<br />The advantages of ueiDl discharge characteristics rather than stream
<br />order Include: (1) discharge character1sticll relate in.Eormat1on about the
<br />quanti'tyof ,'Wat'er floiw1ng past a given stream point and the size of the
<br />'catcbaent;(2)tbe Mthodll' of derivil1g the dnta are sta12dardtzed and
<br />accepted;{3-) th.problelDS with identifying llnd def1ninl~ the
<br />characteristice of interrupted, intermittent" braided and delta streams are
<br />elilll1nated. StrealDS originating froDl lakes, springs, or wetlands can be
<br />meaningfully characterized because discharge and drainage area can be
<br />quantified or when the watershed is undefinable, phydc.il characteristics
<br />can be utilized; and (4) diacharge aDd area figures corl,espond to real,
<br />a5certainable conditione as opposed to subjective evalulltions of
<br />tributaries on a up (Hughes and Omernik 1981). Differl!nt ecological
<br />characteristics can be related to discharge per unit arl!a such as
<br />0.040-0.090 T1J3/sec/km2 and a mean annual discharge rangE' of 2-502 m3/sec
<br />such as that for the Siletz River. The result is a motE! realistic
<br />comparison of watershed characteristiCS and grester predictive valu.!.
