Flood Modeller Tutorial Module01 Provisional: Difference between revisions

In this module we will link an existing 2D TUFLOW domain to an existing Flood Modeller 1D model. The TUFLOW 2D domain will represent the floodplain in the study area, and the 1D Flood Modeller model will represent the watercourse and all online, in-channel structures.

 

 

Setting up a 1D/2D model where the 1D channel cuts through the 2D domain is probably the most time-consuming type of a model to setup. For this module, the complete Flood Modeller 1D model has been provided, to allow for progressing through the module in a relatively short period of time.

This tutorial builds upon the 2D TUFLOW domain that was constructed as part of [[Tutorial_M01 |Module 1]] and [[Tutorial_M02 |Module 2]] of the TUFLOW Tutorial Model.

The steps necessary to modify each of the GIS inputs are demonstrated in QGIS using SHP and GPKG formats. If you would like to view instructions for the tutorial in ArcGIS or MapInfo these can be found on the archive page for[[Flood_Modeller_Tutorial_Module01_Archive | Tutorial Module 01]].

 

This part of the module creates the GIS layers that specify the location of the Flood Modeller nodes that are to be connected to the 2D domain.

This part of the module creates the 1D/2D boundaries to link the Flood Modeller 1D component to the TUFLOW 2D domain.

This part of the module defines the bank elevations of the watercourse which are the elevations of the 1D/2D boundary links created in the previous section.

This part of the module describes the steps to deactivate the 2D cells where the 1D model is replacing the 2D solution.
