• Will OpenFlow be able to simulate the case that the water from riverain flooding in the 2D grid is drained away through the sewer system?

    I'm just starting to learn how to use OpenFlows. I've noticed that OpenFlows can handle the overflow from a 1D sewer system and allow the water to flow over the 2D grid. I'm curious if OpenFlows can also work in the reverse process. And how to realize…
  • How to batch merge nodes in WaterCAD 10.03.01.08

    My WaterCAD version has a specific limit of 10,000 pipes for computing a scenario. I currently have 10,966 pipes. Due to the nature of the GIS model that was imported in the model builder, many of these same diameter pipes were made up of multiple polylines…
  • Hello! What is the best way to assess storage in SewerGEMS, accounting for pipes, manholes and wet wells?

    I am trying to determine the total storage available in the network in case of pump failure / shutdown at peak dry weather flow before overflowing from lowest point in the network. My model is currently set-up with Implicit Solver and there are multiple…
  • STORMCAD

    I'm trying to model a connection of pipes that has a Ductile Iron Pipe 12'' diameter (20M LENGTH) connected to a Increaser to connect a 20'' diameter pipe(4.97 M LENGTH) that is conected to a reducer for a connection of a 16'' diameter pipe. How can i…
  • How to split crossing pipes in bulk?

    While building the model many pipes are crossing each other and I need to split them at the crossing point using junctions.
  • Pipe lines are not build by using shapefiles in WaterGems

    I have shapefiles for the model, When opened in GIS the whole model is available, and when tried building the model with shapefiles in model builder pipelines is missing. Can anyone guide me through it? I would be glad.
  • How to assign valves to pipes AT NEAREST POINT

    I am a new user to WaterGEMS, and I am trying to build a system from scratch. I have figured out a number of shortcuts, but this one is per plexing to me. When the program assigns valves to the nearest pipe, it assigns them at the midpoint of the…
  • hide pipe labels in WaterCAD

    I've built a model that has a lot of pipes and hydrants so when I zoom out the pipe labels overlap the hydrants and make it impossible to see the hydrant labels. I tried turning them off by going to Tools>Options then to the "Labeling" tab and unchecking…
  • Re: EPAnet modeling

    Sounds like you are going through some of the usual teething troubles people have when they start to do hydraulic modeling. We should be able to help you out there, but first a couple of questions about your overall design: 1. If you close the pipeline…
  • Culvert Failure Analysis -- Which Program?

    I am looking to model a 72-inch CMP storm drain failure due to excessive thrust I suspect. I want to simulate the pipe failure, sink hole formation, the water surfacing, and the subsequent scouring. It's a bit of a tall order and will require substantial…
  • Re: Networks coordination

    Hi Amine, Bentley has a number of software tools that can help with this task. Our Civil products like InRoads, GEOPAK and PowerCivil allow you to lay out pipe networks (and other services) and then detect clashes. Each tool is slightly different…
  • Water modeling - flows passing through a closed pipe

    I am attempting to model a connection an existing distribution system. The goal is to supply two houses with drinking water and fill tanks for fire flows. What I have done is brought the water to the housing complex, then one line proceeds to the houses…
  • Darwin Calibrator Inactive Elements

    I'm fairly new to the software and have been going through the on demand courses. I have a decent understanding of how Darwin Calibrator works but I'm struggling with one thing. I have numerous inactive pipes in my model. Typically these are either…
  • Head Losses

    How can we calculate the energy consumed by the pump in Kilo Watts to over come the head losses in the pipes? Can energy losses be represented in Kilowatts if so how is the methadology? Please help me ASAP with this. I'm on the verge of completion of…
  • Re: Pipes in water cad v 8i

    Thank you for the instruction. I created the same in my project . I need to provide a vertical pipe to the top of the building. So i created junction J 6 at the ground level elevation and another junction J 7 at top of the building. Now I need to actually…
  • Re: Maximum number of pipes

    Generally our products also prevent saving of changes if you exceed the pipe limit. In other words you can't create a 10,000 pipe model using a 10 pipe WaterCAD license and then just export to EPANET to compute it. If you are not sure how many…
  • Colour Coding Pipe Pressure in Watergems

    I am trying to create a colour coding in watergems. Similar to assigning diameter, velocity and flow colour codings to pipe elements, I would like to do the same indicating pipe pressure. I know that I can use a colour codings on nodes to do this but…

    I'm getting some unusual results and am unable to find a solution. I'm trying to better calibrate our model near an area where 2 pressure zones meet. I've performed a fire flow analysis and tried to confirm the pressures and flow in that area. A flow…
  • How to know if pipes are connected or not by a node?

    I have transfered a drawing from AutoCAD to WaterCAD V8i and I see the pipes and also de nodes. The problem is that although I see nodes in some pipes that either cross other pipes or that stop (connect) to other pipes, but I'm not sure if there is connectivity…

  • Pump reports 0 gpm.. need a fix

    Hello, I've inherited a water system file and am trying to figure out the cause for a bunch of low pressure junctions. There is a pump nearby that reports 0 gpm, so it's obviously not helping my system. I can't figure out why there is no flow between…
