=Introduction=
This page details the method for using QGIS to create the GIS based boundary layer. The layer will be populated with the name of each inflow boundary which will be linked to the boundary database in the following steps of this module. The created boundary will be applied as a source-area boundary in a 2d_sa layer. 
=Method=
'''Boundary Condition Database'''
<li>Copy the file '''100yr2hr_loc.csv''' from '''Module_data\Module_02\Inflow''' and place it into the '''TUFLOW\model\bc_dbase''' folder. This file contains the four hydrographs that will be used.
<li>Open up the latest version of the boundary condition database. This is located within the '''TUFLOW\model\bc_dbase folder''' and is called '''bc_dbase_FMT_M01.csv'''.
<li>We need to add four additional rows to the file which reference four additional inflows. The revised bc_dbase should look like the figure below: 
 
[[File:100yr2hr_loc_csv.png]] 
 
The hydrographs applied to each of the 2d_sa polygons are contained within the source file '''100yr2hr_loc.csv'''. 
[[File:100yr2hr loc.PNG|800px]]
 
<li>Save the bc_dbase as '''bc_dbase_FMT_M02.csv'''. It is now ready to be used within the model.
 
<li>Copy the layer '''2d_sa_FMT_M02_001_R.shp''' within the '''Module_data\Module_02\Inflow''' folder into the '''TUFLOW\model\gis''' folder.
<li>Open the layer in QGIS. Four polygons have been digitised over the location of the proposed development. Each polygon represents a sub-catchment to which different inflow boundaries will be associated.
<li>Turn on Toggle Editing mode. Populate the first and only attribute of each polygon with the name of the inflow boundary . The next steps of this module will link these boundary names with an inflow using the bc_dbase located in '''TUFLOW\bc_dbase''' .

<li>Save the layer '''2d_sa_FMT_M02_001_R'''.

A GIS layer has been created containing four polygons in a 2d_sa layer over the location of the proposed development. The existing boundary conditions database (bc_dbase) has been modified to link these four GIS objects to hydrographs within an external csv file.
