Is it possible to run a multi-point trace analysis, where more than one source can be selected? Or, is it possible to track concentration of multiple constituents?
Problem ID#: 81530
This can be done with the Water Quality Batch Run tool, available starting with WaterCAD and WaterGEMS V8i SELECTseries 3 (08.11.03.17).
You can view results such as graphs, for the concentration of each constituent, volume of water from each trace source, etc. You can also view tabular reports of results and export for color coding.
The above tabular results are for trace analysis which shows trace results at each time step for all elements in the model. In trace analysis you can choose between multiple sources of trace and then check the trace percentage for all elements in statistics table by changing trace source.
CONSTITUENT
To perform batch run of constituents along with trace, you can select multiple constituents from alternatives as shown below and then see the concentration of each for selected elements. For this first you need to setup respective alternatives for the constituents and select those alternatives and respective scenario in water quality batch run window.
To view the graphs you need to select elements from drawing for which you want to see results in graphical format and in statistics format, results for elements are shown.
See additional resource below and in the Help.
Note that if you want to model the interaction between multiple constituents, you will need to use the Multi-Species Extension (MSX)
Note also if you are using version 10.00.00.55 and the results of a water quality batch run for trace do not match the results of a regular trace run, this is a known issue in that version (reference # 793707). To resolve this, either contact technical support for the latest cumulative patch set for 10.00.00.55, or upgrade to a newer version.
