Tutorial Module01 Archive: Difference between revisions

To conclude, in this module we have created a 2D TUFLOW model. We have setup the required GIS and text based inputs and ran the simulation. We have visualised the results and reviewed the performance of the model.<br>

The model results, depths and velocity outputs look sensible. However, the model has a slight issue with mass balance, which appears in the main channel areas. This is most likely caused by the inadequate representation of the creek with the cell size adopted in the tutorial model. This cell size has been chosen to allow the model to be simulated quickly on most computers.<br>

In Module 3 we will model the creek area as an embedded 1D open channel, this should minimise the mass area noted in this tutorial. Reducing the cell size also allows for a better representation of the channel in the 2D model.<br>

See the <u>[[Tutorial_Module01_Archive#Advanced_-_Model_Resolution_.28Optional.29 |Optional Section]]</u> below, in which we look at halving the cell size and the effect this has on the model results and simulation time.

Whilst reviewing the results, you may have noticed that the water was being held behind these road embankments (which were essentially acting as dams in the model. We will embed 1D culverts through the road embankments in <u>[[Tutorial_Module02_Archive |Module 2]]</u>. This will introduce the 1D control files and linking of the 1D model to the 2D.
