To avoid endless work around discusions on how to model a rectengular flap valve when only circular flap valves can be implemented in a model, having the option to model with rectangular flap valves would be verry usefull.

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.

Similar to the rectangular flap valve request, circular sluices would avoid workarounds trying to estimate the rectangular equivalent to a half closed circular penstock (or worse still a half closed egg shaped penstock)

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.

Client feedback: an automatic check for colliding pipes would be highly appreciated to avoid nightmares in the construction.

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,
Ann

Provide RDII Analyst without needing to purchase InfoSWMM

Since the beginning of ICM and allowing to send simulation to other computers in the network, there was a need for knowing exactly who is currently sending simulations and to which computer. Please update the ICM with this improved functionality for the normal user, not for admin only. These people are the ones who send simulation to the network, not IT people!

conduit shape ID "Oval" only allows Height > With. So for "horizontally" wide oval conduits a new conduit shape has te be defined. It would be practical if the standard "Oval" also allows a with greater than the hight.

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.

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.

Pipe grade calculator between US and DS inverts, Ultimately having the ability to calculate downstream or upstream inverts over a long network based on a specified grade from either a DS or US invert level as a starting point.

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.

When there are pollutants that enter a system from various sources then it would be good to have pollutant tracing functionality which shows the source and the pollutant moving through the system, giving an idea of the rate at which it travels and impacts areas downstream.

Provide cross section conveyance for each cross section

Provide a easy model/network transport option from one program to the other. Many municipalities within WA utilise XPSWMM and therefore are note able to read an ICM model.

A limiting discharge set on an orifice should limit flow in both directions. Currently, the orifice limits flow in the forward direction; however, flow can go in the reverse direction at an unlimited rate. Hydraulically, if there is a physical feature that limits flow, it seems that it would limit to (for example) <10 l/s and > - 10 l/s.

At the moment it is possible to have non straight survey sections brought in, which may result in incorrect cross section lengths, straightening these was possible in RS, it would be good to have the same in ICM.
