= Introduction =
QGIS is used to view the 2D grid and mesh 2D results (as well as the TUFLOW 1D results). This section describes how to view the following results using the TUFLOW Viewer 2:
:*The '''grid results (.tif)''' are inspected with the '''Profile Tool plugin'''. For installation, see <u>[https://wiki.tuflow.com/index.php?title=QGIS_Profile_Tool Installation of Profile Tool]</u>
:*The '''mesh results (.xmdf, .tpc)''', including the bed elevation and time series, are inspected with the '''TUFLOW Viewer 2''' as part of the '''TUFLOW Plugin'''. MoreFor more information on TUFLOW Viewer 2 documentationand includinginstallation installationinstructions, please see the <u> [https://docs.tuflow.com/qgis-tuflow-plugin/2026.0latest/tuflow-viewer/installation/ TUFLOW Viewer 2 installation]</u>. For installation of the TUFLOW plugin, please see <u>[https://wiki.tuflow.com/index.php?title=TUFLOW_QGIS_Plugin#Installation_of_Plugin Installation of TUFLOW PluginDocumentation]</u>.

:* In File Explorer, navigate to the files above and drag and drop them into the QGIS workspace.
<li>The Map Outputs show scalar datasets, e.g. depth and velocity, and vector datasets, e.g. velocity vectors. Only one scalar and one vector dataset can be displayed at the same time.<br>

<li>SelectIn the layers panel, select '''M01_5m_001'''. fromIn the Layers'Layer Styling' Panepanel, then in the 'Datasets' tab, click on the scalar dataset 'Depth' under the Result Type. Using the 'Temporal Controller', hit the Play icon and "Go to next frame' icon to scroll through the output times. The results update as new output times are selected. </li>
