= Introduction =
In this module, the creek is represented as a 1D open channel embedded into the 2D floodplain.<br>
Since the release of sub-grid sampling (SGS), 1D open channels may no longer be required if the DEM is at a fine resolution. If the DEM resolution is too coarse (for example in the below image), 1D open channel or quadtree may be required. The recommended approach is to use a quadtree model as demonstrated in <u>[[Tutorial_M07 | Module 7]]</u>, however, if the DEM is too coarse and cross section data is available, 1D open channel can be used. <br>

The GIS layers are:<br>
:*TGC layers:
<ol><ol><li>2d_code: A layer containing polygons that define the cell codes (active and inactive). </ol></ol>
<ol><ol><li>2d_zsh: A layer used to reinforce top of bank elevations. </ol></ol>
:*ECF layers:
<ol><ol><li>1d_nwk: A layer used to define culverts and open channels in 1D. </ol></ol>
<ol><ol><li>1d_xs: A layer used to reference cross section data. </ol></ol>
<ol><ol><li>1d_bc: A layer used to define 1D boundary conditions. </ol></ol>
<ol><ol><li>1d_wll: A layer used to define 1D water level lines (to display 1D results in 2D map outputs). </ol></ol>
:*TBC layers:
<ol><ol><li> 2d_bc: A layer defining the locations of 1D/2D boundaries.</ol></ol>
:*TCF layers:
<ol><ol><li>0d_rl: A layer defining the reporting locations.</ol></ol>

'''Module 11 builds from the model created in <u>[[Tutorial_M02 | Module 2]]</u>. The completed Module 2 model is provided in the Module_11\TUFLOW folder.''' <br>
<br>

=Part 1 - 1D Open Channel with Culverts=
Simulate 1D open channel model with culverts conveying flow beneath roads. 
== GIS Inputs ==
Create, import and view input data:
:*<u>[[Tutorial_M11_001_GIS_Inputs_QGIS | QGIS - SHP]]</u>
:*<u>[[Tutorial_M11_001_GIS_Inputs_QGIS_GPKG | QGIS - GPKG]]</u>

== Boundary Condition Database (bc_dbase) ==
Update the bc_dbase with a reference to the new weir outflow:
<ol>
<li>Navigate to the '''Module_11\Tutorial_Data''' folder. Copy the '''Weir_HQ.csv''' into the ''' Module_11\TUFLOW\bc_dbase''' folder. 
<li>Open the file, it contains a water level (head) versus flow boundary condition for the water leaving the model:<br>
<br>
[[File:M11_bc_dbase_01b.png]]<br>
<br>
<li>Save a copy of the '''bc_dbase.csv''' as '''bc_dbase_M11_001.csv'''.
<li>Open the file and add the additional weir boundary condition:<br>
<br>

<br>
<li>Save the bc_dbase.
</ol>

== Simulation Control Files == 
=== ESTRY Control File (ECF) ===
A new control file, the ESTRY Control File (ECF), is introduced. ESTRY is TUFLOW’s 1D hydraulic solver and includes all of the 1D files and commands.  <br>
<ol>
<li>Create a new text file '''M11_001.ecf''' and save it in the '''Module_11\TUFLOW\model''' folder.
<li>Add the following command lines: <br>

== Running the Simulation ==
Update the batch file created in the first part of Module 11 to reference the '''M11_5m_002.tcf''' file. Save the batch file and double click it in file explorer to run the simulation. <br>

== Troubleshooting == 
See tips on common mistakes and troubleshooting steps if the model doesn't run:
:*<u>[[Tutorial_Troubleshooting_QGIS | QGIS]]</u>

== Check Files == 
While the model is running, review the added features are specified correctly:
:*<u>[[Tutorial_M11_002_Check_Files_QGIS | QGIS - SHP]]</u>
:*<u>[[Tutorial_M11_002_Check_Files_QGIS_GPKG | QGIS - GPKG]]</u>

== Results ==
When the model is finished, review the results:
:*<u>[[Tutorial_M11_002_Results_QGIS | QGIS]]</u>
<br>

= Conclusion =
:*A model with 1D open channel embedded into 2D floodplain was created.
:*The 1D open channel conveyed flow underneath the roads through 1D culverts.
:*Bridges were modelled in 1D, with overflow occurring in the 2D for the upstream bridge and 1D weir for the downstream bridge.
