements tables in the tww_od schema:

measuring_point: there is one measuring point for each wastewater structure and simulation,

tww_swmm/images/tww_od_measuring_point.jpg — Measuring point: the name of the simulation appears in the remark

measuring_device : there is one measuring device for each measuring point,

tww_swmm/images/tww_od_measuring_device.jpg — Measuring device

measurement_series: there is several measurement series for each measuring point, one for each measured parameter (i.e average depth, maximum depth, maximum hgl …),

tww_swmm/images/tww_od_measurement_series.jpg — Measurement series

measurement_result: there is one or several measurement result for each measurement series. There is one value if the summary only is imported and many values if the full time series are imported.

tww_swmm/images/tww_od_measurement_result.jpg — Measurement result

and they populate a view dedicated for the mapping (see Results are imported in TWW).

6.6.1.2. Launch import

Launch SWMM Import results:

SWMM report file: the .rpt file generated during the previous step
Database: The name of the PostgreSQL service hosting the TWW database.
Simulation name: The name that you want to give to this simulation (it will appear in tww_od.measuring_point.remark).
Import summary: Only the summary is imported.
Import full results: The full time series will be imported. Attention, if the report step is small, the import can take a long time.
Import Max HGL in tww_od.wastewater_node.backflow_level
Import Max/Full Flow in tww_od.reach.dss2020_hydraulic_load_current

Warnung

Attention, a report file created from the SWMM GUI don’t contain the full time series but only the summary.

6.6.2. SWMM Extract Results

If you don’t want to store the results in TWW, this function generates two QGIS tables from a report file. You can map the values with the geometries (see: Results are not imported in TWW).

Launch SWMM Extract results:

RPT file: the .rpt file generated during the previous step
Node summary: a table layer which stores the simulation results.
Link summary: a table layer which stores the simulation results.
Cross section summary: a table layer which stores the simulation results.
