Strahler stream order

Question

I have a layer of line objects representing stream channels. These have been generated at 50K scale but do not have a Strahler order designation. The tutorials I've seen using the SAGA extension in QGIS all start at converting a DEM. I don't need this step. Is it possible to produce Strahler order on a vector layer of connected lines?

A few years ago I wrote a QGIS plugin named Strahler which achieves precisely what you're looking for. Unfortunately it is only compatible with QGIS 2.* because I stopped its maintenance. It might be useful for you though.
