  2. Our clients would like to see InfoWorks ICM apply daylight savings time corrections to wastewater and tradewaste inflows

    As a toggle setting in the run settings or in a wastewater/tradewaste pattern, this would shift the diurnal patterns based on the simulation date and daylight savings time start/end dates instead of working on standard time all year long. Mathematically, this is really straightforward, but may require internal indexes (and warning messages?) for the DST start/end dates. It would also require something to turn this feature on and off as there are several areas that do not observe DST. This feature would help us more accurately predict combined sewer overflow volumes and durations where base wastewater flow has a significant…

  3. Circular sluices/penstocks would also be useful

    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)

  4. Improve ground infiltration simulation parameters.

    Could we have a 'Node level affects groundwater infiltration' for the soil store please?
    This simulation parameter was introduced to InfoWorks ICM recently to limit infiltration from the ground store to the model. Could this be extended to limit flows from the soil store as well?
    As often when are using models for design purposes, infiltration can become excessive in design events compared to verification. Therefore we have to manually reduce soil store inflow, often requiring new limiting discharge orifices and nodes at each subcatchment with GI applied. Thanks

  5. Calculating volume storage on river reaches

    In the application of ICM, we often count the regulation volume of river channels.But at the moment we can only calculatethe total available volume of channels/river reaches between two cross sections by using length and cross sectional areas.If the number of river sections is very large in the model,it will take a lot of time and effort to accomplish this work. It would be great to have the tool to calculate volume storage on river reaches automatically.

  6. bottom opening

    Beside an upstanding vertical orrifice, it would be practical to be able to implement horizontal 'bottom holes' from one node to an underlaying node. e.g when a ditch can drain to an underlying conduit by means of a bottom opening. This might be a more straight forward implementation then the weir circumference workround method which is now often used. if possible both circular and rectangular.

  7. Simulation engine control update

    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!

    IN DISCUSSION  ·  pascal.lang responded

    Thank you for the addition of this request, we are in discussions about how this might be achieved as the level of awareness of tasks is varied between agents. Would a dashboard showing who sent which simulation where (which are still ongoing) be sufficient? This would be without the progress those simulations have already made available as a first step.

  8. blockage

    Applying pipe blockage is a standard required in Australia and the functionality in ICM to do this is not user friendly (using blockage links). A simple % pipe blockage in the conduit properties should really be an option. This is particular the case for cross drainage and also orifice and pipes leaving detention basins (where a pit isnt used)

  9. Wide "Oval" shape ID

    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.

  10. Orifice to limit flow in both directions

    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.

  12. Can ICM add particle tracking module?

    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.

  14. Merge pond and storage nodes and increase their functionality

    Pond nodes:
    - allow variable infiltration at different levels (up to 3 different rates)
    - allow variable perimeter with level i.e. plan area through which side infiltration can occurs can vary
    - no porosity function

    Storage nodes:
    - 1 porosity value (which only works below ground, above ground it is assumed to be 100%)
    - fixed perimeter for infiltration i.e. assumes cylindrical shape for infiltration (despite the plan area changing with level)
    - fixed infiltration rate (no change with height)

    It is not possible to model both porosity and a change in infiltration with height.

    I propose that pond and…

  16. Allow the user to choose the flood type of pond or storage nodes

    Allow the user to choose the flood type of pond or storage nodes from a drop down as is the case for manholes. As opposed to the current state where the flood type depends on the relationship between the highest level entry in the storage array and the ground level of the node.

    From help file: "Storage nodes or ponds can flood. If the highest level entry is below ground level, the pond is considered to have a roof at that level and is therefore sealed. If the highest level entry is equal to the ground level then any water…

  17. 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.

    Great 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.

  18. 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,
    Ann

  19. 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…

  20. Pump Station Modelling

    Infoworks ICM pump station modelling principle is very basic, adding a pump between two nodes is highly hypothetical. There is no way to add pump station head losses.
    I would like to suggest incorporating pump station modelling (for Rotodynamic pumps) with pump curve and system curve theory. Then the model results would be much more realistic.
    There must be a tool to incorporate all the accessories in pump stations, between two nodes. Like pump station type, drywall wet well. And Parameters to calculate Pump suction and discharge losses, like all fittings, non-return valves, discharge valves, flow meters etc. This would…
