1- In the model attached, the User Notifications says " CO-4 has adverse slope" however when I look to the profile does not show that, and the link properties does show the valuse = 1.526 mm/m? 2- the Profile from MH31 to LS-33 shows flooding, however; when I check Manholes (MH31 and MH32) properties " is Ever Overflowing? it shows False. would you please clarify?

Forum Post: RE: Overflowing and Flooding Section
Hello Videet, For flood modeling you will need to use OpenFlows FLOOD integrated with a CivilStorm network model. A StormCAD model cannot be used because it solves the model with GVF equations (Gradually Varied Flow), when a Saint-Venant equation model is needed. SewerGEMS and CivilStorm does it. For this type of study you will need the following information: digital surface model, surface´s permeability and roughness data, CivilStorm model with sanitary loads (as inflows), storm data (precipitation or intensity curve). We have an page with some interesting learning content (videos and guides) about urban flood modeling in this page that I would like to share with you for complimentary information. Hope this information helps. regards, Douglas Miranda.

Forum Post: RE: Overflowing and Flooding Section
Thank Douglas! It seems like I need to model the network with sanitary + storm data in CivilStorm or SewerGEMS, and later take it to OpenFlows Flood. Right? My next question is, can i get the depth of overflowing/flooding conditions using OpenFlows Flood? Or will I get only the area (spread) of flooding/overflowing sections?

Forum Post: RE: Overflowing and Flooding Section
Hi, If you are modeling the storm loads with predefined flows/hydrographs, yes, you will need to model it together with sanitary loads in CivilStorm or SewerGEMS, and then integrate this model into OpenFlows FLOOD. If you are modeling the storm loads with catchment areas connected to catch basins /inlets, you can model it into OpenFlows FLOOD, adding the storm event curve and letting the 2D runoff calculation to calculate the flow that enters into the network. So in this case you will need to have the CivilStorm just with the sanitary loads. After finishing the simulation with OpenFlows FLOOD, you can see the depth of flooding, spread area, velocity and flow with graphs, color coded maps and profiles. Below I share a video that illustrates it: Viewing Results on Maps and graphs This tutorial shows an example of a flood modeling that uses an existing CivilStorm/SewerGEMS model and applies OpenFlows FLOOD to calculate the stormwater that enters into the network. regards,

Forum Post: RE: Bing MAP Background
Hello, Bing map data is directly received from Microsoft, Bentley uses service provided by Microsoft to retrieve the images for a given area and then draw them on screen. However all the controls about, when to update the imagery's on what interval or when it was updated is on the Microsoft side. Also the images taken vary depending where you are.

