  1. Use Machine Learning to estimate subcatchment inflows to network

    Allow users to skip parameterized subcatchment hydrology estimates which may become outdated over time and replace it with machine learning on measured data from TSDB.

    Flow meter could train algorithm which learns to predict flows based on rainfall. This flow is then allocated to upstream contributing subcatchments.
    As TSDB grows, flow forecasts potentially improve.

  2. Additional keyboard shortcuts

    Keyboard shortcuts can really help speed up processes and workflows in InfoWorks ICM but some of the menu options do not yet have these. Would it be possible to add the missing keyboard shortcuts, specifically for repeatable tasks such as updating objects from ground models?

  3. Allow to import generic (geo)TIFF into Spatial TSDB

    Currently the only GeoTIFF standard supported in ICM Spatial TSDB is the MeteoGroup standard. But some Authorities in Germany deliver rainfall data as generic TIFF.
    It would be nice to extend the import feature to a generic GeoTIFF format.

  4. Part load ICM results

    It would be helpful if you could open a specific part of a results file for a completed simulation run. For instance, schedule and complete a 10 year timeseries run but only load the last year of results.

    As others have mentioned on here, the option to open part of a bigger results file would limit the unnecessary long regeneration times, you could pick which variables you would like to load e.g. runoff only or depths and flows, and you could perform reports on part of the results.

    I appreciate I can run shorter periods i.e. yearly data rather than…

  5. Export both the result and the underlying property fields

    When the model results are displayed on the webpage through Exchange, since the basic properties need to be viewed, the corresponding basic properties of the results need to be exported first, and then the results are matched to the basic properties according to the ID for display. It is hoped that the option of exporting the basic properties and results together could be added

  6. Option to pan through 2 or multiple geoplans at the same time

    Sometimes (in ICM and IAM) in comparing 2 (or more) networks visually the networks are most of the time tiled horizontally of vertically. But when panning through one network, it would be very convenient that the other network(s) is/are also moving.
    Suggestion: An option to visually connect different networks. One is the main and the other networks will be the connected and they will all get the same size. The connected networks will get the zoom factor and the extents of the main network. While panning through one of the networks (preferably the main network) the others will follow.

  7. Support for Hong Kong Observatory Rainfall Data

    The Hong Kong Observatory is the authority responsible for producing observed and forecast rainfall data for the territory. Their data is produced in a format not currently supported in ICMLive so we have to convert it into shape files to be used. Direct reading of this data would enable both more efficient data loading processes as well as reducing the potential for errors.

  8. Enhance import/export of SWMM models for ICM platform

    Enhance model import from SWMM5 INP files to include a few of the Open Data Import Center /Open Data Export Center options:
    • Only update existing records
    • Ignore existing objects
    • Overwrite, Merge, etc.
    • Export Selection only
    Ultimately we want to have a central model copy but have the ability to easily push out and in simple EPASWMM INP files for developers and others. When a new SWMM INP file comes back from another modeler, we’d like a good way to update the existing model from that.
    It would be great if this applied to both SWMM and…

  9. Add node level (hydraulic grade line) data to custom graphs for calibration

    Allow for the ability to compare observed and predicted level data (or hydraulic grade lines) at nodes. Instead of depth in the pipe, I typically have water surface elevations at a node, specifically for treatment plant hydraulic modeling.

  10. Increased number of user pollutants

    We would like to be able to trace pollutant sources through our 2D model. The way to do this would be to use the user defined pollutants . But... at the moment there are only four pollutants and potentially we'd have many different sources that we'd like to track. Can the number of user pollutants be increased? We can't give a number that this would need to be increased but it could be several hundred.

    Thanks for this, I assume that as long as the end goal of being able to trace a significant number of sources through the 2D is met this would be sufficient? As in it is not actually pollutants you wish to be able to trace but rather the source of flows?

  11. As a user, I would like to be able to import polygon with holes in it (donut) as subcatchments,

    So that I can model situation part of the drainage area is not draining to the storm sewer system.

