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.
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 new data;
- Select network (down in the menu).
In the same way you have to add a map:
- Go to the project explorer;
- Rightclick on project1;
- Select new data;
- Select map.
In the map navigator you can add a layer to the map:
- Select add layer;
- Browse to .... river network.shp;
- Use the buttons "zoom to extend" to view the layer.
Now you can add the network to the map:
- Select the network 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 curve points : You can add curve point 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 Channel 1.
To add a geometry based cross-section:
- Click create cross-section;
- Drag two lines perpendicular to Channel 2.
(* Click op select feature to stop creating cross-sections)
Now you can adjust the cross-sections in the Network view:
- Doubleclick on cross-section in the network view
- Click on cross-section view
- Adjust the bottom level(z) of cross-section 1 for example in -5m at y= 150m and -8m at 300m;
- In the same way, adjust the bottom level(z)of cross-section 2 for example in in -15m at y= 150m.
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 3;
- Click on cross-section 2;
- Click on cross-section 1;
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
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 new data;
- Select map;
Now a map is added in the project explorer.
- Select the network from the project explorer;
- Drag the network on the map (central view).
