Regional Curves

Bankfull hydraulic geometry relationships, also called regional curves, were first developed by Dunne and Leopold (1978), and relate bankfull channel dimensions to drainage area.  Gage station analyses throughout the United States have shown that bankfull discharge has an average return interval of about 1.5 years or 67% annual exceedence probability.  The primary purpose for developing regional curves is to aid in identifying bankfull stage and dimension in an un-gaged watershed and to help estimate the bankfull dimension and discharge for natural channel designs.

Macroinvertebrate Taxonomy and Assessment

Benthic macroinvertebrate larvae (aquatic insects) play key roles in many regulatory water quality programs in North Carolina. Not only are these insects used to detect water pollution problems, but are also used to determine if streams are perennial features, and are proposed for use in stream restoration projects as success criteria. This workshop introduces the participants to the basic ecology and taxonomy of aquatic insects. Most of the emphasis is on learning family level identification of mayflies, stoneflies and caddisflies (or EPT).
