1. Working with Hydro Network. In this part you learn to create and adjust a Hydro Network.
2. Import of a network. In this part you learn how to import existing networks. Data you need for this tutorial is attached to this wiki page

For this tutorial you need some data files. You can download these files here. Please download and unzip these files before you start with this tutorial.

Working with Hydro Network

...

• Add a new layer to the map by using the rightclick > Add Layer or pressing the Add New Layer button on top of the map navigator.
• Browse to river_sel.shp.

...

Now you see cross-section related to cross-section 2 and 3.

Working with Structures

The functionality of structures is under construction.

• add structures
• compound structures

Import a network

This section describes two possibilities to import a network:

1. From Sobek: You can import a network you used in previous versions of Sobek.
2. From vector layers (shp, gdb): You can import vector layers to create a new netwerk.

Import a network from Sobek

To import a network used in a previous versions of Sobek:

• Start with a new project.
• Click on File.
• Click on Import data.
• Choose Sobek network file.

Image Removed

• Browse to Loenen.lit.
• Select folder 1.
• Select network.tp.

To view the network on a map:

• Rightclick on project1.
• Select Add Data.
• Select Map > Ok.

Now a map is added in the project explorer.

• Select the network from the project explorer.
• Drag the network on the map (central view).

• Create a network with branches and a cross-sections on each branch.
• Select create weir from the structure tools.
• Click on a branch to create a weir.
• On another branch, put two weirs on the same location to create a compound structure.
• Select create pump from the structure tools.
• Click on another branch to create a pump.

The structures are added to the network. Now we can adjust the settings.

• Click on the weir.

Image Added

You see the cross-sectional view of the weir with the nearest cross-section in the background. The default settings of the weir are OK.
The cross-sectional view cannot be displayed when there is no cross-section on the branch.

• Click on the compound structure

Image Added

You see the cross-sectional view of a compound structure with the nearest cross-section in the background. This compound structure consist of two weirs, but more weirs or other structures can be added. The background is colored red as a warning, because the two weirs overlap. To adjust the weirs:

• Click on the weir in the cross-sectional view.
• Adjust the width of one weir in 50m.
• Click on the other weir in the cross-sectional view.
• Adjust the offset in 250m.
• Adjust the width in 50m.

Image Added

The indication of overlapping structures (red background) is gone

To adjus the settings of the pump:

• Click on the pump.
• Deselect the control level on the delivery side.
• Adjust the control levels on the suction side in -4m for switch-on and -5 for switch-off.

1. From vector layers (shp, gdb): You can import vector layers to create a new netwerk.
2. From SOBEK: You can import a network you used in previous versions of SOBEK.

Import a network from vector layer (shp, gdb)

...

Now the branches are imported.

Import a network from SOBEK

To import a network used in a previous versions of SOBEK:

• Start with a new project.
• Click on File.
• Click on Import data.
• Choose SOBEK network file.

Image Added

• Browse to Loenen.lit.
• Select folder 1.
• Select network.tp.

To view the network on a map:

• Rightclick on project1.
• Select Add Data.
• Select Map > Ok.

Now a map is added in the project explorer.

• Select the network from the project explorer.
• Drag the network on the map (central view).
