This is a tutorial of level 'beginner'. If you have not done so, familiarise yourself with the DeltaShell User interface first here. This tutorial was set-up together with the University of Twente. A basic understanding of hydrodynamics is assumed. |
The purpose of this tutorial is to get familiar with the D-Flow-1D module for channel hydraulics. In this tutorial we will set up a simple single-channel model and do basic output viewing.
...
The system we are going to model is a relatively simple 350 km single-channel river model with a compound channel cross-section.
A working flow model needs at least the following things:
- a network (consisting of branches and nodes)
- at least 1 cross-section
...
- per branch
- a computational grid
- boundary conditions
- initial conditions
To make viewing output easier, it also recommended to add observation points.
- Open SOBEK and add a new 'Flow 1D Model' from the 'New Model' button.
- Take a moment to explore the project explorer and see what components make up a Flow1D model. (If you don't know what the project explorer is, please review these terms here)
- Open the network by double clicking Flow1D/input/network from the project explorer.
- Start by creating a branch from the Ribbon (tab: Map, group: Network). For now, do not use the 'freeform' tool.
- You should now see the something like below in your network. If your network looks differently (too many branches, or curved branches), simply select the branches and press 'Delete' in your keyboard to remove the branches and try again.
