Status/Schedule: FYOI-06: This projcct was schcduled for completion in FY05 but will be
ex.tended into FY06 because of the additional field work around the November 2004 high-flow
test. No additional field work is scheduled, and FY06 will scrve as the final reporting year for
this project, including results of the November 2004 High-Flow sediment test..

Reports published to date:

. Rubin, D.M., 2004, A simple autocorrelation algorithm for determining grain size
from digital images of sediment: Sedimentology.
. NAU 2005 Fact Sheet.
. Hazel, J.E., Jr., Topping, D.1., Schmidt, J.C., Kaplinski, M., and Melis, T.S.,

roles of eddy and channel storage for the Colorado River in Marble Canyon, AZ, in
press.
. Topping and others, 2004, High-resolution monitoring of suspended-sediment
concentration and grain size in the Colorado River in Grand Canyon using a laser-
acoustic system.
. Melis and other, 2003, Testing laser-based sensors for continuous in situ monitoring
of suspended sediment in the Colorado River, Arizona.

Expected Products/Deliverables:

. Final report summarizing the findings of the FIST project, including an assessment of
sandbar changes between 2000 and 2005 and the effects of the November 2004 high-
flow test.
. 2-3 more peer-reviewedjoumal articles or USGS reports during FY 2006.
. All reach data from this project delivered to the GCMRC database coordinator during
FY2006 as scheduled under the original project timeline defined in FY2001.
. Reporting of the results of the November 2004 sediment experiment at the 2005
Science Symposium

Integration: This project is closely integrated with the Integrated Quality-of-Water Project,
particularly the fine sediment mass balance.

Implications of Experimental vs. Non-Experimental Scenarios: None here, as there is no
High-Flow Sediment Experimental treatment proposed. Funding is maintained at the originally
proposed level so as to accomplish final reporting on the November 2004 sediment experiment.
