WS pro can model concentrations of
00:07
dissolved substances traveling through a network.
00:10
This includes turbidity,
00:12
cloudiness due to silt or other particulates caused
00:14
by a burst pipe or similar incident.
00:18
You can model turbidity with different scenarios
00:20
that include mitigation or no mitigation.
00:22
To see how they compare.
00:25
In this example,
00:26
you will simulate a turbidity incident and then a
00:28
hydran flush to see how it impacts turbidity.
00:32
First, open the bridge net network,
00:36
create a new scenario and name it E X three base.
00:39
This will be the scenario with no mitigation involved
00:44
in the GEO plan.
00:44
Pick a node in a location with a hydrant nearby downstream so
00:48
that a simulated hydrant flush will have a measurable impact on turbidity.
00:53
In this example, node
00:54
T 28366403 is selected with the idea that the pipe immediately upstream has burst,
01:02
double click the node to open its properties
01:06
in the properties window, expand water quality turbidity profile,
01:10
click the button with the ellipsis next to water quality
01:13
turbidity to open a dialogue where you can edit its profile
01:17
in the first row of the date time column set,
01:20
the start date and time to May 2nd 2022 at midnight
01:25
leave the turbidity set at zero
01:29
in the second row.
01:30
Use the same date as the first row, but adjust the time to one o'clock or 1300 hours
01:36
set the turbidity to 500
01:40
in the third row, use the same date and adjust the time to three o'clock or 1500 hours
01:46
set the turbidity back to zero.
01:49
Click, OK.
01:52
In the toolbar, click the manage scenarios button
01:55
and then in the notification click network
01:60
in the manage network scenarios, dialogue,
02:02
click create to open the create new scenario dialogue
02:06
in the new scenario, name field type X three dash mitigation,
02:11
then check the box next to copy an existing scenario
02:15
in the scenario to copy dropdown. Ensure that E
02:18
three base is selected.
02:20
Click OK.
02:23
With the X three mitigation scenario highlighted
02:26
in the manage network scenario's dialogue,
02:28
click select,
02:32
make sure you are working in the X three mitigation scenario.
02:35
Before continuing to the next step,
02:38
double click a nearby hydrant that is downstream from the node
02:41
where the turbidity is being modeled to open its properties,
02:45
expand hydrant flow profile,
02:47
then click the button with the ellipsis next to hydrant profile.
02:52
In the hydrant profile.
02:53
Dialogue set the start date in time to 2nd May 2022 at midnight
02:59
with an opening value of zero in the first row.
03:04
In the second row, use the same date and adjust the time to two o'clock or 1400 hours.
03:11
Set the opening value to 100 to simulate that the hydrant is fully open.
03:16
Note that this is one hour after the pipe burst
03:18
and introduction of turbidity at the node you selected earlier
03:23
in the third row, use the same date and set the time to 3 30 or 1500 hours and 30 minutes
03:31
set the opening to zero to simulate that the hydrant is closed.
03:36
Click OK.
03:38
Setting a maximum flow value limits the simulated flow
03:41
rate of water coming out of the hydrant.
03:44
This is to avoid interfering with other customers in the area
03:48
in the properties window. Enter a value of 15.0 in the maximum flow field,
03:55
then commit all changes before continuing to the next step.
04:00
Now it is time to create a new run.
04:04
In this example, the run is titled
04:06
three turbidity
04:09
check the box next to experimental
04:13
set, the start and end dates and times to two May 2022
04:17
three May 2022 at midnight respectively.
04:21
Set the computational accuracy to 0.1 liters per second.
04:26
The computational accuracy is generally increased for water quality
04:30
simulations to provide more accurate and stable results.
04:34
This also helps to provide results in parts of the network with low flows
04:40
in the run type group box, expand the dropdown and pick water quality
04:44
because you are simulating turbidity rather than a chemical or pollutant.
04:48
You will not bring any solute data into the water quality options.
04:52
Instead
04:53
in the turbidity group box, check the box next to do turbidity analysis.
04:58
Click OK.
05:01
In the schedule, hydraulic run dialogue scenarios,
05:04
tab ensure that only the X three base and X three mitigation scenarios are enabled
05:11
click run
05:14
when the run is complete, click and drag the X three base results to the GEO plan.
05:21
Create a new contour theme.
05:27
In this example, the new theme is called turbidity.
05:32
The field is set to sim dot Turbidity.
05:37
Adjust the value count to an appropriate number. In this example, it is set to eight
05:42
and customize fill colors to your preference.
05:47
Click OK?
05:50
In the GEO plan properties and themes,
05:52
dialogue disable the display of customer points and
05:54
polygons for a less cluttered visual layout.
05:57
Click apply then OK.
06:01
The turbidity incident being simulated is resolved
06:04
quickly within the 24 hour timeline.
06:07
Instead of clicking the play button in the toolbar to watch the entire simulation,
06:11
you can limit the scale of the timeline by clicking jump two slash replay
06:17
in the replay options, dialogue set the time to 1200 hours by adjusting the slider.
06:22
Then click set, start time,
06:25
click OK.
06:28
In the GEO plan,
06:29
click at different points on the timeline bar until you
06:31
see the color representing turbidity at the node you selected.
06:35
In this example, turbidity is shown as orange.
06:38
You can now graph various nodes within the area of turbidity.
06:41
To see how it changes over time.
06:44
Now click and drag the X three mitigation results to the GEO
06:48
plan to see how they differ from the X three base results.
06:52
Click through the timeline until you see the color representing turbidity appear.
06:57
Note how it dissipates faster than the X three base
06:59
results due to the hydrant opening at two o'clock.

InfoWorks WS Pro can model concentrations of dissolved substances travelling through a network. This includes turbidity—cloudiness due to silt or other particulates—caused by a burst pipe or similar incident. You can model turbidity with different scenarios that include mitigation or no mitigation to see how they compare. In this example, you will simulate a turbidity incident and then a hydrant flush to see how it impacts turbidity.
Start by creating a new scenario:
Next, pick a node in a location with a hydrant nearby downstream, so that a simulated hydrant flush will have a measurable impact on turbidity.
To create the second scenario:
Ensure you are working in the Ex3 – Mitigation scenario before continuing to the next step.
Note that this is one hour after the pipe burst and introduction of turbidity at the node you selected earlier.
To set a maximum flow value, limiting the simulated flow rate of water coming out of the hydrant and avoid interfering with other customers in the area:
Now, create a new run:
The Control and Demand Diagram populate automatically.
The computational accuracy is generally increased for water quality simulations to provide more accurate and stable results. This increase also helps to provide results in parts of the network with low flows.
Notice that because you are simulating turbidity, rather than a chemical or pollutant, you do not bring any Solute Data into the Water Quality Options dialog box.
Next, create a new contour theme:
The turbidity incident being simulated is resolved quickly within the 24-hour timeline. Instead of clicking the Play button to watch the entire simulation, limit the scale of the timeline:
You can now graph various nodes within the area of turbidity to see how it changes over time.
