6.7. Mapping

6.7.1. Results are not imported in TWW

Use processing tool join attributes to add the results stored in the tables Node summary and Link summary to the tables tww_od.vw_wastewater_node and tww_od.vw_tww_reach. The mapping should be done on the attribute obj_id of the tww_od tables and the attribute id of the summary tables.

6.7.2. Results are imported in TWW

• Add the layers tww_swmm.node_results and / or tww_swmm.link_results to your QGIS project

• Filter by the name of the simulation and the name of the parameter to show: Right click on the layer > filter > Expression: "swmm_simulation_name" = 'name of the simulation AND "swmm_parameter" = 'inflow'

Two template QGIS files are provided in the plugin folder src\swmm_templates\*.qgs

The project swmm_summary.qgs show how the summary indicators can be loaded in QGIS. The project swmm_full_report.qgs show how the full time series can be loaded in QGIS. You will need to adapt the services and the filters.

6.7.2.1. Show the indicators evolving along time

This manipulation only works with complete times series. Namely, you need to import the full results and not only the summary.

Play the simulation with Time Manager

• Install / activate the plugin Time Manager

• Parameter > Add a layer

  • Start time: time

  • End time: Same as start

• Time frame size: Same as the swmm export time step

Plot values along the time with DataPlotly

• Install / activate the plugin DataPlotly

• Graph type: Scatter Plot

• Activate: Use only selected features

• Choose the layer

• Field X: time

• Field Y: value

• Marker type: Line

• Select the object that you want to plot: every nodes or links with the same id (you can select them from the map or from the table).
