How to remove downstream lines in ArcGIS pro?

Question

Hi All,

I am working on watershed delineation and I need to remove downstream rivers based on their elevation compare to upstream and I am not sure which of geoprocessing tools in ArcGIS pro may help. Does anyone has any idea?

Thanks in advance,

I would imagine that there are some attributes on the river features to help. What does the schema look like?

If you have an elevation attribute on the lines, a Range Slider could do the trick. If there are other attributes that can reliably filter them out, then just a query definition. If your river features do not have these kinds of attributes, they could be calculated.
