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.

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:

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 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:

1. Schematical: In this way you can add the cross-section on a specified location along the river.
2. Geometry based: You put cross-section on the exact measurement locations.

To add a schematical cross-section:

• Click create cross-section;
• Click on four locations along Channel 1.

Plaatje schem

To add a geometry based cross-section:

• Click create cross-section;
• Drag two lines perpendicular to Channel 2.

Plaatje Geometry

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;

To add a cross-section, click