Forum Post: RE: Bing MAP Background
To add to Sushma's reply - based on a few internet searches, you can see that Bing Maps images can sometimes be taken over a period of time and stitched together, hence there is no "updated" date shown. If Bing Maps does not have an adequately up-to-date image of your project area, you can insert an image file in the Background Layers manager. I have added a note about this in the following article from our Wiki: Using Bing Maps as a Background
↧
Wiki Page: Using Bing Maps as a Background
Product(s): WaterGEMS, WaterCAD, HAMMER, SewerGEMS, SewerCAD, StormCAD, CivilStorm Version(s): 10.01.XX.XX and greater Area: Layout and Data input Problem How can I view a Bing Map aerial or road map as a background for my hydraulic model? Solution Starting with the CONNECT Edition Update 1 release (10.01.XX.XX), Bing Maps can be added directly from the background layers manager (active internet connection required), with the ability to align to the model with up to three points of reference. See the related Help topic for more details. To check if you have the ability to use Bing Maps, go to File > Help > About (or, Help > About, for older versions). The version number shown in the lower-left corner needs to be 10.01.XX.XX or greater. For CONNECT Edition Update 2 and greater, you do not need to obtain a Bing Maps key from Microsoft and can utilize a special per-product Bentley key, as long as you are signed into the CONNECTION Client. For CONNECT Edition Update 1 , you will need a Microsoft account to generate a Bing Maps key - https://www.bingmapsportal.com/ . Starting with CONNECT Edition Update 2 , you can choose to use a built-in Bentley Bing Maps Key, or choose your own user-generated Bing Maps key as before. You would click the ellipsis (...) button in the upper right of the dialog shown above and will have the option to toggle between the two different keys. Term of Use - You can find the terms of use for Bing maps by clicking File > Help > About WaterGEMS, then clicking the Legal and Patent Notices button. You will find Microsoft Bing Terms of Use and Microsoft Bing Print Rights . Frequency of Updates - Bentley uses service provided by Microsoft to retrieve Bing Maps aerial images for a given area and then display them. Microsoft controls the frequency of when the images are updated. The date that the images were taken varies depending on your location. Data may be outdated in areas with recent development. Some images are taken over a period of time and stitched together later, hence an exact date is not shown. If Bing Maps does not have an adequately up-to-date image of your project area, you can insert an image file in the Background Layers manager . Alignment and Projection Regarding alignment and projection, the Bing Maps feature works off of web mercator projections, using the Map Alignment field. The Map Alignment can be used to help transform the background. However, this feature doesn't use a true State Plane-like reprojection like you might see in a program like MicroStation or ArcMap, where you can list what the projection is. To align the map with the model, select “3 control points” for the “Map alignment” dropdown in the Bing Maps Properties dialog. You can then select three points in your model and three corresponding points on the map, and the map will align itself to those points. For example if a particular junction is known to be at a particular road intersection, select that junction and the corresponding street intersection on the map. The map will be rotated and stretched to align with those three points. Troubleshooting Restricted internet access : If you have limited connection to the internet and cannot access sites which are not permitted by the administrator, you may need to request that an exception be added for Bing Maps. Otherwise, you may not be able to insert or view a Bing map background. The following address needs to be added to the exception list of your firewall or security settings, then you should be able to use Bing Map. dev.virtualearth.net Bing Map not displaying after reopening the model : In version 10.01. 00 .XX, if you uncheck the Bing Maps background layer, save and reopen the model, re-checking it will not correctly display the map and you will need to re-edit the Bing Maps definition. This issue is resolved in version 10.01. 01.04 (reference #788487) Note also that if a flushing report or plan view report does not display correctly with a Bing map active, this is addressed in a patch to version 10.01.01.04 (and will be fixed in future versions as well) - see: Blank Page in Report of Plan View or Flushing Report with Bing Map Active Video Demonstration https://youtu.be/Tn47UAqeMoo See Also How to add background aerial and road map images to your model

Forum Post: LID design only works in SewerCAD - not StormCAD?
From what I have read StormCAD is not linked to EPA-SWMM. I was going to attempt to design all of my system hydrology & hydraulics in one program, but I believe SewerCAD is the correct program to be using. Am I correct? Thank you, Debbie Tumler

Hi Mohamad, 1) I can see what you are saying and I suspect it may be due to the negative elevations. Please allow us some time to investigate further. Thank you for your patience. 2) I also see this, but the lack of overflow may be due to this . Again, we will investigate further and get back to you.

Hi Jesse, Thank you for the response. We have created a custom four quadrant curve which covers both the turbine and pumping quadrants, but based on your response I assume the turbine element cannot be run in reverse. Are there any plans in the future to add a reversible pump-turbine element to Hammer? Regards, Luke

Forum Post: Pumping flow- Using SWMM Solver In sewer gems connect Edition
Dears im now designing a storm drainage network ends with pumping station, and to reduce the capacity of the pumping mains i used a balancing tank to route the flow in it as the attached figure figure(1) shows pumping station configuration the system is attached to a 5 km force main with diameter of 1000 mm pumping a flow of 1200 l/sec. i noticed that the flow curve at the pipe just down stream the pump has a reverse flow (Negative) after adjusting both pumping head and on/off levels it returned to start from zero. but i don't trust the results at this point. there is another point, the reverse flow curve in the downstream pipe is different from the last pipe before the outlet point. i need to know the reason and how to solve this issue . figure (2) shows the reverse flow just downstream pumps figure (3) shows the flow curve at the pipe just before outlet point which varies from the flow curve downstream the pump.
