once you have decided on which rainfall methodology will work for your site,
00:07
you can begin to create the drainage network in your model.
00:10
Starting with the no surcharge state.
00:14
This model already has catchment areas set up with
00:16
a manhole in each and pipes connecting the manholes.
00:21
The flow arrows between the pipes designate the flow direction.
00:25
The next step is to create rainfall data to be used in the network design wizard
00:31
for this training.
00:32
We will be using Fs our data but only because it is freely available
00:38
for a real project. We would probably use F E H rainfall
00:42
but the input for that would have to be purchased from a third party.
00:47
Note that the design process is the same for either said of U. K. Rainfall
00:52
on the ribbon
00:53
rainfall pollutants. Tab rainfall panel,
00:56
click rainfall manager.
00:59
The rainfall manager, dialog box opens
01:03
on the left in the tree view,
01:05
ensured the design storms, node is expanded
01:08
here. You choose the type of rainfall methodology you are designing for
01:13
for this example select F. S. R.
01:16
But realize that you may have different standard rainfall theories showing here,
01:20
depending on where you are located in the world,
01:23
click F. S. R. To highlight it
01:25
and then in the toolbar, click add
01:29
the right side of the dialog box is populated with
01:31
the FS are parameters return periods and storm durations,
01:37
ensure the parameters tab is active
01:40
In the label Type Box
01:42
called This Test Rain one.
01:45
Under the parameters,
01:46
click the check boxes for both summer and winter to enable them
01:51
keep the England and Wales region active
01:54
for the M 5 60 millimeter type box, enter 20.0 and for the ratio our value enter 0.400.
02:05
These values are representative of the south of England,
02:09
click the return periods tab,
02:11
ensure that the used checkboxes active and under return period years,
02:16
enter to
02:18
the increased rainfall percentage value is used when you need to enter an
02:21
allowance for climate change but it will not be used in this exercise,
02:27
click the storm durations tab
02:29
here, you can choose the storm durations you want to include in your design.
02:35
Some users like to choose all of them thinking to
02:37
test every eventuality but that is not generally necessary.
02:42
Use the buttons on the right to make your selection
02:46
For this exercise,
02:47
click default and you can see that a nice range of storm durations are chosen for you
02:52
from only 15 minutes up to a whole day.
02:56
You could also choose to enable or disable some more storms in the table.
02:60
But for this exercise
03:01
leave it set to the defaults.
03:04
Note that some catchments are susceptible to short storms
03:07
and others longer events.
03:09
So it is important to select a range of storm durations
03:14
info drainage has the ability to save
03:16
the rainfall separately from the catchment data.
03:19
The advantage of that is you can create a rainfall event
03:22
here and then use that same rainfall data across different studies
03:27
in the toolbar, click save
03:30
browse to the folder where you want to save the rainfall study
03:34
for this exercise.
03:35
Select the save work here folder,
03:39
name the file such as
03:40
design rainfall,
03:42
and then click save
03:44
back. In the rainfall manager, click OK to finish creating the rainfall data.

Once you have decided on which rainfall methodology will work for your site, you can begin to create the drainage network in your model, starting with the no-surcharge state.
This model already has catchment areas set up, with a manhole in each and pipes connecting the manholes. The flow arrows between the pipes designate the flow direction. The next step is to create rainfall data to be used in the Network Design Wizard.
IMPORTANT: The rainfall method you use is dependent on your local standards. This example is in the UK and uses the FSR data.
Here, you choose the storm durations you want to include in your design. (It is not necessary to choose them all.) When you click Default, a nice range of storm durations are chosen for you, from only 15 minutes, up to a whole day. Note that some catchments are susceptible to short storms and others longer events, so it is important to select a range of storm durations.
