Line 10:
The main advantages of using Quadtree are shorter run times (with considerable cell count reduction) and smaller size of output files. If longer run times of model without Quadtree are not an issue and output file sizes are fine then there is no strong argument to use Quadtree. Some models with cell count reduction only around 30% might be even running slower with Quadtree than the original HPC model.

The default for SGS models is to map the water level in its full extent and the rest of the data types as trimmed. This can be changed with the below commands:<br>
<font color="blue"><tt>SGS Map Extent Trim </tt></font> <font color="red"><tt>==</tt></font><tt> All </tt><br>
<font color="blue"><tt>SGS Map Extent Full</tt></font> <font color="red"><tt>==</tt></font><tt> h d v</tt><br>
Remap function that is part of the asc_to_asc utility can be used to post-process the result grids to a finer resolution DEM. See <u>[[TUFLOW_Remapping | TUFLOW Remapping]]</u>.
