Introduction

This tutorial shows how to use the Hydro Network functionality within in Delftshell. This tutorial is subdivided in:

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.

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.

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:

1. Create New Branch, this option is used to draw very accurate. You can add curvepoints on exact locations.
2. 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:

1. Schematical: In this way you can add a cross-section on a specified location along the river.
2. 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.

• 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:

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.

• 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.
