• Creating Double Broken Pipes in ORD

    Is there an easy way to model double broken pipes into openroads? I'm looking to draw an underdrain below a ditch berm. It seems like a lot of the modeling of pipes is done with top down with station and elevation. But having to put bends in pipes…
  • ORD drainage - changing size of bottom drainage structure (FDOT)

    Hello, I am working on creating an existing drainage model. i drew an existing manhole and connected some 48" pipes to it. But the pipes are now way to big for that manhole structure. I want to make the bottom structure of the manhole bigger. …
  • Geopak Drainage Error Computing output for a network with Pipe-Arch

    I am trying to design a storm drain network in an area with limited cover. When I try to use the "Pipe-Arch" option, Geopak reports an error. The same network runs just fine when using circular pipe or box culvert or elliptical pipe. I checked the drainage…
  • within Storm and Sanitary, I am finding that the pipe velocity does not match my calculations.

    The program is saying that the flow is subcritical. while my calculation show that it should be super critical. The variables are thus: D= 1.5'; Longitudinal slope= 1.00%; Roughness = 0.0130; flow rate = 0.479 cfs The program gives a Froude Number…
  • How can I generate a travel time within my pipes?

    I want the program to show the travel time within a pipe and to show the total travel time and where that occurs. How can I do that?
  • Geopak Drainage - Friction Slope

    Has anyone had any issues with Geopak Drainage calculating the friction slopes wrong? I have contacted Bently support and spoke with a couple of their engineers, sent them all my data , and they could not seem to figure it out. I even created a spreadsheet…
