<li>Open the files, either:
:*Within the QGIS Browser Panel, navigate to the 10m, 5m and 2m check file
▲::*'''M08_10m_001_grd_check_R'''
:*In File Explorer, navigate to the '''Module_08\TUFLOW\check''' folder, drag and drop individually the 10m, 5m and 2.5m check file database (e.g. '''M08_5m_001_Check.gpkg''') into the QGIS workspace and select the grd check layer.▼
▲::*'''M08_5m_001_grd_check_R'''
▲::*'''M08_2.5m_001_grd_check_R'''
▲:*In File Explorer, navigate to the '''Module_08\TUFLOW\check''' folder, individually drag and drop
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>The grd_check is the 2D grid defined by the 2d_code layer and contains a region object for each cell. It is useful to understand how the model is orientated, the cell size in relation to the hydraulic features and where certain calculations occur in the model. In this tutorial, the grid is orientated to align with the downstream road.
<li>Compare the cells, inspect how the smaller cell size picks up topographic features compared with the larger cell size. <br>
