• Implicit Solver - Channel flooding

    Hello, I'm simulating a open channel network in sewergems using Implicit solver. In certain stretches, it shows the HGL is above the ground level and I was in the intention that it is flooding. Following is a sample figure. But the post in…

    Dears, A topic for discussion which was once raised but didn't seem to have concluded except for reference to use the most recent release of the software which may or may not be related to the causes... anyhow, the difference in this post is that we…

  • Raise in maximum hydraulic grade line (for about 2.0m) when cross-sections intervals are made finer. Why?

    Hi, Can you explain why the maximum hydraulic grade line is increasing when additional cross-sections are added and keeping all other parameters unchanged? In current drainage model comprising of open channels & culverts the maximum hydraulic grade…

  • SewerGems Hydraulic grade line in profile is not correct, also drastic change in HGL peak level along same segment.

    Hi All, I am using SewerGems (connect edition), I believe most users of the software might have encountered this issue. While working and checking the network profiles it is observed that, HGL (water level) shows drastic level change. In principle…

  • EGL OUT higher than EGL IN

    Steve Van Saun

    Hello, for some reason I am getting an EGL that drops down as you head upstream. I would expect the EGL to continue to climb as you move up the profile. The inflow at GI-3 is 0.95 cfs and the inflow at CB-4 is 1045 cfs, so not all that high. Also, the…

    Hi, I am a new user to WaterCad and I am trying to run a model which I have attached with this post. It runs fine but I see HGL to be constant in junction flex table. I would appreciate if someone could help me to know why it is calculated to be constant…

    Hi, I created small and simple system with pump at elevation 0.0' to push water up to outfall at elevation 15.0'. Highest pipe located in the middle between pump and the outfall is at elevation 35.0' (water from pump goes from el. 0' to el. 35' and…

    Kim Davis
    If the junctions are gravity fed, Tom's suggestions are still good but you need to change hte wording a bit. If the pressures are always negative, no matter what the demand, then check the HGL of the tank that feeds the zone, and check the elevation…
