River Restoration Survey Clarifications

TERMINOLOGY CLARIFICATIONS

Strahler Stream Order:
Strahler's (1952) stream order system is a simple method of classifying stream segments based on the number of tributaries upstream. A stream with no tributaries (headwater stream) is considered a first order stream. A segment downstream of the confluence of two first order streams is a second order stream. Thus, a n^th order stream is always located downstream of the confluence of two (n-1)^th order streams.
