Delta Shell - is an integrated modelling environment. The main idea of the Delta Shell is to provide one application as a platform which can be used to integrate various models and tools. It is achieved by use of a software framework specifically focused to provide a set of components which can be re-used by environmental models.
Recent version of the Delta Shell can be obtained in the Download section. It also includes instructions on installation and minimum system requirements.
In the first development phase SOBEK, Delft3D will be integrated into the Delta Shell.
Delta Shell is currently in active development. Feel free to contact us if you interested in development by sending email to: contact.
This tutorial provides a general overview of the application files as well as brief introduction of the most common user operations, which are available in the program.
When you have finished the installation, doubleclick at your desktop on the icon "Delta Shell - Flow 1D"
=> This will start 'Delta Shell'
How to start with a 1-D model?
When application is started - it automatically creates a default empty project so an user can immediately start filling it in with data, models, etc. A project can be seen as a currently opened user work document. An active project can be stored in SQLite database file format. Eventually DeltaShell may store a model input / output data in a set of NetCDF files located next to the project file. So in total there are two non-proprietary file formats used to store project data.
To start with an empty project:
Rightclick on 'Project1' in the Project Explorer
Choose 'Add' > 'New Model' > 'Flow model 1D'
Doubleclick on 'Network' under 'flow model 1d (1)' in the Project Explorer
A new tab appears with an empty map
To start with an imported SOBEK Model:
Righclick on'Project1' in the Project Explorer
Choose 'Import' > 'SOBEK model'
Navigate to the .LIT Map
Doubleclick on the file 'Network.tp'
How is the user interface organised?
Description of the windows
The main graphical user interface is organized as a set tool windows and document windows. A difference between those two is that the tool windows are always shown on the screen and the document windows are only used to visualize or edit a specific data type.
Typical examples are:
Project Explorer - the main navigation window showing all data contained in the current project in a tree view.
Map Contents - tree-like window showing the list of the GIS layers in the currently opened map.
Message Window - logging windows, messages sent from models or different parts of the system are placed here.
Network Table View - Shows properties of the selected network in a table.
Properties - shows properties for an active selection of the graphical user interface.
Network Contents- allows to view / edit structure of the currently opened (hydro) network.
Time Series Navigator - allows to navigate through times of any time-dependent data.
Adjusting the grafical user interface with dockable windows
You can easily adjust the grafical user interface by dragging the dockable windows with you left mouse button.
Select a window header (e.g. project explorer)
Keep your left mouse button pressed while dragging the window to the place you want
Release your left mouse button
Tip: You can always select a window with the'View'-button on the menu bar
Tip 'Map as leading window' Some users like to use the map as leading window 'Kaart centraal'. Watch next movie to see how you can arrange your dockable windows like that.
How is data organised in the Project Explorer?
All model input and output data can be navigated via the Project Explorer tree view.
How does the map work?
You can present Geografical data in two ways
-Doubleclick on items in the Project Explorer: A new map is opened for this specific item.
-Open a empty map (Rightclick on 'Project', 'New Item' > 'Map') and drag different items from the Project explorer on the map. In this way you can combine information on one map.
With the window 'Map Contents' you can show, hide and adjust layers within the active map.
Conventions usability
In general Delta Shell works with the following convention:
Button/Key
Action
Esc
Stops you action and returns to select tool
Leftclick
Selects an item
Rightclick
Gives a contex menu with possible actions
Doubleclick
Show a map or editor
Note: this is a alpha build. Some functionality is not tested well and may not work at all!
