===GIS Layers===
The results are stored in GPKG layers, typically between 1 - 3 layers are stored in the result file depending on the output (one for point results, one for line results, one for polygon results). However there is no requirement against storing results from multiple model runs in a single GPKG, this is just not typically how outputs are written. <Br>
The column names of the GPKG layers should follow the convention below:<br>

The GPKG layers should have the following columns:

In this example the GIS layers are <code>M06_5m_003_swmm_ts_L</code> and <code>M06_5m_003_swmm_ts_P</code>.
