= Introduction =
QGIS is used to create time series plot outputs. Two types are described:<br>
:*2d_po line object - records average water level (_H) and flow (QQ_) across the line; and
:*2d_po point object - records water level (_HH_) and velocity (_VV_) in the cell where the point falls into.
<br>
 
Line 12:
<li>In the Run ID box write 'M01_001'.
<li>Tick the 'Lines' Geometry Type and hit 'OK'.
<li>The '''2d_po_M01_001_L.shp''' appears in the Layers panel.<br>
</ol>
Digitise a plot output line from left to right looking downstream. The direction of the line is important, the opposite direction would produce negative values:
Line 19:
<li>Digitise a line from left to right looking downstream across the floodplain and channel.
<li>Populate the attribute table as follows:
:* Type = H_Q_Q_
:* Label = Location1Loc1_L
<li>Toggle the editing off to save the edits.<br>

Digitise a plot output point in the channel where the 2d_po line crosses the channel:

= Conclusion =
:*The 2d_po layers were created, containing a line recording waterflow levelacross andthe flowline and point recording water level and velocity.
