Tracer ABCD (Water Overlay)

Constructions with a positive SUBSTANCE Attribute are known as chemical emitters. Constructions with a negatice SUBSTANCE Attribute are known as chemical decomposers.

Chemical emitters are constructions which produce specific chemicals. The net amount of chemicals a single construction creates is spread out across it's surface. After the chemicals are created, any water flowing through the same location will carry a part of the chemicals with it.

Structures which are defined to create a negative amount of chemicals function as a scrubber or decomposer, removing the specified quantity of chemicals from the hydrological model.

In situations where water is absent, chemicals will not be moved between cells.

Notes

• Chemical emitters must be constructions on the surface, not underground constructions.
• Chemical emitters's attributes do not take the form of function values, and thus must be added manually or as part of loading in geodata.
• Chemicals have generic definitions, in terms of name and magnitude, to allow for the modeling of arbitrary substances.
