Introduction
This tutorial shows how to use the Hydro Network functionality within in Delftshell. This tutorial is subdivided in:
- Working with Hydro Network. In this part you learn to create and adjust a Hydro Network.
- 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.
Working with Hydro Network
Create a new Hydro Network (Branches)
You have to start with a new project.
First you have to add an empty network to your project:
- Go to the Project Explorer.
- Rightclick on project1.
- Select Add - > New Data.
- Select Network.
- Press Ok.
In the same way you have to add a map:
- Go to the Project Explorer.
- Rightclick on project1.
- Select Add - > New Data.
- Select Map.
- Press Ok.
In the map navigator you can add a layer to the map:
- 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 network.shp.
Zoom to Extends
You can use Zoom to Extends to view the whole layer.
Now you can add the network to the map:
- Select Network1 from the project explorer.
- Drag the network on the map (central view).
Now you see in maps a treeview with the network as subset op the map and the network editor is active. You can start editing now!
You can create branches in two ways:
- Create New Branch, this option is used to draw very accurate. You can add curvepoints on exact locations.
- Create New Branch (Auto): With this option you can draw a Network fluently. Curvepoints are added automatically.
- Select Create New Branch (Point and Click).
- Draw one of the branches by clicking.
- Stop with a doubleclick.
Now you can try some network editing tools:
- Move Feature (smart), when you drag a node the network moves proportionally, when you drag a line, the network moves integrally.
- Move Feature, when you drag a node this individual node moves.
- Insert Cruvepoint in Branch, you can add curve points and move them to make the location of your network more accurate.
- Delete Object (gives error), you have to draw your branch again.
The endpoints of the branch are automatically assigned as boundaries (see map legend). Adding another branch to a boundary automatically changes a boundary to a normal node.
- Select Create New Branch(Auto).
- Connect the other branch to the first branch.
Now you can finish your network
- Again select Create New Branch(Auto).
- Draw a new branch downstream from the confluence.
Working with Cross-sections
There are two ways to add a cross section:
- Schematical: In this way you can add a cross-section on a specified location along the river.
- Geometry based: You put a cross-section on the exact measurement locations.
To add a schematical cross-section:
- Click Create Cross Section.
- Click on four locations along channel1.
To add a geometry based cross-section:
- Click Create Cross Section.
- Drag two lines perpendicular to channel2. Click on Select Feature(s) to stop creating cross-sections.
Now you can adjust the cross-sections in the Network view:
- Doubleclick on CS0001 in the network view.
- Click on Cross-section view.
- Adjust the bottom level(z) of cross-section 1 for example in <-5> m at y= 150m and <-8> m at 300m.
- In the same way, adjust the bottom level(z)of cross-section 2 for example in in <-15> m at y= 150m.
Toggle history
You can use Toggle History to compare cross-sections with each other.
- In the cross-section view, click on Toggle History.
- Click on cross-section CS0003.
- Click on cross-section CS0002.
- Click on cross-section CS0001.
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:
- From Sobek: You can import a network you used in previous versions of Sobek.
- 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.
- 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).
Import a network from vector layer (shp, gdb)
You can create a network based on a vector layer.
- Start with a new project.
- In the project explorer rightclick on project1.
- Click Add -> New Data -> Map -> Ok.
- Add a new layer to the map.
- Browse to river_sel.shp.
- In the project explorer rightclick on project1.
- Click Add -> New Data -> Network -> Ok.
- Drag the network to the map (central view).
- Select (using shift) the lines in the shape file.
- Click Network in the menu.
- Click Import Branches.
Now the branches are imported.
