Hi! I'm now modeling solute transport in a Karst area. Chlorine was used as a tracer for its steady and unreactive property.
The source of Cl is mainly from rainfall leaching soil. So it is a planar input with the rainfall. But I'm very confused how to fulfill importing Chlorine into my model through rainfall. Is it in the "Mass transport boundaries" or "Mass transport materials"? Please tell me the specific steps.
Looking forward to your reply! Thanks!
