Handout Water Module

This handout can be used with one of the training courses we offer.

Advise is to print this handout and use it during the training to take notes on. Afterwards, you will have an overview of what you have learned during the training. This handout does not form a standalone tutorial. For a tutorial regarding the Water module, see the Rainfal Overlay tutorial.

The subjects in this hand out are:

• Create a New Project
• Add water depth data
• Add the Rainfall Overlay
• Walkthrough of the Water overlay Wizard

Create New Project

1. Click in the Main Menu on New Project
2. Provide a name for the New Project (max 20 characters) and click on Empty Project.
3. For the location, fill in Kockengen and click on Enter. Move the square with the left mouse button. The part of the map in the square will be your 3D world. With the sliders on the right side, it is possible to enlarge the square. However, the smaller the square is, the faster the 3D model will be generated. For the following steps, choose a size of max 2 x 2 km.
4. Then click on Advanced Options
5. Here you can check datasets that are used to generate the 3D world. By default, the IMWA data source is checked by which Culverts are automatically imported (if they are available for your location in the open dataset). If you have your own Culvert dataset, you can uncheck the IMWA data source here. Also make note of the DEM resolution. Select a high DEM resolution to use the most accurate AHN data.
6. Finally click on generate map to generate the 3D world from open data.

Import depth of water terrains

Note that it is not possible to return to the original heightmap. Therefore it is stronly advised to work with different verisons of your project, to always have the opporunity to go back to a previous version in case something went wrong with importing data.

1. Hover over de knop Overlays en klik op Add Heightmap. Nu wordt de hoogtekaart toegevoegd.
