Line 22: 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_Scenario2/'''. 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 and Execution== ~~[edit]~~===TUFLOW Fixed Grid Model===▼ The TUFLOW model directly reads the provided ESRII ASCII DEM raster format, to set the extent of the computational domain and interpolate elevations at the 2D cell centers, mid-sides and corners. The boundary locations were digitized in GIS layers. The provided GIS land use layer was directly read for assigning roughness values.▼ Simulation results were viewed using SMS and GIS software. Calibration high water marks were loaded into a GIS layer and displayed within the GIS mapping to easily view the calibration performance of the model. TUFLOW’s 3D surfaces of peak water levels and depths were imported into the GIS to generate flood extent outlines.▼ ▲[edit]TUFLOW Fixed Grid Model ▲The TUFLOW model directly reads the provided ESRII ASCII DEM raster format, to set the extent of the computational domain and interpolate elevations at the 2D cell centers, mid-sides and corners.

The design was such that elements follow bathymetric contours and likely flow directions. Also ensure that narrow flow channels are well resolved and elements lie along center of flow channel. ~~Create mesh, automatically generating geometry (z) values from the DEM.~~ ~~Setup input files, consisting of one input file and 3 boundary condition time series (csv files).~~ ~~Run simulation on Dell Laptop 64 bit Intel i7 2.8 GHz CPU.~~ ~~Several simulations performed with varying Manning’s friction applied.~~ ~~Within SMS, load shape file with high water marks and point inspect model results of maximum water level. Export to Excel, convert to feet.~~ ~~Export 3D water level and depth surfaces into GIS to produce maximum flood extent polygons.~~ =Relevant Files=
