Natural Channel Design and Fluvial Geomorphology

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).

Recommended Native Plant Species for Stream Restoration in North Carolina

Produced by Karen Hall, Ph.D.

The following links are a listing of recommended plants for stream restoration by North Carolina physiographic region based on known commercial availability.  This list is certainly not exhaustive and is intended to be used only as a basic guide.  Each restoration site is different; therefore revegetation plans should be developed on a case-by-case basis.  Not all of the plants listed in the following tables are appropriate for all restoration sites.  Consult with local plant guides and/or plant professionals if in doubt about your restoration plan.
