How to accumulate flow

[SaraAlian]

I'm trying to find a way to accumulate some flow values along the stream network (from the inlet all the way down to the outlet across the stream catchments).. I'm working with NHDPlus V2 data ( streams and catchments) and GPS data points as my study points. All the data is in vector format. I read about ArcHydro and worked with the tool but it was confusing and not helpful. I'm wondering if you could help me finr the answer.

Copy of question: Flow accumulation with ArcHydro .

I assume that you are not trying to establish the flow accumulation in a web environment using the JavaScript API. In that case, you may want to remove this question and let people answer the similar question you posted in the Arc Hydro Place.
