How to import hydrograph data into the Inflow Control Center

Is there a way to quickly import hydrograph data for nodes in a model?


In previous versions of SewerGEMS and CivilStorm, hydrograph data that was stored in an Excel spreadsheet needed to be copied and pasted into the nodes for the Inflow Control Center. Starting with SewerGEMS and CivilStorm CONNECT Edition (build, with the latest patch), this data can now be imported into the Inflow Control Center.



1. Download and install version of a product listed above and apply the latest patch set available.

2. The hydrograph data needs to be in the correct format (“<element label>,<time>,<flow>”) and then saved to a Comma Separated Values (.csv) file type. Make sure to close the .csv file before proceeding.

3. The units used for the import are assumed to be the same as defined for "Time_Extended" and "Flow" in the hydraulic models unit options. Go to Tools > Options > Units and set the units "Time_Extended" and "Flow" to match the units used in the .csv file.

4. Import the data by going to Components > Loading > Inflow Control Center. Click the new icon and select "Import Hydrographs" from the drop-down list. Navigate to and select the .csv file, then click open. The hydrographs should be populated in the Inflow Control Center.
