QGIS Version 3.34 or newer, and QGIS TUFLOW Plugin 3.11 or newer are required to access the SWMM Processing Tools described in the following sections. For installation, see <u>[https://wiki.tuflow.com/
Define the Coordinate Reference System (CRS), also called ‘Projection’, for the QGIS workspace:

<li> Add the following command to the '<tt><font color="green">Time Control</font></tt>' section. This command is necessary for many TUFLOW-SWMM models, especially when using SWMM hydrology. The 2D timestep dictates the SWMM 1D timestep. Generally, this timestep is adequate for SWMM but in cases where the flows are contained in the 1D, the timestep may become too large for SWMM. This command forces it into the appropriate range. If this command is neglected, some models will experience very high mass errors. The range of timesteps used is reported in the SWMM .rpt file ('''TS03_5m_001_swmm.rpt''') in the '''TUFLOW\results''' folder.<br>

<li> Comment out the 'Map Cuttoff Depth' command by placing a '!' at the beginning of the line. This command is only necessary for 2D direct rainfall (rain on grid) modelling (SWMM Tutorial 2).<br>

*The 1D SWMM pipe urban pipe network junction attributes were updated to accomodate for the change in model configuration, from 2D direct rainfall to 1D SWMM hydrology.
*Check and result files associated with the SWMM hydrology modelling were inspected.
