Using SWMM5 treatment equations at a node or link in ICM Networks

Users would like to use SWMM5 Buildup Washoff in ICM Networks AND the SWMM5 treatment equations at a node or link in the ICM St Venant solution. ICM SWMM networks have both options but for the purposes of using the powerful routing solution in I...

Can ICM add particle tracking module?

When there are pollutants that enter a system from various sources then it would be good to have pollutant tracing functionality which shows the source and the pollutant moving through the system, giving an idea of the rate at which it travels and...

odour

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 modelli...

Modelling of mud and other non-Newtonian flows

We've a lot of work at the moment modelling the failure of tailings dams. Tailings dams typically have material that acts in a non-Newtonian manner. To effectively model these sorts of fluids would require the inclusion of additional fluid propert...

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...

Allow pollutographs to apply on subcatchments

At the moment it is not possible to set a pollutograph for subcatchments, and the modeller is obliged first to run the hydrology, export the hydrograph, re-import the hydrograph as inflow, and finally re-run with a pollutograph

Modelling of Septicity

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 ...

Calculatiton speed with diffusion needs to improve.

Diffusion will seriously slow down the model culculation. But generally the water quality models have to run for several years. With current simulation speed that would be unlikely to do a water quality simulation with diffusion.

Local water quality settings.

User can set local water quality parameters and local initial condition of Water Quality in ICM rather than globally. Local WQ parameter should at least contain decay rate, DO process coefficient etc.. As for the local initial condition, DO concen...

"jet flow" and agitation (inflow with a certain speed)

In China, efforts are being made to improve black and smelly water bodies. One of the measures is to increase water fluidity to improve water quality through natural purification of water bodies. So there are two measures to increase the fluidity ...
