Eutrophication

I want to know what data needs to be prepared to simulate the eutrophication of a reservoir?And is there a tutorial or video that simulate the eutrophication of a reservoir?

Please have a look at the following step-by-step guide for developing a water quality model using EFDC_Explorer: https://eemodelingsystem.atlassian.net/wiki/spaces/EHG/pages/3407891/Building+a+2D+Lake+Water+Quality+Model+Level+2+Step-by-Step+Guidance
