Can you add a proposed building elevation directly into the ICM model?
I received the ICM model from the City of San Marcos and was wondering if I can add a proposed building elevation directly into the model to see how the floodplain reacts?
0 votesIn many cases, buildings are added either as voids, or as a mesh or roughness zone.

Variable 2D roughness at low depths
When applying direct rainfall onto 2D zones traditional roughness values do not typically apply, especially where the depths of water on the mesh element are very small. Often the workaround is to apply much higher roughness values in order to 'slow the flow'. It would be helpful to have a depth varying roughness that could be phased out as the water depth increases. This would put ICM in line with how TUFLOW and Flood Modeller Pro deal with the problem.

GIM and infiltration zones
When rainfall is applied to the 2D mesh with infiltration zones, it would be advantageous to have a GIM module that works with the infiltration zones, their infiltration model (i.e. Horton) and the sewer system to represent rainfall induce infiltration more effectively.
13 votesHello,
There is already capability to take an infiltration zone in InfoWorks ICM and to route this to the 1D network directly as a contribution. This can be done by using a permeable zone object in conjunction with the infiltration zone (2D) object.
Thanks.

support (geo)tiff format as ground model format
geo tiff is a more efficient format using less disk space, widely accepted.
5 votesWe are pleased to announce that this functionality has now been completed and is available with 2021.2 of InfoWorks ICM.

Mesh result smoothing
Automated smoothing of flood depths from mesh elements, giving a less jagged appearance.

Reduce validation time of models with river banks or inline banks
Current validation of models with bank lines takes a long long time for larger models, Up to several hours. My first guess is that checking a vertice bank level against the mesh level is the probelm. Same thing happens when you want to update ground levels from the mesh. This is also very very slow. It would help productivity speed if this could be reduced significantly
1 voteThank you for this request, improvements for validation times with inline banks were introduced with 2021.1.1 of InfoWorks ICM, this now takes significantly less time than it did before.

New polygon to represent "buildings" geometry and hydrology
This polygon would allow the user to set the roughness, porosity and flood threshold level all within a single polygon object - negating the need for many overlapping ones. Furthermore, the user is able to set the runoff characteristics for the building. These will be generated as per subcatchment with a single runoff surface and routed to the specified location. Additionally, the user has the ability to set a capacity limit, any flow above this will be capped from entering the 1D network. Instead the flow will be passed out on to the elements surrounding the building. Much as the…
