Time Series Plots allow users to visualize how water quality constituents change over time at specific locations within the model, such as reaches and junctions. These plots are useful for tracking trends in water quality, such as changes in temperature, concentration, or other constituents during the simulation period. How to access the time series plot:
For Reaches:
For Junctions:
- Similar to reaches, right-click on a junction in the map window.
- Select Plot WQ Time Series from the popup menu to display the water quality time series plot for the junction.
Note: When selecting a junction, the time series plot will display data for the Water Quality Cell immediately downstream of the junction.

Observed Data can be overlaid on Water Quality Time Series Plots to compare real-world measurements with simulated water quality results. This is a powerful feature that allows users to validate the water quality model, check the accuracy of simulations, and assess the performance of the model. Observed data are accessed through the Observed Data Icons on the map panel. When observed data is linked to a specific reach or junction, it will automatically appear on the corresponding time series plot. Additionally, the plot includes reference values for the selected constituent (Observed data vs Model data Plot).

The Water Quality Time Series plots also enable users to view multiple constituents by selecting them from the constituent menu (Observed Data plot- Multiple Constituents).

Animation Control
The animation controls work similarly to video controls, allowing users to view the animation results (Animation Control). Users can adjust the delay by selecting the Options menu within the Animation dialog.

Animation Control
The larger the Play Delay number, the slower the animation will play, allowing for a more detailed view of the water quality data over time (Observed Data plot- Multiple Constituents).
