Our clients are more and more trying to figure out if damage to a property is caused by water from the public area (which is the responsibility of the client) or from private areas (which is not). When rainfall on mesh can pick up a tracer (eg. from existing objects like infiltration zones or roughness zones) we think we'll be able to better help our clients.

I would like Innovyze (Autodesk)to provide more resources to actively review the great suggestions in this this forum. However it seems that months and even years go past and the suggestions just sit there showing as received.

For example : the possiblity of changing the precision in the labels (the decimal number of the value )

The ability to have a mesh zone on a mesh zone. This would be useful when modelling Attenuation basins in 3D (using ground model / breaklines). It would easily allow to have a coarse mesh for the basin floor to improve the stability of Outfall 2Ds (where small triangles can limit flow to the outfall 2D) but still allow for a finer mesh for basin sides and in your study area.

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.

Air Phase Model Function - Can Innovyze consider to include air phase modelling function in InfoWorks? At moment, the odour modelling is done separately by various methods using the sewer hydraulic data as the input. As a result, the odour modelling has to be done by different teams and often costing. There is a strong market demand to integrate the liquid and air phase modelling, for example DHI already has a function. It is technically challenging to have a full integration, however there are well developed simplified ways to achieve that.

1. For shear-stress-based design 1.1 Max Shear Stress (in N/m2 with at least 1 digit after the decimal point) 1.2 Hydraulic Slope at Max Shear Stress (in percent with at least 3 digits after the decimal point)
2. For velocity-based design 2.1. Max SPEED2D (already available. Good job, devlopment team!) 2.2. Hydraulic slope at max SPEED2D (in percent with at least 3 digits after the decimal point)

To be able to easily split a subcatchment into 2 separate subcatchments.

For example when it becomes obvious that the flow from a subcatchment cannot be collected at a pit (node), it becomes necessary to insert an additional pit (node) to capture flows. The subcatchment needs to be easily split (say with a general line) into 2 separate subcatchments with similar data other than the new areas.

You will find in the attached document a frequent encountered example of a bottom orifices.

Boundary lines generated with the Thiessen Polygon methodology to define the boundaries for different rain gauges are too thin when they are automatically generated inside ICM. This make them quite difficult to see when a model is loaded with many different type of objects as sub catchments, mesh zones, roughness zones, etc.

Providing our users with the ability to change thickness/colour/line type in a new row in the Properties and Themes, will allow a better visualization, therefore, better understanding in the Geoplan on how each rain gauge affect different zones of the model.

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

In GIS software when editing features, there is often an option to select a number of vertices to delete/move them as a group. This would speed up time taken to edit features in the model like roughness zones that often need a lot of editing to be compatible with the mesh.

In my opinion it would be very useful if you could make the same adjustments in one stretch for a selected set of scenario's. Similar to an adjustement you make in the base scenario that effects all the underlaying scenario's but than for a specific selection of scenario's. It would be handy to restore an error that occurs in several scenario's (scenario' that are all a copy from the same scenario)

I want to change the amount of decimals when I apply Autolabels in Properties and Themes. Right now the default is three decimal places which I cannot edit.

When we display the graph of the discharge (flow through line) of a results section (line object), we don’t have access of the information about the volume (usually when we display a discharge graph, the volume is indicated at the bottom of the graph, but it’s not the case with a results section).
It could be interesting to have this information about the volume (especially because the results section are a tool very useful to use).
