River modelers generally build their river networks from survey data.
00:08
The first stage in building a river reach is to import the necessary survey data,
00:14
such as cross section lines, section data, and the river reach center line.
00:20
As with other imports in InfoWorks ICM, this is done using the Open Data Import Centre (ODIC).
00:29
In this exercise you will import pre-prepared survey cross section data, river reach centre line data and node locations.
00:39
Right-click a model group and select New InfoWorks > InfoWorks Network.
00:45
Name the network “1D River Model”, and then click OK.
00:51
Double-click the network to open it in the GeoPlan.
00:55
You can now start importing several sets of data into your model.
00:60
First are the cross-section surveys.
01:02
From the Network menu, select Import, and then select Open Data Import Centre.
01:09
For the first import, from the Table To Import Data Into list, select Cross section line.
01:17
In the Data Source section, set the Source Type to CSV.
01:23
Click the Browse (…) button, navigate to the folder of the exercise files for this tutorial, and then select Cross_Section Lines.csv.
01:35
Click Open.
01:36
Back in the ODIC, in the Field Mapping Configuration section, click Auto-Map.
01:43
Click Import, and then OK to complete the import.
01:48
Much of the data associated with rivers and structures is held in subtables.
01:54
Therefore, it is necessary to first create the objects before populating the subtables with data.
02:01
In the Subtable list, select Cross section line: Section data.
02:07
Click the Browse (…) button, and then select Cross Section Data.csv.
02:13
Click Open.
02:15
Click Auto-Map and notice that new Import Fields are set to be imported.
02:21
Click Import, and then OK to complete the update.
02:26
A river junction or inflow point is always a break node.
02:31
This has no definable area but allows connectivity between the link objects.
02:37
In this example the node locations have been pre-defined.
02:42
From the Table To Import Data Into list, select Node.
02:47
In the Data Source section, set the Source Type to CSV.
02:52
Click the Browse (…) button and select Break_Nodes.csv.
02:59
Click Open.
03:01
Back in the ODIC, in the Field Mapping Configuration section, click Auto-Map.
03:07
Click Import, and then OK to complete the import.
03:12
The break node data is imported.
03:15
Next the river reach centre lines are to be imported.
03:20
In the Table To Import Data Into list, select River reach.
03:26
In the Data Source section, set the Source Type to Raw Shape File.
03:32
Click the Browse (…) button, select River Centre Line.shp, and then click Open.
03:41
In the Field Mapping Configuration section, click Auto-Map.
03:46
Click Import, and then OK to complete the import.
03:51
Close the Open Data Import Centre.
03:54
Survey data is displayed on the GeoPlan as a series of lines.
03:59
The blue lines represent cross-section data.
04:03
Double-click one of the cross sections to open the Properties window.
04:08
In the Section data field, click the More (…) button to access and view the data.
04:14
Close the Section data window.
04:17
Where additional data is required, this can be added manually within the ICM interface.
04:23
Commonly the cross section X, Y, Z data will have been provided by a surveyor although it may need reformatting.
04:32
The node and river centre lines could either be derived outside of ICM and imported,
04:38
as per this example, or, manually created within ICM from mapping once the cross sections are imported.
04:47
When adding a node that will be placed on top of a cross section line,
04:51
it is important to make sure that it is snapped to one of the points on the cross section.
