Level events define level hydrographs for inputs to the network during a simulation.
00:08
A level hydrograph is typically used to represent seawater or river levels.
00:14
For 1D networks, level hydrographs can only be applied as an outfall node.
00:19
If a level hydrograph is applied to any type of node other than an outfall, it will be ignored during a simulation.
00:26
When carrying out 2D modeling in InfoWorks ICM, level hydrographs may also be applied to 2D boundary objects.
00:33
Level data is usually contained in a spreadsheet.
00:37
For this tutorial, you import a level event.
00:42
Before importing an inflow event, it is a good idea to create a new model group to store all your event data.
00:50
Right-click your existing Model Group and select New InfoWorks > Model Group.
00:57
In the New Name – Model Group popup, name the group “Ancillary Files” and then click OK.
01:04
From the Model Group, right-click the Ancillary Files group and select Import InfoWorks > Level > From event file.
01:16
In the Open dialog, navigate to the folder with the downloaded files for this tutorial and select Mean High Water Springs.lev.
01:26
Click Open.
01:28
The imported file appears under the Ancillary Files group.
01:33
Right-click Mean High Water Springs and select Open As.
01:37
From the Select Format popup, select Editor, and then click OK.
01:44
The level event contains profiles for multiple outfall locations.
01:49
An individual column is required for every node.
01:53
Right-click any cell and select Profile properties.
01:58
In the Properties window, you can set the Node reference and Pipe level or datum fields.
02:04
Be aware that when you are setting values for levels, all values should be relative to the same datum level.
02:10
A national datum level may be used, or you could choose your own datum, such as the invert level of the lowest conduit in the network.
02:18
If the datum level used is above the level of some or the entire network, the hydrograph may contain negative values.
02:25
In this case, a potentially large increase in level will occur if the default value of zero is used.
02:32
When you are finished working with the level data, close both the Properties and the Editor.
