=Model Setup=
This section provides an overview and discussion of the model domain setup.<br> All files required to re-run the model can be found at '''FMA_Challenge_Models/FMA_Scenario1/'''. It is at your discretion which GIS package, text editor and method of model simulation to use (batch mode or within the text editor).
==Computational Domain Assembly==▼
TUFLOW directly reads GIS data layers to construct models. The layers used/created for Challenge 1 are:▼
<ol>▼
<li>A DEM TIN created from the provided terrain data (2ft contours) and exported to ESRI ASCII format as a 2ft DEM grid. When TUFLOW reads this DEM it interpolates the elevations onto the 2D computation grid.</li>▼
<li>GIS layers of cross-section locations and 1D network including structure details.</li> ▼
<li>GIS land-use layer digitised in .shp format.</li> ▼
<li>GIS layer of 1D/2D interface lines along the left and right banks of the channels.</li> ▼
</ol>▼
All model inputs are independent of the 2D grid cell size, orientation and extent, allowing for different 2D resolutions, dimensions and orientation to be easily simulated. ▼

Peak flood depths and water levels were exported to ESRI ASCII grids, and the flood extent was created by contouring the grid into a single region. Flows are outputted in .csv format and directly loaded into Excel. Profiles were created using the post processing utility TUFLOW_to_GIS and outputted into a .csv file.
