The discrete gas cavity model is used in other transient analysis software and is described in various texts such as Thorley. It captures variable wavespeed phenomenon due to changing air pocket volume. It has been observed that models which exper...

Summary: Enable defining a calculation start time based on a time from start (can be > 24 hrs, e.g., T = 82 hrs), instead of a clock time (has to be 00 hrs to 23 hrs) (see attached figure). Model Setup Information: Our model has 7-day (168 hrs)...

Summary: There is an issue with the default hydraulic parameters when setting up a new calculation option, which can lead to erroneous fire flow results. The hydraulic parameter “Use Linear Interpolation for Multipoint Pumps?” should default to "T...

It would be helpful to have a global element symbology folder that allowed us to create a legend of Elements used in the model. You could also create a master table with nested Elements and/or Flex Table connection.

Add ESRI rest point service as found in MicroStation to stream proprietary high-res imagery

The functionality of rearranging entries individually is not present in: Selection Sets, FlexTables, Profiles, Queries, Scenarios (on the same level), Alternatives (on the same level) and probably a few that I'm missing. For some of these there is...

The selection of this head-loss ratio must result from a sensitivity analysis of the maximum piezometric level at the tank connection during the transient regime, as a function of the value of this coefficient.”

Introduce a Save-As Functionality on WaterGEMS for ArcGIS Pro, to allow the users to create a copy of the model and maintain all customization (layers, symbology, labels) in the original aprx.

When you create a profile, the default lines are thin and hard to see. If you make them thicker, it can look great. But you cannot save these changes as a default, AND (my favorite part) if you change the profile time step or play the profile the ...

In our system we have hundreds of physical customer meters that report hourly pressure. I have these in the model as SCADA elements and they are very useful but... the SCADA elements can only be associated with a junction somewhere else, so the el...
