QGIS TUFLOW Apply Stability Styling: Difference between revisions

This tool styles the selected layer using a 'traffic light' method to indicate where instabilities could be occurring. This tool currently only supports the _TS.mif (_TS_P.shp) 1D output, however it is intended to expand the scope of this tool in future releases to other inputs and outputs to help with model checking.<Br>

''Introduced in version 3.3.14''<Br><br>

* '''Detailed Description Rule 1:''' Flag as unstable if the minimum value is less than zero ''(only applied to "Possibly Unstable")''

* '''Detailed Description Rule 2:''' Flag as unstable if the minimum and maximum values occur within '''<tt>FORWARD_LOOK_COUNT</tt>''' number of timesteps. This will not be flagged if the minimum value occurs at the first timestep.

* '''Detailed Description Rule 3:''' The following rule uses a <tt>'''TOLERANCE'''</tt> value defined as

<pre>TOLERANCE = PERC_DIFF_BETWEEN_MAX_AND_TS multiplied by the time series range (time series max value - time series min value).</pre>

: Flag as unstable if the max value is outside of the time series byequal to, or greater than the '''<tt>TOLERANCE</tt>''' value (outside means either not close to any of the data points or an interpolated value if the time of max falls inbetween data points)<br>

* '''Detailed Description Rule 4:''' Same as rule 3 however with the minimum value rather than the maximum value

* '''Detailed Description Rule 5:''' The following rule uses a <tt>'''TOLERANCE'''</tt> value defined as

<pre>TOLERANCE = UNSTABLE_PERC_LIMIT multiplied by the time series range (time series max value - time series min value).</pre>
