Well,

Tag to stream morphometric studies, like Strahler books.

Regards

Perhaps you will find something in my paper on Stream Types and Management Implecations uploaded into Researchgate. Drainage density can be variable, even within same physiographic area. Even with estimated stream distance, one needs drainage area to calculate drainage density. LiDAR coverage with its high resolution DEM detail can yield improvement over normal 1:24k topographic mapping and will help if you want to include most of the definable ephemeral, intermittent and perennial stream channel network.

Interesting question
