Bill, I just confirmed that the process in the wiki article that I linked to in my reply yesterday will allow WaterCAD/GEMS to integrate with Power GEOPAK, so it should also work for Power Inroads. I'd suggest using the optional step 4 to create an icon on your desktop that automatically loads WaterGEMS for you. It makes things much easier. Regards, Mark

Forum Post: RE: How to assign load at manhole by using thiessen polygon in SewerGEMS for Arcmap directly
Rohit, 1) The Thiessen method is just one method for generating service areas for nodes, and is calculated automatically by the tool. If you would like to manually draw your service area polygons, you'll need to do that in an external application such as ArcGIS and generate a shapefile, which can be used in Loadbuilder for the Service Area Layer. The key is that there needs to be a field in the polygon shapefile that links to the element ID of the nodes (manholes) in the model. You can also generate service areas with the Thiessen method, then open the shapefile in another program like ArcGIS and modify the geometry of the polygons. 2) As mentioned in a similar thread yesterday, Loadbuilder imports loads as Base+Pattern. If you need to use Unit Loads, see the below article: Using Unit Loads and Extreme Flow Factors after a LoadBuilder run Here is another article worth considering: Import loads from shapefile containing polygons with land use type and total population

Wiki Page: Pressure pipe vs. conduit between pump and wetwell
Applies To Product(s): Bentley SewerGEMS, CivilStorm Version(s): 08.11.XX.XX Environment: N/A Area: Modeling Subarea: Original Author: Jesse Dringoli, Bentley Technical Support Group Problem When using the Implicit dynamic solver, I can use a conduit between a wetwell and a pump. With the GVF Convex solver, I'm forced to use a pressure pipe in this case. Why? Solution This is mainly a technical limitation due to the numerical solvers running behind the scenes. The GVF Convex (SewerCAD) solver calculates pressure networks separately using the EPANET engine where all pipes are assumed to be full, so a pressure pipe is expected. With the implicit dynamic solver, all parts of the network (both pressure and open flow/gravity) are solved at the same time, by the same solver. The Preissmann slot method is used to simulate pressurized flow in both pressure pipes and conduits. For compatibility between solvers, it may be best to use pressure pipes. Both conduits and pressure pipes can be designated as "virtual" as well (no hydraulic significance - flow in=flow out) for cases such as submersible pumps.

OR How does the implicit solver (SewerGEMS) transition from pressure flow to gravity flow and vice versa? Product: SewerGEMS V8i Version: 08.11.02.75 Area: Modeling, Problem ID#: 67974, PROBLEMSOLVING Solution This message is generated anytime pressure pipe or conduit HGL is above the pressure pipe or conduit top elevation. The SewerGEMS calculation engine does not distinguish between conduits and pressure pipes in the model, so this message is generated when pressure pipes exist in the system. You can view profiles of the system to see the HGL across the system, as a way to see any gravity pipes in the model are surcharging. For more information on Preissmann slot method, there are topics about this in the SewerGEMS Help documentation. Simply search for the term "Preissmann slot" or "Pressurized Flow".

Forum Post: HGL lower for larger rainfall event in CivilStorm
I have a Civil Storm stormwater outfall model setup to run the Implicit Dynamic Wave Solver. My areas are entered in with SCS CN data and my rainfall is entered as time-depth. I am running the 10-, 25-, 50-, and 100-year storm through the system and the main goal is to get a flood elevation at a low point in the system. There is an HGL increase in the HGL at the low point between the 10- and 25-year storm but not from the 25- to 50- or 100-year storm events. In fact the HGL actually decreases from 25- to 50- and from 50- to 100- The model volumes, volumes loss, continuity errors (0.2% max), and all of the other outputs for the individual scenarios seem to make sense. There is a diversion in the system where the main outfall splits, which this solver ignores but felt like I should at least mention it. The lowest two structures in the system are part of a tributary system and not the main outfall. These are the only structures in this part of the model that the HGl exceeds the rim elevation for the 10- and 25-year storms. In the 50- and 100-year storms there is another structure in the system that over tops. All of the structures that overtop have stage-storage ponding area above the rim as well. I am wondering if the structure in the main outfall that is overtopping in the bigger storms is giving me the issues that I am seeing in the model. I have double checked all of the background data and I don't see anything that looks wrong but I am not 100% sure what could be causing this. I also have a peak flow model in a separate file with the same system and it seems to be working and giving "logical" results. (I.e. the HGL increases with the increased rainfall). This is about the best I can describe the model and issues I am having. Any help would be greatly appreciated. I almost feel like it is something simple but I have exhausted everything I know to look for. Thanks in advance, James E.

