Completing the hydraulic design in InfoDrainage

00:00

InfoDrainage is very powerful in its ability to calculate the appropriate sizes

00:08

and types of stormwater drainage system elements for you.

00:11

This is why, once you have successfully imported a CAD file that was started in Civil 3D,

00:17

you can complete the hydraulic design in InfoDrainage.

00:20

In this example, the manholes and pipes are all set at the same level and depth, all the way down the slope.

00:26

This is because they have not yet been designed to handle the correct amount of runoff for this area.

00:32

To begin, review the data for the first catchment.

00:36

Place your cursor over the catchment icon and click to open its properties.

00:41

In the Catchment – (1) dialog box, on the Runoff tab,

00:45

you can see that the Volumetric Runoff Coefficient has been set to 0.500,

00:50

and the Percentage Impervious is set to 100.

00:53

However, since this is a typical suburban development and only the hardstanding areas contribute to the percentage impervious,

01:01

change this to 60.

01:04

Optionally, you could perform a more detailed assessment of your subcatchments.

01:09

You could show the background surface data for all the roads and roofs

01:12

and then calculate the individual percentage impervious values for each subcatchment.

01:17

But for this exercise, the average value will suffice.

01:22

Next, enter a Time of Concentration of 5 minutes.

01:26

Also, set the Volumetric Runoff Coefficient to 0.75.

01:31

Again, these are typical values for these types of subcatchments.

01:35

The main idea here is that you do not need to accept the values that Civil 3D has provided.

01:41

You can change them to precise calculations or known values for the local area you are working on.

01:47

Rather than edit each subcatchment one at a time, you can make all your changes in a table.

01:53

On the ribbon, Build tab, Data panel, click Tables.

01:58

In the Tables dialog box, select the Inflows tool.

02:04

In the left pane, expand the Inflows node, and expand the Catchment Area node.

02:12

The options here control what data appears in the table.

02:15

Enable Preliminary Percentage Impervious, Preliminary Volumetric Runoff Coefficient,

02:21

and Volumetric Runoff Coefficient.

02:24

Then, expand Time of Concentration and enable Percentage Impervious.

02:29

In the Percentage Impervious column, select the first cell,

02:34

then click and drag to select all the cells.

02:37

Then, in the toolbar, enter 60 into the box and click the equals sign (=).

02:42

This changes the percentage impervious value for all the catchments in the model.

02:48

Notice that it automatically set the Preliminary Percentage Impervious value to 60 as well.

02:54

Next, select all the cells under the Volumetric Runoff Coefficient

02:58

and change those values to 0.75.

03:02

Notice that the Area values have all been calculated for you.

03:07

Click OK.

03:09

Now that the rainfall data and catchment parameters have been set up,

03:13

you can bring these together by configuring the analysis.

03:17

On the ribbon, Analysis tab, Critera panel, click Analysis Criteria.

03:23

In the Analysis Criteria dialog box, select both the All and FSR rainfall studies to enable them, and then click OK.

03:33

Next, you need to set up the preliminary sizing for the pipes.

03:37

On the ribbon, Preliminary Sizing tab, Network Design panel, click Network Design Criteria.

03:45

In the Network Design Criteria dialog, Flow Options tab,

03:49

expand the drop-down and select FSR.

03:53

Click the Design Options tab.

03:56

Here, you can choose to set a variety of pipe options,

03:60

including the pipe library, slope, level, backdrop, and velocity options, among others.

04:08

For this exercise, simply accept the defaults and click OK.

04:12

On the ribbon, Preliminary Sizing tab, Network Design panel, open the Network Design Wizard.

04:20

On the Select Flow Path page, you determine which pipes you want to design.

04:26

In this case, it is all of them, so click Next.

04:30

For the Enter Flow Criteria page, again, accept the defaults for the rainfall and click Next.

04:36

On the Enter Design Options page, accept the default options for the flow path and its network and click Next.

04:43

Lastly, on the Summary of Changes page, you can review the changes made during the network design.

04:50

Click Finish.

04:52

The Network Design Report opens, to provide you with a summary of the new pipe capacities

04:57

and flows for this drainage system.

04:60

Close the dialog.

05:02

Review the pipe profile again to see the changes to the flow path.

05:06

In the Tree View, click Flow Path, then right-click it and select Show Profile.

05:12

In the Profile – Flow Path dialog box, you can see how the design has changed.

05:17

There is a different gradient and the pipes are different sizes, both of which indicate the system has now been hydraulically designed.

05:24

To see the system data in greater detail, on the ribbon, Build tab, Data panel, click Tables.

05:32

To see the pipe data, click the Connections tab.

05:37

The table populates with the new pipe data, and specifically, the Diameter / Base Width column contains the new pipe sizes.

05:45

Click OK.

05:47

Now, with the design all done, save the network in InfoDrainage as Hydraulic Design,

05:51

so that you can bring it back into Civil 3D to complete the design.
