A sewer network has been created, consisting of nodes, conduits, subcatchments, and other structures.
00:11
In InfoWorks ICM, there is a close relationship between subcatchments, land uses,
00:17
and runoff surfaces such that they can all be configured from the same window.
00:22
For this exercise, open the transportable database .icmt file that matches this tutorial.
00:29
A subcatchment describes an area draining to one or more inflow nodes.
00:34
A land use contains a list of runoff surfaces particular to the type of land use being defined, such as suburban or industrial.
00:42
A runoff surface describes the runoff characteristics of a specific surface type, for example, a road or roof.
00:50
From the Grid windows drop-down, click New subcatchments window.
00:55
This is where all the subcatchment information is stored in a table format.
00:59
There are 10 different tabs.
01:02
Right-click one of the yellow tabs and select Hide empty tabs.
01:07
Select the Runoff surface tab.
01:09
For each surface type, individual characteristics can be defined that determine how the runoff of rainfall occurs on that surface,
01:17
the volume of runoff, and the rate at which it enters the drainage system.
01:22
In this model, there are 4 runoff surfaces currently defined.
01:26
ID 1 is the default value given in the model.
01:29
Then, there are three runoff surfaces:
01:37
Click and drag the scroll bar to see the available columns of data.
01:41
Depending on which Runoff volume type and Routing model is used, the data columns become available.
01:47
All the available options should be populated for each runoff surface.
01:52
If the cells are grayed out, then you do not need to populate that data.
01:57
Change some of them to see the different combinations and fields that are required.
02:01
Note that in the Model menu, there is a Runoff surface wizard that helps you to define standard values for surfaces.
02:08
Navigate to the Land use tab.
02:11
This tab contains default values for several factors, including the percentage of total area for each Runoff Surface,
02:19
the Population Density, and the Connectivity.
02:22
Note that the DEFAULT value starts with every model.
02:26
The next ID is Urban land use, which is applied to the model.
02:30
The Runoff surfaces have been populated with the IDs from the Runoff surface tab.
02:36
InfoWorks ICM allows up to twelve runoff surfaces per land use to support the modelling of more complex mixed surfaces.
02:45
Switch to the Subcatchment tab.
02:47
This is where you define the individual characteristics of each subcatchment or contributing area.
02:53
Find the Land Use ID column.
02:56
This is where you set the Land Use from the previous tab.
02:59
These are all set to Urban, since that was chosen on the Land use tab.
03:04
Scroll to the Population column.
03:06
This is where you define the wastewater, trade, and infiltration flows into the sewer network.
03:13
These are the default values, unless other values are specified.
03:18
In the Model menu, under Subcatchment, there are tools to assist in applying population from point data or polygon data.
03:25
These tools use internal or external GIS layers to distribute the population for subcatchments, based on geo-spatial information.
03:34
Next, look at the Rainfall profile and Evaporation profile columns.
03:39
These relate to the Profile ID within a Rainfall Event, and can be used to apply different geo-spatial rainfall events across the catchment.
03:48
The SPR calculation, WRAP soil type, and HOST soil class columns should be set appropriately
03:55
based on the runoff volume method that is applied.
03:58
Look at the Area measurement type column and corresponding Runoff area % and Runoff area absolute 1-12 columns.
04:07
These define the amount of area used to generate runoff from each of the twelve surfaces, as defined in the Land Use.
04:14
If you change the Area measurement type from Absolute to Percentage,
04:19
then the percentage columns become available as you scroll to the right.
04:23
Conversely, the percentage columns are available when Percentage is chosen as the measurement type.
04:29
Click the Runoff surface tab.
04:32
Since there are only three surfaces listed here—Road, Roof, and Permeable—back on the Subcatchment tab,
04:39
only the first three Runoff area columns are populated with data.
04:44
When you are done exploring, close the Subcatchment window.
