Model a sag inlet with an allowable depth of ponding
I need to be able to model a sag inlet accurately within InfoDrainage. I would like to design these inlets so that there is an allowable ponding depth, and then any volume that exceeds that depth is applied to the surface as a 2D overland flow.

Updating an Existing C3D Drainage Network When Importing Back
As a workflow we start our design in C3D then export for analysis in Infodrainage, We then bring back to C3D the amended network, but it is a new network, and so all the formatting that was initially done on it is lost.
C3D should update the network with the amended information from Infodrainage, including HGL, pit rotation etc.2 votesThank you for submitting and voting for this idea.

SuDS and Inlet Level sync stepdowns
Infodrainage 2023.2
Inlets into SuDS features need to be able to be different from the SuDS features bed level.
It is almost always necessary to have a step down between inlets and outlets on Ponds and Swales etc.2 votesThank you for the suggestion and thanks to those who commented and voted.
The inlet pipe will always try to sync to the bed level of your Storm Water Control (SWC), however, you can easily lock the pipe and manipulate the level so your inlet pipe can be higher and your outlet pipe can be lower. You can introduce inlet and outlet chambers and you will have full flexibility in dropping the levels as required.
Does the above address the issue?

Better Level Coordination of Swales
InfoDrainage 2023.2
If you have a swale with several branches discharging into it the invert level of those branches is fixed at the swales outlet invert level and not at the bed level corresponding to its position along the swale.1 voteThank you for the suggestion and thanks to those who commented and voted.
We agree that in scenarios where multiple pipes are discharging into a steep swale at various points, the bed level might not be the best level to sync to. This has been discussed and it's been agreed that we will interpolate the right level using the centre line and sync the connection to it. This is now in the road map for future implementation.

Automatic M5-60 and R values based on Location
Most models are built on surveys that are on National Grid Coordinates. It would therefore be good for the rainfall data to automatically generate M5-60 and R values based on NGC for the site with the option to click Map and reposition if necessary.

FSR is an outdated rainfall method which was developed in the 1970s, this is why various LLFAs around the UK are now rejecting drainage statements submissions when FSR was used as a rainfall. This is one of the reasons why we would be hesitant to invest into investing more time into this. We are currently working on FEH22 implementation which will be made available to UK customers in future releases of the software.
However, FSR has a 1km2 resolution, therefore, you can still get the exact site accuratley by hoovering over the map and keeping an eye on the coordinates on the top-left corner (see screenshot). Take one coordinate from your site and use the first three digits from the easting and the first three digits from the northing to establish the exact location on the FSR…

Results format
Why does InfoDrainage deafult to showing you the Stormwater Controls summary, and only the Stormwater Controls summary, when a model finishes running?
This occurs even if the Stormwater Controls are fine but the Junctions are showing flooding.
I mean, I know you can manually check all the other results summaries, but why doesn't InfoDrainage either open them all or choose the most critical one?
2 votesThank you for the suggestion and thanks to those who commented and voted. This is to confirm that we've received and reviewed your suggestion and here is our response:
We believe that stormwater controls are the most critical element of the drainage design. Hence we show the results of SWCs as soon as the simulation is finalised.
Users can/should check the rest of the model to ensure that there aren't any bottlenecks in the system.
It might be feasible to implement a dropdown menu within the SWC results so we can still show results from SWCs, but we make it easier for users to jump to different screens and check the inflows, connections and junctions.
Would the above address what is required for this case?

Realistic ground profile for swales
This is a flaw that's been going since MicroDrainage, but when you change the type of a connection from a pipe to an open channel, like a swale, there's no information at all provided about the actual size of that feature.
I had one come in the other day, only attenuation on the whole site was in a swale. Parameters for the swale has been set 0.5m base width, 1:3 side slopes, Mannings n 0.03, everything normal and okay with this, right?
But the manholes at the top and bottom of the link that had been turned into the swale…
2 votesThank you for the suggestion and thanks to those who commented and voted.
If you try to build your swales using the SWCs rather than converting links to swales, you will see that you can start from the top area and go down (1:3) or you can start from the bottom and go up (1:3).
Does the above address your suggestion? I'd be interested to hear your thoughts once you try it.

Perforated pipes
This will be hard to implement so it's kind of a longer term ambition, but it would be really helpful if InfoDrainage could properly model a perforated pipe.
Pretty often we have a perforated pipe below a structure - what would now be called a stormwater control - like a permeable car park or a swale. The "main" flow is running through the pipe, usually because depth won't permit it to be sent directly into a shallow feature, but as the hydraulic head rises water infiltrates out of the pipe in a gravel trench and builds up until it fills…
2 votesThank you for the suggestion and thanks to those who commented and voted.
Within SWCs, we have added an option called Under Drain, with this option, you can model a perforated pipe, and once the pipe is out of the system into the flow control chamber, it won't be perforated anymore so you can use a conventional pipe to model it.
Please feel free to touch base with our support team if you have any questions on the above.
Does the above address your suggestion?

Output flow controls details
When presenting results to be checked/reviewed either internally or by client or LPA/LLFA, you have to present details of orifices, hydrobrakes, etc so that they can understand what items are in there. In InfoDrainage because flow controls are not a seperate item type, the only way to present that information is to output every single "outlet" on the scheme.
On a large scheme, that means that my results file can be three or four pages of dozens of lines of "outlet = pipe", and about two or three actually relevant items hidden somewhere in the middle.
It would be great…

Output Cv values
Cv values used to be set globally and would be output as part of the simulation criteria, so the values that were used were always visible in results files for LPA/LLFA officers to check that the model complied if a 0.9 or 0.95 Cv was requested as many authorities now do.
Now the Cv values are per catchment, so if I need to change them to suit an authority's requirements I have to do it manually on many items, and it's hard to output them to prove to the authority that I have followed their requirements.
It would be great…
2 votesThe report that is automatically generated by InfoDrainage has this detail when you tick Inflows (see screenshot attached). InfoDrainage will report on every subcatchment and detail what CV values have been used for summer and winter.

Levels for "junction" items
When using the "junction" connection item, it always sets the cover level on the item to 0. This is true even if you had a manhole that had a proper cover and invert level input, if you switch the manhole to a junction (for instance because you don't want to falsely include the volume of a manhole that isn't actually there) then it jumps the cover to 0 and the invert to -1.5. (It might not do it if you have a ground model in, not sure, I usually work without).
You can fix it by going across to the…

In InfoDrainage, junctions are used as nodes without volume to enable modelling a Y or T junction, or it could be a point in the middle of a culvert that is getting wider for some reason.
You are right; when the pipe US and DS cover levels are 0, and the junction has a level of 0, the model will find no way to design the system and run the design wizard. Therefore, to address this, we've implemented a warning message that will stop users from proceeding with the design if they have junctions and the associated ends of the pipe have a 0 level (that hasn't been overwritten). Users can still use the level 0 but they need to overwrite the default 0 to proceed. The warning message will be made available to users in a…