Wiki Page: Should the EPANET solver and the WaterGEMS/CAD solver give the same results for a model?
Applies To Product(s): Bentley WaterGEMS, Bentley HAMMER, Bentley WaterCAD Version(s): 08.11.XX.XX Environment: N/A Area: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem Should the EPANET solver 2.00.12 (2.00.10) and the WaterGEMS/CAD solver 2.00.12 (2.00.10) give the same results for a model? Which solver is more accurate? Solution The WaterGEMS and WaterCAD’s default numerical solver has many improvements above and beyond the core EPANET solver used to calculate hydraulics. Therefore, small differences in results are expected when comparing WaterGEMS or WaterCAD results to results in the EPANET program. To assist in cases where a user may want to solve hydraulics without these improvements, the “Engine Compatibility” calculation option can be used. For example, if you’re comparing results from the 2.00.12 version of the EPANET program, you would select EPANET 2.00.12 in the Engine Compatibility from the dropdown for the engine compatibility option. This will allow WaterGEMS or WaterCAD to solve the hydraulics with the same solver used in the EPANET 2.00.12 program itself. By default, the Engine Compatibility mode will be set to “WaterGEMS 2.00.12” for new projects, which contains the aforementioned improvements beyond the base EPANET 2.0.12 numerical solver. The details of these improvements are outlined in the Help Topic “Engine Compatibility Calculation Option” that comes with the WaterGEMS and WaterCAD software. When importing an EPANET INP file, however, the Engine Compatibility will be set to EPANET 2.012, for best compatibility. Also, note that when comparing a particular timestep during an EPS, results could be even more sensitive to the calculation option. For example, if you have an unstable valve or control arrangement, the small differences in the solvers might result in a control or valve status change happening at a slightly different timestep. So large result differences for a given timestep between the two solvers could simply be due to a small delay in element status change, such as a pump being on in one case and off in the other. The status may switch back in the very next timestep, so the overall big picture results may need to be considered instead of just a single timestep, especially in models with problematic or sensitive controls, pumps or valves. In short, if you’re looking to get results comparable to the EPANET program, be sure to set the Engine Compatibility mode to EPANET. Saying which results are more or less accurate is nearly impossible to determine. The solvers used are slightly different and those slight differences can cause slightly different results to occur as you've seen. The model is not going to give you perfectly matching results to what you're seeing in the field no matter what solver you use, but either solver should be within some acceptable margin of error that is accurate enough to use it for predictions of what will happen given a certain change or given condition in your system. The output is really only as good as the input though, so if you have bad data your results are going to reflect that. Also, keep in mind that all the solvers are based on mathematical algorithms that have long been used to solve network hydraulics, so they are probably all going to give similar results. The only way you can truly know the accuracy of your model is when you have it calibrated against your field data and measure the error of deviation based on that. It really comes down to, which solver that you're comfortable using or that your client would like to use, and that is why we offer both solvers with the WaterGEMS/WaterCAD/HAMMER software. See Also What are the limitations of importing/exporting an EPANET file?

Wiki Page: How to multiply runoff hydrograph flow by a certain factor
Applies To Product(s): Bentley SewerGEMS, Bentley CivilStorm, Bentley PondPack, Bentley SewerCAD Version(s): 08.11.XX.XX Environment: N/A Area: Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem How do I take my current hydrograph results and multiply them by a certain factor (such as 1.5) and recompute my model? Solution 1) Run the model and right click on each catchment to generate the hydrograph of flow vs. time. 2) Copy just the flow data from the data tab and close that window. 3) In the catchment properties set the 'Runoff Method' to "User Defined Hydrograph". 4) Click the drop down arrow to the right of where it says for the Hydrograph property and choose 5) Create a new hydrograph and fill in the information for start time, increment (this should be the same time increment you have set in the calculation options and is the same increment your current hydrograph uses), and end time. 6) Paste in the flow data from the original hydrograph 7) Right click on the Flow column header and choose "global edit" to multiply it by the desired factor, such as 1.5 8) Set the user defined hydrograph to in the properties of that catchment 9) Repeat for other catchments Alternatively you could adjust your storm rainfall information accordingly to simulate a higher or lower frequency storm. Note: The ability to globally increase or decrease wet weather loading for an extended period simulation by a factor is not natively possible since it's not a typical workflow for users. To globally adjust wet weather loading, it is recommended to apply a more severe storm event.

Forum Post: RE: HGL lower for larger rainfall event in CivilStorm
James, Regarding the "HGL" that you're comparing between storm events; is this the max HGL? If it's the HGL that you see right after running the model, you're likely looking at the time zero results. Be sure to graph the element (you can do this for multiple scenarios) or look at the "Max" result field. If this doesn't help, it would be useful to provide your CivilStorm version along with a copy of your model files (.STSW and .STSW.SQLITE, zipped, if using the latest version) and the locations/labels of interest. There are two options for sharing your model files on Communities. If you would like the files to be visible to other members, compress the files into a zip file and upload them as an attachment using the ‘Advanced Reply editor’ before posting.
