Line 16:
The following are output from the tool:
* Output point layer - an output log from the tool identifying potential continuity errors
* [[1D_Integrity_Tool_-_Flow_Trace_-_Long_Plot|Plot window]] (if the long plot processing option is selected)
===Processing Options===
Line 28:
<li> '''Angle Check''' - will flag locations where the angle between the incoming pipe and outgoing pipe is less than the given input angle (180 deg is straight). Will only flag locations where this is true for all incoming and outgoing pipes at any given junction.
<li> '''Ground Cover Check''' - requires an input DEM. Will flag locations where the distance between the pipe obvert and ground elevation is less than the input threshold.
<li> '''[[1D_Integrity_Tool_-_Flow_Trace_-_Long_Plot|Generate Long Plots]]''' - Creates an interactive plotting window with long plots to help visualise the network. The outputs from the continuity check will also be flagged in the long plot. The behaviour of the tool can be modified depending on the number of channels initially selected when the tool is run:
<ul>
<li> One channel selected - will select all upstream network objects and generate a long plot for each unique network branch (e.g. if the pipe system splits upstream of the selected channel, a long plot will be generated for both branches).
Line 34:
<li> Three or more channels selected - similar to when two channels are selected, but will generate an extra branch for each extra channel selected (e.g. selecting 3 channels will create 2 branches starting from the most downstream channel). Currently 5 selected channels is the upper limit to stop this from accidentally being triggered for too many branches.
</ul>
''Note: substantial improvements have been made to the long plot functionality in terms of speed, plot interaction, and behaviour in TUFLOW Plugin Version 3.3. It is recommended to use at least this version
<li> '''Use Previously Selected Channels''' - this will select the channel lines that were used the previous time the Flow Trace tool was run. This saves the user the effort of manually reselecting the starting line(s) each time they run the tool and allows for quick iteration of the flow trace tool.
</ul>
