Asymmetrical Tanks

Currently ICM treats storage areas where there is a change in area at a certain level as symmetrical. This limits hydraulic modelling by constraining the structures that can be built. An option to account for asymmetry would be useful ( similar to...

simulation .elog file available via UI

Prior to ICM 2025, right clicking on the completed simulation > Open As would give access to the "simulation log", which contained useful details about the initialisation and failure reasons of the simulation. It would also contain diagnostics ...

SWMM Export from InfoDrainage

Certain authorities use other SWMM-based software for review purposes or as their city-wide model that needs to be updated. We need to export a SWMM file for more universal submittal purposes, even if InfoDrainage uses a modified SWMM engine.

Add ability to use custom curve number tables other than the default TR-55

Many jurisdictions publish their own set of curve numbers for different land uses which they will expect to see during plan review. The local curve number sets often differ from TR-55. Please allow us to build custom curve number sets based on lan...

Multiple return period hydrograph

Currently, InfoDrainage restricts each hydrograph to a single return period, which creates inefficiencies when analyzing stormwater systems across multiple design storms. To accommodate analyses for 2-, 10-, and 100-year events, for example, users...

Junction Loss

There need to be more options for calculating junction loss. Having values for entry and exit loss isn't enough. Recommend HEC-22 and AASHTO at a minimum.

Need for flexible rainfall assignment in 2D zones

In models created using ICM by Japanese users, it is not uncommon for both approaches—one where rainfall is applied to subcatchments and flood from the network flows over 2D elements, and another where rainfall is applied directly to the 2D zone—t...

Default tank symbol

Can you change the default tank symbol color back to the dark blue that it used to be? The teal color is very light, making it difficult to see and hard to differentiate from the reservoir symbol. I know I can change this in preferences, but it wo...
