''Note: A downfall of this method in MIKE, is that elevations in the .dfs2 grid could have been manually modified such that the area outside the flood extent has a constant ‘Land’ elevation. Inspection of the terrain data before use is highly recommended. ''
=Creating a TUFLOW Boundary Control File from MIKE=
= Model Conversion Utility (FLO2D_to_GIS.exe) =
The flo2d_to_gis.exe utility creates a complete TUFLOW model from FLO-2D model data. The utility converts the following data into a TUFLOW compatible format:
* Model origin, grid orientation, extent and resolution information
* Topography datasets
* Landuse delineation
* Storage adjustment features
* Width reduction factors (flow constriction features)
* Inflow/outflow locations
* Boundary condition time series data
=Creating a Boundary Control Database file from MIKE=
These datasets are written to the standard TUFLOW model folder structure. TUFLOW control files are also output (tcf, tcg, tbc, boundary condition database).

''Note: This utility is currently still in its beta testing phase. Output should be carefully quality checked. ''

== Utility Execution ==
The TUFLOW Model Conversion (TMC) file is used to define the input files and projection information required by the utility. Steps how to create a TMC file and run the utility are as follows:
<ol>
<li> Place a copy of the flo2d_to_GIS.exe utility in the same location as the FLO2D model files.
<li> Create a new text file in the same location as the FLO2D model files. The name must have the extension ".tmc". For example the file name could be "run_model_Conversion.tmc".
<li> Enter the relevant command syntax (shown in italics below).
<li> The model conversion can be run either by dragging the TMC file onto the flo2d_to_GIS.exe utility, or from a batch file. Steps to create a batch file are:
<ol>
<li> Create a new text file in the same location as the TMC and FLO-2D files. The file name must have the extension ".bat". For example, "run_FLO2D_to_GIS.bat".
<li> Reference the executable, specify the batchfile flag (-b) and the TMC file name within the text file. Additional conversion references can be specified in series to process multiple models in sequence, for example: <ol>''flo2d_to_GIS.exe -b conv1.tmc''</ol><ol>''flo2d_to_GIS.exe -b conv2.tmc''</ol><ol>''flo2d_to_GIS.exe -b conv3.tmc''</ol>
<li> Double click the batch file in windows explorer to execute the model conversion.<br>

<u>Description:</u> Convert a FLO2D model into TUFLOW format using a mif coordinate projection line from
FLO2D FPLAIN == FPLAIN.DAT
FLO2D CADPTS == CADPTS.DAT
FLO2D INFLOW == INFLOW.DAT
FLO2D OUTFLOW == OUTFLOW.DAT
FLO2D ARF == ARF.DAT !#Optional
MI Projection == CoordSys NonEarth Units "survey ft" Bounds (1910000, 14400000) (2000000, 14500000)
== Utility Output ==
flo2d_to_gis.exe will convert the FLO-2D model into a working TUFLOW model titled: ''conv_001.tcf''
[[File: Flo2d_tcf.JPG]]<br>
The following items from the FLO-2D model will be included within the TUFLOW model:
* Model origin, grid orientation, extent and resolution
* Topography (elevation) datasets
* Landuse delineation information (non-varying with depth)
* Storage adjustment features
* Width reduction factors (flow constriction features)
* Inflow/outflow locations
* Boundary condition time series data
* Output interval commands
The TUFLOW model time step will be set based on a pre-defined ratio of the model grid size. This value should be reviewed by the modeller and updated if necessary.

== Model Conversion Limitations ==
Some FLO-2D datasets will not automatically be translated across to the TUFLOW model. These items can be manually added to the model using the commands listed below:
* Depth varying manning's n (shallow n): ''Read Materials File == <file>''
* Distributed hydrology rainfall inflow data: ''Read GIS RF == <file>''
* Infiltration and evaporation data: ''Read Soils File == file.tsoilf''
* 1D channel data: ''ESTRY Control File == <.ecf_file>''
* Levee breakline features: ''Read GIS Z Shape == <file>''
* Dam and levee breach data: ''Read GIS Variable Z Shape == <file>''
