Storage area polygons
Storage nodes often represent detention basins or other locations with large areas. Pipes enter/leave from opposite sides. With the standard link/node configuration, one or more link will be mis-configured compared to the actual location.
I have long wanted to have a storage area polygon, with links connecting to the nearest edge, rather than the center.
6 votesGreat ideas! The goal is the simplify the physical location to either measured (as-built) or designed locations of pond outfalls, while either logically enforcing the relationship of outfalls to pond/outlet without forced links that do not represent physical pipes.

Auto populate an incremental ID for objects such as lines/polygons/subcatchments etc.
Often source data is provided with a non unique ID.
Nodes auto generate an ID, and conduits will create a node, but the remaining asset classes struggle somewhat and often you need to manipulate the GIS data.
I would like to be able to have ICM (and WS Pro for that matter) auto populate a unique ID (such as row ID).
There used to be a blog post written with a Ruby script to do this, but it appears to have been removed from the website. Alternately post the Ruby scripts again somewhere.
Thanks,

Add SWMM5 Ideal Pump to InfoWorks ICM
Does InfoWorks ICM have an equivalent to an ideal pump in SWMM which pumps whatever is entering the SPS out of the SPS?
It would be a good feature to include into infoworks as I needed to play around a bit to get it. I found I had to add line 2 or the pump kept on turning off rather than flow pacing.
I have seen a screw pump used previously to pump out what comes into the SPS but dependent upon the head discharge parameters this can back up the incoming sewer. If I set a curve similar to…

Correct calculation of volume within storage node when using porosity
Currently when a porosity value is applied to a storage node, the porosity is only applied for storage array entries which are below ground level. Storage array entries above ground level are assumed to have a porosity of 100%. Between the highest storage array level value below ground and the lowest storage array level value above ground the porosity is assumed to increase linearly between the value you applied and 100%. i.e. the storage is assumed to be conical.
This should be corrected. The porosity value applied should be applied to the whole storage array both above and below ground.…5 votesCould you provide a practical example of porosity above ground?

Structure flow mode reported in the results
Sometimes when evaluating results at structures we see strange results that require investigation; invariably we find out that this is because the flow mode has changed. (e.g. from free to drowned). It would be very helpful if the ICM results were able to report the flow mode as a time-varying output. This would result in a lot of time saving when investigating models. For reference I am referring to the Flow Mode functionality that is available in InfoWorks RS and Flood Modeller Pro.

Update user defined vortex controls in ICM so hydrobrake head discharge curves can be modelled
Current user defined vortex controls don't accept head discharge curves where the discharge reduces for increasing head i.e. what happens in a hydrobrake. It would be useful to get this updated to ensure consistency between ICM and drainage design.

Modelling of mud and other non-Newtonian flows
We've a lot of work at the moment modelling the failure of tailings dams. Tailings dams typically have material that acts in a non-Newtonian manner. To effectively model these sorts of fluids would require the inclusion of additional fluid properties. The Bingham method (https://en.wikipedia.org/wiki/Bingham_plastic) has been successfully applied in other applications.

Slot Width field for 1D conduits
Could the Slot Width field be enabled for Conduit Type "Conduit" and results generated by the application of the numerical correction tool been stored there for greater clarity, thanks.
4 votesThanks for the idea!
The slot width field is used to define the width of the drain when using a 2D conduit. Are you after a field to define preissmann slot?

odour
Air Phase Model Function - Can Innovyze consider to include air phase modelling function in InfoWorks? At moment, the odour modelling is done separately by various methods using the sewer hydraulic data as the input. As a result, the odour modelling has to be done by different teams and often costing. There is a strong market demand to integrate the liquid and air phase modelling, for example DHI already has a function. It is technically challenging to have a full integration, however there are well developed simplified ways to achieve that.

Simple means to set initial storage area water surface elevations
Please incorporate a system for setting initial water surface elevations in storage nodes that works as easily as the process is in XPSWMM or HEC-RAS. The program should hold this water level during warm-up stabilization.

As a user i want to see 'failed' simulations within the Results Management Window rather than 'completed' status
When a sim completes as status Incomplete the sim icon changes to red and the Job control window states sim status Incomplete. However, in the Results Management window the sim status is ‘Complete’!
For consistency and user friendliness; Please can you fix to reflect the status Incomplete? This change will make re-running sims so much easier and save end users not having to delve into IDs to work out which sim need investigation.

ICM - HEC-22 Combination Inlet for continuous grade inlets
Currently ICM has 6 FWHA Gully Inlet types:
ContCo Continuous Curb Opening
ContG Continuous Grate
SagC Sag Combination
SagCO Sag Curb Opening
SagG Sag Grate and
UPC GrateA commonly used Inlet type (particularly in QLD Australia) that is missing from this list is the combination (curb opening + grate) on a continuous grade.
Section 4.4.4.4. in the HEC-22 manual discuss the capacity of these inlets where the curb opening precedes the grate in the direction of flow. It would be particularly useful to include this option in ICM rather than assuming a grate only inlet type or having to…

Revision to manhole representation
ICM's default representation of manholes could be more accurate. The limitations of current setup allows accurate representation of either the shaft or the benching but not both. Thus most people tend to apply chamber areas to invert which overestimates the volume prior to surcharge or the shaft to top of benching which overestimates the volume at the surface.
Because we can now define the benching in the database, it would be better if the default dimensions for manholes were altered to represent 4 critical levels, invert, top of benching, roof, and cover. With associated areas as channel, chamber and shaft.

I would like the option to model pump station that operate using VFDs.
I would like to be able to enter the full and reduced speed pump curves for each pump station that is controlled by variable frequency drives. In addition, I would need the set point or control that causes the pumps to ramp up to full speed.

Include a new conduit type for tile drains
Add a new conduit type to model tile drains or underdrains. These are common in agricultural fields and certain stormwater control structures. Currently, its difficult to model these since you can't account for the time it takes to infiltrate from the surface to the drain based on its depth.

Graph sum of multiple objects instead of each selected object
While looking at multiple drainage areas in a basin (in my example), results can become hard to read; it would be nice if you could graph multiple objects and have the option to see the summation of the selection instead of each individual item.

Multiple Conduit Selection
The Select downstream (or upstream) links button is of limited use. Typically, I would like to select all downstream CONDUITS, in order to create a long section, but I find ICM arbitrarily include overland links (curb & gutter) between nodes and not show the conduit. I guess an SQL could be written, but a simple select conduits only button would be better.

Selection List Subtraction
I was looking for a way to subtract one selection list from another. In other words, we would like to remove overlaps between selection sets but it seems there is no way to do that easily in ICM.
It is highly recommended to include this feature for future versions as competitors such as Bentley SewerGEMS have already had this for years now.

Change Variable Speed Pumps Image
The image for Variable Speed Pumps under the "Other Special Diversion Examples" section is likely wrong. Looks like it is a copy of the image for Pump discharge pipes. Would be great if you could update with the right image! Thanks
