Maintaining healthy rivers requires an understanding of both the physical channel conditions and the aquatic organisms that live within the channel. To explore this issue, Dr. Peter Downs co-chaired a session at the Annual Fall Meeting of the American Geophysical Union titled "Functional links between fluvial geomorphic and ecologic processes: quantifying thresholds and reference conditions.” The session was presented in two parts on Friday, December 18. A morning poster session (Session, H51D, 8am to 12:40pm) provided various case studies connecting geomorphology with aquatic ecosystem response, including a poster by John Wooster titled “How coarse is too coarse for salmon spawning substrates?” An afternoon oral presentation session (Session H53I, 1:40 to 3:40 pm) covered topics ranging from linking landscape form with riparian forest dynamics to fisheries issues.
The 2009 AGU meeting took place December 14 – 18 at the Moscone Center in San Francisco. The meeting draws a crowd of over 16,000 geophysicists from around the world and provides an opportunity for researchers, teachers, and students to present and review the latest issues affecting the Earth and its environment.
