    I've been asking for that sort of functionality in ICM for some time, but it hasn't happened so far!

    Thanks, Patrick, much appreciated. The forum has been really useful and I've enjoyed being part of the Innovyze scene ever since the WASSP days, it's been enormously exciting and rewarding. All the...

    Goodbye

    I'm retiring on 21st December. I'd just like to thanks you all for stimulating questions and helpful answers over the years.
    I've had a great career and really enjoyed it all. I hope you will all...

    My first question would be: why are you trying to do it that way? Why not represent the downstream channel explicitly as a river reach, at least over the length where flows bypassing the culvert...

    Dinesh - RTC is a standard feature, even if it is tricky at times. There is a full account in help, and the tutorials. It's not up to me, or this forum, to do basic training for you. That's you or...

    You need to use an RTC (Real Time Control). Look in Help. They can be tricky but this one sounds quite simple. You may need to introduce a dummy sluice upstream of the pumping station, that shuts...

    That's so that it ends up looking like a WASSP model? Nostalgia trip!

    I don't know of a direct way, but I suppose you could make a copy of a flow survey and then paste your data into it.

    I hope an InfoSWMM user can be more help.

    You should not be using weirs. I don't now InfoSWMM, I'm an ICM user, but I expect they have similar functionality. In ICM, I would use the "force main" model for the pipework. But is it even...

    In ICM, applying a constant level of 20ft above the level of the outfall to the outfall node would do that. I imagine InfoSWMM is similar. That should take care of the initialisation issue too.

    Dummy orifice with limiting discharge. That's the easy bit. The harder bit is why, and how does this represent reality?

    "Bad allocation" is one of those random messages ICM is good at! It happens on odd occasions, not just DTM-related. It means some sort of memory error has occurred and it can't access the ground...

    That is what you need to do, then. Model- model parameters - simulation parameters - top two lines. Help is very clear on how this works. Try reducing one at a time until you get the results you...

    Have you changed both minimum base flow and base flow factor in simulation parameters?

    The "store results in DWF" is important if you're running TSRs, which it sounds like you are. There's always cut and paste to merge results if you need to. Remember to fill in missing timesteps with...

    Yes, a user defined pollutant. Easy enough, no diurnal variation. About 35 g/l, I think.

    If the water is lost from the system and you have a good idea of the head required, that's a simple solution. Alternatively, you could set a head-discharge relationship for a Gully2D node if that's...

    You're right, that should work fine. The river reach node you connect to should be a break node, not a manhole.

    I was thinking more of visual observations, flood extents and so on. Monitors would be at high risk and the data would probably be highly erratic.
    That's an interesting blog, excellent for...

    Sounds like an interesting PhD, Duncan. Either way, we're into made up numbers territory, which means ideally "calibrating" them form observed performance if possible or doing some sensitivity...

    No formal guidance that I know of. I'd go for a screen with some plausible made-up numbers for bar (trunk) diameter and spacing. If it matters a lot about the possibility of the dam being dislodged,...

    You don't HAVE to use a variable speed pump in the model just because that's what will be used in reality.
