The InfoWater Pro Water Quality (WQ) Calibrator
00:08
provides a fully automated approach to accurate and efficient pipe network calibration, based on water quality.
00:15
When calibrating a hydraulic network model using water quality parameters, the goal is as follows:
00:23
to determine the best set of pipe wall coefficients producing the lowest overall deviation
00:30
between numerically simulated model results and observed field data at specified locations in the system.
00:38
Observed field data consists of chemical or other constituent concentration measurements.
00:44
Prior to performing a WQ calibration,
00:48
you need to run a simulation using InfoWater Pro’s Chemical/Temp Water Quality simulation option.
00:55
You can then access the WQ Calibrator through the InfoWater Pro App Manager.
01:01
Once you open the WQ Calibrator app, you can specify data parameters for pipe wall coefficients and junction concentration,
01:11
set calibration options, run the calibration simulation, and view the simulation results.
01:19
You can then export changes to your model based on the results, or use the results for further comparison and investigation.
01:28
In the Pipe Wall Coefficient Group tab, you define the pipe groups to be used in the calibration analysis.
01:36
In addition, you can modify any pipe group previously identified,
01:41
input ranges of acceptable pipe wall coefficients for each pipe group,
01:46
assign a level for each pipe group, and color-code each pipe group.
01:51
In the Junction Concentration tab,
01:55
you input field measurements for constituent concentration and sample time for selected junctions
02:01
that are to be used in the WQ calibration analysis.
02:06
Before running a WQ calibration simulation, you can specify optimization properties and simulation options.
02:15
From the Run menu, click Options.
02:19
In the WQ Calibration Options dialog, set key run setting thresholds and termination criteria.
02:27
The solution refinement process terminates when one of the four termination criteria is satisfied.
02:35
Advanced genetic algorithm (GA) options are also available, but you usually do not have to change these settings.
02:44
You can read more about these advanced settings in the InfoWater Pro Online Help.
02:50
In the Convergence Method section, choose one of the three available fitness equations,
02:56
noting that Type #2 is the typical selection for a WQ Calibrator simulation.
03:03
To run the WQ calibration, from the Run menu, select Start.
03:08
You can monitor the progress and performance of the simulation on the Run tab.
03:14
Once a WQ calibration simulation has been performed, you can click the Run Summary tab to review output results,
03:23
and review output values on the tabs where you specified data parameters.
03:29
On the Junction Concentration tab,
03:33
you also have the option to graph the correlation between observed and simulated junction concentrations.
03:40
If you are satisfied with the WQ calibration simulation, use the Export tab to export new pipe wall coefficients back into your model.

The InfoWater Pro Water Quality (WQ) Calibrator provides a fully automated approach to accurate and efficient pipe network calibration, based on water quality.
Goal when calibrating a hydraulic network model using water quality parameters:
Observed field data consists of chemical or other constituent concentration measurements.
Prior to performing WQ calibration, need to run simulation using Chemical/Temp Water Quality simulation option.
Then, WQ Calibrator can be accessed through InfoWater Pro App Manager to:
Use to:
Use to input field measurements for constituent concentration and sample time for selected junctions to be used in WQ calibration analysis.
Can specify optimization properties and simulation options.
Select Run > Options.
In the WQ Calibration Options dialog box, set key run setting thresholds and termination criteria.
The solution refinement process terminates when one of four termination criteria is satisfied.
Advanced genetic algorithm (GA) options are also available—usually these settings do not need to be changed.
Read more in Autodesk InfoWater Pro Help topic, Calibration Options - Advanced Genetic Algorithm (GA) Options.
Under Convergence Method, choose one of three fitness equations—Type #2 is typical for WQ Calibrator simulation.
Select Run > Start.
Use Run tab to monitor progress and performance of simulation.
Once complete, select Run Summary tab to review output results, and review output values on tabs where data parameters were specified.
Switch to Junction Concentration tab to graph correlation between observed and simulated junction concentrations.
If satisfied with WQ calibration simulation, use Export tab to export new pipe wall coefficients back into model.
