  1. 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…

  2. Overhaul to the Hyperlinks system to allow attached data to be transportable

    ICM and Infoasset databases offer a system that allow hyperlinked documents to be connected to the database. Primarily this to allow survey, as laid and other background data to be available to the user and is a powerful function that if used correctly would allow databases to become much easier / quicker to check, improving quality and confidence. Currently the models are abstract representations of the systems, and to check detail requires arduous library time retracing other people's steps. Having the data bundled with the model is a significant improvement.

    However, two practical problems arise, since many different organizations work…

  3. 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

  4. Management of Siltation module within ICM Live

    As part of our ICM Live system we use the Siltation module. While this creates a dynamic siltation on each pipe, there isn't an easy way to manage it. Once a pipe is cleaned we need to stop the live model and potentially apply all the dynamic silt levels to the conduits as if they were observed and restart the siltation module form scratch. We need a better way. Could we have a job created for PPM (as in InfoAsset) that would reset the dynamic value on specific pipes. This could be linked to InfoAsset?

  5. Zoom graphs on either axis

    Many software suites allow the option to zoom in on both y and x axes on their graphs. However, ICM only allows zooming on the x-axis which often takes away the ability to see trends for lower or higher conditions. I am aware that it is possible to change the y-axis range in properties, but that is not desired since it requires changing the range numerous times as you pan through the data. This is a major caveat which sometimes changes our choice of modeling software, especially for systems which require heavy calibration and data visualization.

  7. 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…

  8. 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…

  9. 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.…

  10. Transportabele database (.icmt) containing an earlier version of the commited network without losing the commit history

    For the moment we can only 'branch' an earlier version from the commit history interface or 'copy' this earlier version.
    - the branch can't be disconnected from the 'mother' network
    - the copy looses the commit history
    It would be nice to deliver a .icmt file that contains only the earlier version of a network we are working on including the commit history and detached from the original network, so no branch.

  11. Promote recently used flags

    It would help if your recently used flags were promoted to the top of the flags list.

    For example, I am updating flags for some manhole surveys (flagged "SM"). Alphabetically, SM is close to the bottom of the list which means I have to scroll to find the flag. For each manhole, I am probably updating 10-15 flags each time so removing the scroll element of the flag update would save some time and frustration.

  12. Remove Need to Validate When Changing Background Layers

    Suggest that a network not need to validated or show that it was edited (red circle) for only switching on/off a background (e.g., aerial)layer would be appreciated. Keeping scenarios straight is tough enough w/out the additional heart attack when I don’t recall changing anything.

  13. Allow all objects (nodes, subcatchments etc) to be included within the ‘gauge’ objects used in the run window

    In a simulation run window the user has the choice to use a selection list of 'gauged' objects. This is useful so as to provide the results of some objects more frequently, or to only save the results from some objects and not others, in order to keep simulation data sizes down. Currently only links can be 'gauged' objects. It would be beneficial to allow all objects to be 'gauged' as currently to save the results for 1 node requires saving all objects in the model.

    (In addition, the 2D Zone is by far the most data hungry object, so…

  14. Pruning does not sub reassign drainage links correctly

    When pruning, subcatchment drainage manholes are reassigned to the first modeled downstream manhole. However, when pruning subcatchments that drain to single or multiple links, ICM gives incorrect results in some cases and doesn't work at all in other cases, which then causes validation errors after pruning. I submitted this as a bug since it gives incorrect results, but Innovyze asked me to submit is as a "feature request". So please vote for this so it can be fixed and work correctly.

  15. Using SWMM5 treatment equations at a node or link in ICM Networks

    Users would like to use SWMM5 Buildup Washoff in ICM Networks AND the SWMM5 treatment equations at a node or link in the ICM St Venant solution.

    ICM SWMM networks have both options but for the purposes of using the powerful routing solution in ICM - It would be good to have at least a treatment feature at node/link even as a simple percentage pollutant removal LID/SuDS do have this simple BMP water quality removal.

  16. 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)

  17. Sub catchment Ground Slope

    Currently ICM isn't equipped with the tools to calculate the slope from an underlying ground model or 2D zone so this will need to be determined outside of the program. Can you include the ability for the program to calculate an average catchment slope based on the 2D mesh data or ground model within each sub catchment as an option if this has not been done outside of ICM?

  18. Add 2D result labels for ICM mesh elements

    I would like to display the 2D results (depth, elevation, velocity) at each individual GRID cell using labels.
    This is currently available in XPSWMM, so I would like the same functionality in InfoWorks ICM as I would rather not have to export the data to GIS.

  19. ICM - Statistics Template: Daily events

    I want to be able to break my events into daily values. Currently this would require setting up 7 separate templates each with the unique day set under the 'Time Window' button. I want a tick option added that will allow me to do this within the single template.

  20. Rename Pages in Observed vs Predicted Graphs to Flow Monitor/ Depth Monitor nos

    Provide way to rename Pages on Observed vs Predicted Graphs to Flow Monitor/ Depth Monitor nos. If there are considerable nos of FM/ DMs, an individual has to go through page nos to find out which FM is checked/verified. Facility to rename the pages to relevant FM/DM would help quick viewing of graphs.
