1 Improving Function in Stream Projects Robby Bowen James Jones Steve Jones, Ph.D.

2 OBJECTIVES HAVE HISTORICALLY FOCUSED ON STABILITY AND SEDIMENT TRANSPORT Stability Analysis Sediment Transport Analysis

3 DOES THE BIOTIC COMMUNITY RESPOND TO ATTEMPTS TO IMPROVE HABITAT IN NATURAL CHANNEL DESIGN PROJECTS? IS HABITAT INFLUENCED BY W/D RATIO IN SAND BED STREAMS? IS THERE A RELATIONSHIP OF INCREASED USE OF WOOD AND FUNCTIONAL RESPONSE? DOES THE TYPE OF STRUCTURE INFLUENCE FUNCTIONAL RESPONSE?

4 IS HABITAT INFLUENCED BY W/D RATIO IN SAND BED STREAMS? Brushy Creek Greenville County, SC: W/D = 8.9 (C5) Pew Creek Gwinnett County, GA: W/D = 5.9 (E5) Falling Creek Jones County, GA: W/D = 8.0 (C5)
