Morning All,

I am currently working on a project in ICM using a 2D overland mesh to evaluate known flooding locations.

When viewing flood depths, is there a way to distinguish between flooding from the combined system and the storm system? A simple grid report of the manholes and splitting the total flood volume by system and % is do-able, however I was thinking something more advanced such as a visible trace of flooding from manholes of different systems. Can a pollutant be used for this? I should note that I have the model set up so rainfall does not fall on the mesh where there are subcatchments.

Any ideas or experience?
