Hi all,

For my dissertation I'm modelling flow through wetlands. Objectives include evaluating positioning and type of reeds - ammonia concentration and pressure drop being the main methods of comparison. I've reduced the complexity of the problem by assuming porous regions for the reeds.

In short, ammonia levels deplete within the reed beds. Hence I'd like to include this source within the model. Is it possible for me to apply a negative mass source with respect to ammonia and positive source (of same magnitude) hence representing the change in composition within these regions?

Im very new to SWX Flow Sim. If anyone can help or suggest an alternative way of modelling this it would be much appreciated.

Thanks,

Sophie
