one useful feature of info drainage is its ability to import
00:07
old models that have already been created in micro drainage.
00:10
The predecessor to info drainage
00:13
start a new model,
00:15
then on the ribbon import tab micro drainage panel click import design
00:22
at this point you may be prompted to save the info
00:25
drainage file so save it to the save work here directory
00:30
navigate to where the micro drainage file is saved in this case,
00:33
the data folder and select the full digitized model and open it.
00:39
You are prompted to re save the network
00:41
to overwrite the file that has just been created
00:45
at this stage. You may receive an import warnings notification.
00:49
This is because there are parameters in micro drainage that info
00:53
drainage does not consider relevant and therefore they cannot be imported.
00:58
For example,
00:59
micro drainage allows users to define pimp classifications and maximum rainfall,
01:05
but these need to be configured in info
01:07
drainage because the catchment areas are calculated differently
01:11
and the rainfall theory and micro drainage no longer applies
01:16
similarly.
01:17
The analysis criteria from micro drainage does not
01:20
matter because it will be redone in info drainage
01:24
click OK to import the micro drainage model into the plan view
01:29
in this example,
01:30
you can see that the model in info drainage appears
01:33
essentially the same as it does in micro drainage.
01:36
However,
01:37
keep in mind that the underlying mathematics and
01:39
simulation engines are different between the two programs.
01:44
Neither of the programs are right or wrong in their model representations,
01:48
both are giving their approximations of how
01:51
this drainage system would operate in reality,
01:55
there are some types of data that info drainage
01:58
can represent that cannot be modeled in micro drainage.
02:01
One example is full backwater effects,
02:04
such as if there were a river or tidal influence downstream.
02:09
In that case you would have to use info drainage to create an accurate model,
02:14
but for a single pipe run where the pipes are not sir charged.
02:17
Both programs should provide similar results.
02:21
Micro drainage has three areas in which you can specify design rainfall,
02:26
namely the pipe design criteria,
02:28
the single simulation criteria and the seasonal return period wizard.
02:34
All three are imported into info drainage
02:38
to see them on the ribbon
02:40
in the rainfall pollutants tab, select the rainfall manager.
02:45
The rainfall manager dialog shows all three rainfall simulation areas
02:49
for the imported micro drainage data,
02:53
selecting each of the F. S.
02:54
Are nodes,
02:55
shows the parameters you can set for each of the simulations in micro drainage.
03:01
The srp wizard is most commonly used
03:03
for its ability to run many storms simultaneously
03:07
so that the worst storm can be chosen for each location,
03:11
click cancel to exit the dialog.
03:15
The one edit that is usually required to micro drainage imports,
03:18
is to change the percentage impervious value for all sub catchments.
03:24
This is extremely important otherwise
03:27
flows could be significantly over predicted
03:29
in comparison with the old micro drainage results,
03:33
click the build ribbon,
03:35
then the tables button
03:37
in the tables dialog, click the inflows tab,
03:40
then expand the inflows items until you see
03:43
both the percentage impervious and the preliminary percentage impervious
03:49
enable both of these check boxes
03:51
so that they appear in the grid to the right
03:54
click and drag to highlight the whole of the percentage impervious column.
03:58
Then type 60 into the value box above
04:02
and then click the equal sign.
04:04
Both columns should change to 60,
04:08
click OK,
04:10
select the analysis tab in the ribbon.
04:12
Then click analysis criteria
04:16
in the dialogue. You can set a variety of parameters for a rainfall simulation.
04:21
Make sure the checkbox next to srp wizard F. S. R.
04:25
Is enabled and the design and some criteria boxes are disabled.
04:31
The number of storms should now show 18.
04:35
Set the output interval to five minutes
04:38
and the time step to default
04:41
click okay to accept the changes,
04:44
select the analysis tab in the ribbon,
04:46
then click validate
04:49
the validate. Dialogue would show errors in the model if any existed
04:53
in this example, there were no errors.
04:55
Click OK. To close the dialog.
04:59
It is best practice to save your model. Prior to running the simulation
05:03
when you're ready, click go
05:06
info drainage will show progress bars during the simulation process
05:11
as well as how much time has elapsed
05:14
the simulation times can vary depending on your machine's capabilities.
05:19
Once the simulation is complete,
05:21
a connection summary dialog shows details of the results.
05:26
Click critical storm
05:28
and the dialogue updates. To highlight the impact of the worst simulated storms.
05:34
Close the dialog,
05:36
you can then gather and view the results in a
05:38
variety of ways by selecting the options in the results,
