Stormwater Drainage Subcatchment characteristic width & Slope

Greetings,

We are working on Urban drainage design using SewerGEMS latest version of 10.03.04.53 with Explicit solver & EPASWMM runoff method.
In which the catchment characteristic width & slope are inputs to the model (shown in below screenshot). Is there any possibility to calculate the Catchment characteristic width & slope in SewerGEMS.
Could you please explain about these inputs and how it facilitates the runoff flow & volume.

Regards
Ganesh Bala S
