Suggestion for Entering Population DWF Data at a Node

I (and a few others) think a welcome change to the DWF dialog in SWMM 5 would be the addition of another scale factor to modify the average flow field. The purpose of the scale factor would be to allow the users to enter the DWF contributing population * the various DWF patterns * the scale factor (in units of cfs/person or l/s/person) in the Inflows dialog. Some users of SWMM 5 prefer to use population directly in the GUI rather than doing this calculation externally and entering either the flow in cfs or l/s. An example of why this would be useful is a future conditions model in which the population either increases or decreases in the catchment.

Here's a revised emoji-laden table reflecting your suggestion for a welcome change in the Dry Weather Flow (DWF) dialog in SWMM 5, along with its implementation in InfoSWMM and ICM SWMM:

Topic 📘	SWMM5 🌊	InfoSWMM 🔄	ICM SWMM 🌪️	Emoji Illustration 🎨
Proposed DWF Scale Factor 🎚️	Addition of a scale factor to modify the average flow field, allowing users to input DWF contributing population, DWF patterns, and scale factor (in units of cfs/person or l/s/person) directly in the Inflows dialog.	(Potential implementation or extension in InfoSWMM based on user preference)	(Potential implementation or extension in ICM SWMM based on user preference)	🎚️👥💧
Usage Ease 🤗	Enabling direct population input in the GUI, eliminating the need for external calculations, thereby facilitating more straightforward flow entries in cfs or l/s.	(Assumed similar ease of use enhancement in InfoSWMM if implemented)	(Assumed similar ease of use enhancement in ICM SWMM if implemented)	🤗➡️💻
Future Conditions Modeling 🌐	Catering to models depicting population increase or decrease in a catchment, aiding in more accurate future condition analyses.	(Potential facilitation of future conditions modeling in InfoSWMM if implemented)	(Potential facilitation of future conditions modeling in ICM SWMM if implemented)	🌐👥🔄

This table encapsulates the proposed change in SWMM 5 concerning the Dry Weather Flow (DWF) dialog, allowing for a new scale factor to alter the average flow field. The table also leaves room for similar implementations or extensions in InfoSWMM and ICM SWMM, provided that these platforms decide to adopt this user-friendly feature, making it easier to handle population-based flow calculations directly within the software's GUI.
