Hi Paul,

Can I make a suggestion regarding the InterfaceUtils.exe utility?

Seeing that we are now dealing with considerably more rainfall data associated with ARR2016/2019 rainfall & temporal patterns, can Innovyze (or whoever created the abovementioned utility) look at updating the executable such that one doesn’t have to browse for a particular file in the “File name” field. As an alternative, it would be handy if we had the option to simply update the file name manually in the “File name” field and press a “reload button”. Furthermore, it would also be beneficial if there was an additional function to choose the previously chosen catchment and results parameters.

As it is, the “File Name” field can be manually updated but it does not reload the file.

An update to the utility as indicated above will make the process of exporting results quicker and more efficient.

Kind Regards

The current procedure for ‘Numerical Correction’ in ICM requires users to remove any existing values to calculate the correction (for Preismann and Base flow) before the inbuilt routine is run. If this wasn't made the calculated correction values are added on top of any existing value thereby reducing the total storage in the system. However, the correction for 'Storage Compensation' deletes any existing values before calculating the compensation value. Therefore, there is inconsistency in the approach which has the potential to reduce the total storage at a node. Either, the inbuilt process for 'Numerical Correction' should be revisited or the help document updated such that users are aware of this limitation.

For XPSWMM and Infoworks (any GUI editor you have actually):

Moving an existing line substantially is something that occasionally happens. If we could do this without having to delete the entire thing, or click and drag each vertex one at a time, it would be a big help at times.

A new feature I’d like to see for lines/polygons is a ‘realign feature’ tool. When selected, if you clicked on a vertex in a line or on a polygon boundary (single click and release), it would ‘grab’ that vertex and allow you to move it. Once you place it by clicking, when you move the mouse either direction along the line, it would AUTOMATICALLY grab the next vertex on the line. Right-clicking would bring up a menu allowing you to ‘release’ the line (leaving the ‘grabbed’ vertex in its original location), delete the grabbed vertex, insert a new vertex, or ‘skip’ a vertex and move up/down the line. Once you deleted the vertex or inserted a new vertex, it would again automatically grab the next vertex either direction based on the mouse movement.

At least at first, when you select the tool, it would be good to have a window explaining how it works (with a checkbox to make it stop appearing).

Does InfoWorks ICM have an equivalent to an ideal pump in SWMM which pumps whatever is entering the SPS out of the SPS?

It would be a good feature to include into infoworks as I needed to play around a bit to get it. I found I had to add line 2 or the pump kept on turning off rather than flow pacing.

I have seen a screw pump used previously to pump out what comes into the SPS but dependent upon the head discharge parameters this can back up the incoming sewer. If I set a curve similar to the following should this work if the discharge at 0.1m head is significantly in excess of the maximum flow rate or given the fact that there is such a huge variation in flow across a small head change is this likely to cause problems.

If I need to adjust the head range I suppose I could drop the pump on and off levels so that the model wont back up the incoming network.

As a sewer modeller I have occasionally been asked about odour generation in sewer networks. I have noticed that DO (dissolved oxygen) and BOD (biochemical oxygen demand) are both inputs in the wastewater and trade-waste model groups of Infoworks ICM SE. Given that these are possible inputs in a sewer model, is it possible to model the consumption of DO by BOD within the network to determine where and when the sewage becomes anaerobic and prone to odour generation? This would be particularly useful if you wanted to model the addition of a high BOD low volume trade waste stream into sewer reticulation system and you wanted to know if the trade waste could be diluted sufficiently so as not to become anaerobic while in transit.
