Eutrophication Simulation

I want to simulate eutrophication.Which one is I need to reference (1)Water Quality Modeling, (2)Sediment Transport Modeling or (3)Toxics Fate and Transport Modelingin the EFDC_Explorer10 Knowledge Base?

Eutrophication is related to Water Quality Modeling. However, sometimes it is advisable to also add a cohesive sediment class to simulate reduced light penetration into the water column.
