trying to create a web-based map of the Rouge River watershed that allows water flow to be traced as well as using the profile tool to look at topography...HELP!
I'd start with Web AppBuilder for ArcGIS, specifically the Developer Edition. You can use it to connect to either your ArcGIS Online organization or Portal for ArcGIS instance. Web AppBuilder enables you to create and deploy new custom web apps without having to code.
To enable water flow tracing, you could leverage the built-in analysis tools in ArcGIS Online with the Analysis widget. For example, there's the:
Note that executing these tools will consume credits.
For the elevation profile capability, there is a great custom widget developed by Robert Scheitlin, GISP that you can use available here:
Elevation Profile Widget Version 2.17 - 9/19/2020

Hope this helps,
I'm really new to GIS work...what are you talking about when you said "executing these tools will consume credits"?
For the particular analysis tools that I mentioned, behind the scenes, you would be using data and analysis operations within ArcGIS Online. These are not free and consume credits. Learn more here,
Understand credits—ArcGIS Online Help | ArcGIS
I believe every ArcGIS Online organization subscription includes an allotment of credits. It's best to check with your local Esri account manager or Distributor.
If you want to avoid using credits, then you would have to create and publish your own water network dataset and the trace, watershed, and viewshed tools as web services.
Can credits be purchased or earned?
Yes, you can buy additional ArcGIS Online credits. As you work in education, I suggest you look into the education special programs, Special programs
