The conveyance calculated for river sections is important for the accuracy and stability of a model.
00:10
If you have abrupt changes in roughness or slope, then you may need to set a panel marker at each change.
00:17
This is a manual process if they are not included in the original import.
00:22
The panel markers assist in the calculation of the conveyance curve that is used during simulations.
00:29
To complete this exercise, copy the network out of the transportable database .icmt file for this tutorial.
00:41
From the Database, double-click the 1D River Model to open it on the GeoPlan.
00:46
From the Modelling Grid Windows toolbar, select New lines window.
00:52
Right-click in the table margin of cross section 16 and select Find and select in geoplan.
00:60
From the More GeoPlan Tools toolbar, click Conveyance Graph Pick,
01:05
and then click the selected cross section to open the graph of this cross section.
01:10
It should be a smooth curve from the bottom-left to the top right.
01:15
This curve’s conveyance currently drops back down as the elevation increases, which can cause simulation instability.
01:24
You can correct this by adding panel markers to aid the calculations.
01:29
Close the graph window.
01:31
Select Tools > Options.
01:34
In the Options window, switch to the General tab.
01:39
Enable Allow editing of river reach data, and then click OK.
01:44
This allows you to directly alter the river section data.
01:48
Otherwise, you must update the cross section line data first, and then build the river reach section data again to update it.
01:57
Click the Select tool, and then double-click the 16DS river reach to open the River reach Properties.
02:05
In the River sections row, click the ellipsis (…) button to open the sections data.
02:11
For Section 16, enable New panel for rows 7 and 34 at the top of the banks where there is an abrupt change in slope,
02:20
especially on the left hand side.
02:23
The panel markers are indicated in the graph by vertical blue lines.
02:28
Click OK.
02:29
Once again, click Conveyance Graph Pick, and then click the 16DS cross section to open the graph.
02:38
The graph line is now smoother and monotonic.
02:42
At this point, you can commit your changes without validating.
02:46
Click Commit changes to database.
02:49
Add a comment of “River section data imported and checked”, and then click OK.
02:56
In the validation popup, select No, since this model contains errors as it is not fully connected.

The conveyance calculated for river sections is important for the accuracy and stability of a model. If there are abrupt changes in roughness or slope, then a panel marker may not need to be set at each change. This is a manual process if they are not included in the original import. The panel markers assist in the calculation of the conveyance curve that is used during simulations.
To complete this exercise, copy the network out of the transportable database .icmt file for this tutorial or carry on from the previous exercise.
It should be a smooth curve from the bottom-left to the top right. The conveyance of this curve currently drops back down as the elevation increases, which can cause simulation instability. To correct this, add panel markers to aid the calculations:
This allows the river section data to be altered directly. Otherwise, the cross section line data would need to be updated first, and then the river reach section data would need to be built again to update it.
This adds panel markers at the top of the banks where there is an abrupt change in slope, especially on the left hand side. The panel markers are indicated in the graph by vertical blue lines.
The graph line is now smoother and monotonic.
