RE: How should I approach this?
Jesse Dringoli
Hello Huy, You mentioned that this is for a "unidirectional flow" project - are you referring to a unidirectional flushing simulation, in which one or more hydrants are opened along with closure of one or more valves? Your questions seem to be about…

RE: How should I approach this?
Sushma Choure
Hello Yoko, Yes,, you can have separate customer elements for these two purposes of indoor use and irrigation use, which will connect to the same junction meaning adding demands to one junction only. About billing ID, two customer meters can have…

RE: Emitter Coefficient for flushing
Tom Walski
1. K is the overall emitter coefficient for the model element. k is an intermediate value used along the way. See page 451 in Advanced Water Distribution Modeling and Management for an explanation. Neither is "more accurate". K is what you enter into…

WaterGEMS Model for Unidirectional Flushing analysis: If the demand data is allocated by importing Customer Meter Element, would it interfere with flushing analysis?
Yoko
We are using WaterGEMS V8i SELECT Series 6. We are in the process of building a model for unidirectional flushing. For the model, we are planning to import the demand data using Customer Meter Element. Have there been any interference of Customer…

RE: What does the 'depth' in a Catchment Basin mean in SewerCAD and why it is different from the hydraulic grade ?
Craig Calvin
Hi Yoko, (edited) The properties dialog describes the wet well field "Depth (Node)" as " the calculated depth of flow measured from the node invert elevation" . Here's how the field is calculated. If the wet well's "Elevation (Initial)" is less…

RE: What does the 'depth' in a Catchment Basin mean in SewerCAD and why it is different from the hydraulic grade ?
Craig Calvin
If the latest patch set (dated May 25th, 2016 or later) is applied, the Depth (Node) will no longer use the upstream pipe's hydraulic grade. This behavior is also documented in the following article. How is the wet well Depth (Node) field calculated…

RE: How to convert a manhole into a bend in SewerCAD?
Jesse Dringoli
SewerCAD (and StormCAD) calculates hydraulic grade on a pipe-by-pipe basis using gradually varied flow equations. It is solves as a network with a backwater or frontwater approach, so that the HGL from one pipe typically crosses continuously over to the…

RE: How to convert a manhole into a bend in SewerCAD?
Jesse Dringoli
You could use the Batch Morph tool (Tools menu) to morph a selection set of these manholes into transitions, though you will need to enter the Top Elevation afterwards. You may want to take a look at your source shapefile. Each segment may be a separate…

RE: How to convert a manhole into a bend in SewerCAD?
Tom Walski
To put in bends, hold down the CTRL key when you left click. If these extra manholes exist, you can trace over them with a new pipe and then delete the incorrect representation.

RE: WaterGEM the System Head is lower than the pump curve settings
Tom Walski
We offer some tools to help you visualize what is happening in your system. Usually, the problem lies with a tank level on the discharge side of the pump. Try drawing a profile (View > Profile) and follow the hydraulic grade lien from a tank on the…

RE: WaterGEM the System Head is lower than the pump curve settings
Scott Kampa
Hello Yoko, This warning message usually indicates that the pump is operating beyond the user-entered pump characteristic curve (pump definition). This will happen when the pump definition is not defined all the way out to zero head. WaterCAD and WaterGEMS…

RE: Color coding is not showing up when the same file is opened in WaterGEM for AutoCAD
MPachlhofer
Yoko, I think I understand now. What you're saying is that the color codings are not showing up in your model even though you have them set up, correct? If that is the case here's what you can try. On the WaterCAD/GEMS menu go to Tools > Database Utilities…

Hi Yoko, The junction symbols aren't shown in you screen capture (if you want those to be shown, you can try adjusting your Drawing Scale/Symbol Size Multiplier). If you want the text to be colored, try this setting (Tools > Options). "[x] Color…

RE: Unexpected High Flow - WaterGEM
Scott Kampa
Hello Yoko, I assume the scenario that you are running is "1-Stead State Analysis". This appears to have a demand of 2.36 gpm and a tank level of 1397 ft. If you are looking at a different scenario, please let me know. When I compute the model as…