  12. Convergence Errors be resolved automatically while the model is simulated

    Sometime a TSR running for few weeks throws up convergence hence these sims need to be rerun with shorter timestep which is both inefficient and a lot of time is wasted. It would be good if somehow the simulations dialog allowed to run the model with Max and Min timestep so that when it encounters convergence there after the model runs with shorter timestep. (I understand the model does timestep halving but even then it fails to converge)

    Hello,

    Thank you for this, there is already a mechanism available for achieving something very similar to this. If you have a network and then go to the simulation parameters for this network via Model > Model parameters > Simulation parameters then within these there is an entry for “Max number of timestep halvings”. Depending on the timestep in the run dialog and the entry in the simulation parameters here you will be able to determine the minimum computational timestep that the engine goes to before failing a simulation.

    Hope this helps.

  13. 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.

  14. Allocate a subcatchment’s flows among several nodes

    This is an idea from CDM Smith == I have an engine feature idea that has occurred to me at various times but never acted on. Today I was discussing an InfoWorks model with a junior colleague. It would clearly help us in this model to be able to allocate a subcatchment’s flows among several nodes, whether identically or according to specified proportions. In this case, we’re filling out an existing model that previously had all 10” and larger pipes in town to now include all the 8” as well, tripling the size of the model. We’re basing new subcatchments…

    There is the ability to drain a subcatchment laterally to multiple links in InfoWorks ICM, would this be a close enough representation? When looking to split subcatchment flows across multiple nodes, this is usually achieved by splitting the subcatchments so there is one available for each node which is to be drained to.

  15. RTC rule themes

    It would be great if it was possible to theme in the GeoPlan on the basis of the rules which are active for a given object at the visible timestep.

  16. Application of design storms in ICMLive

    We'd like to be able to predefine some design storms in ICMLive (note that this is NOT the same as design rainfall in ICM). The idea is that we'd have these storms that could be optionally applied by operators to see the likely effect of a rainfall event. Essentially we are looking for the same functionality that existed in FloodWorks.

  17. Use ruby to edit rainfall dialogue box

    Exporting rainfall files to csv for manipulation creates details of the storm events themselves, we would like to be able to change the return periods, durations, multiplying factors shown in the rainfall dialogue editor instead.

  18. Select which result variables you want to save

    The more functionalities become available in ICM, the larger results files grow and the less manageable they become (especially when running longer time series). In most cases people are only interested in very specific results (e.g. depth, flows, ... and not such things as all the detailed runoff components). So if one would be able to select at the simulation schedule which variables were to be stored), results file sizes (and hence results querying !) could be reduced enormeously.

  19. As a user, I would like the computing time to be reported as clock time rather than CPU time in XPSWMM 2D

    I just noticed this when trying to run a test on model speed. This is with the “CPU” Extreme option and 4 CPUs selected. The clock time is about 16 minutes, but the elapsed time is showing at 58 (close to 16x4). I think the ET is counting CPU time, and not clock time. While CPU time is interesting, I think it would be better to report clock time if you’re going to label it “Elapsed Time”.

    Perhaps a separate “CPU Time” line would be appropriate when using multiple CPUs.

  20. Set database management permissions

    (Workgroup) database permissions are now mainly used to prevent users from modifying content within the database, but there is currently no way to prevent them from updating databases, creating new ones unlimitedly on servers with otherwise protected access etc. It would therefore be useful to have an additional security level which deals with database management permissions.

    Thank you for this request.

    There are already settings available for database creation permissions which can be implemented using the snumbat.ini file.

    Specifically there is a keyword “AllowDatabaseCreation” where a setting of 0 means creation is disallowed and a settings of 1 means creation is allowed. The Workgroup Data Server Administration document which can be requested from Innovyze talks through these steps and provides examples for the snumbat.ini files.

    When it comes to the updating of databases, is this to restrict the ability to update from a particular software version database to a later one or rather to prevent update to the contents of the database please?

    Thanks,
    Pascal
