Research Components:

l. Numerical model development and application: Fine sediment transport models
are currently in use and under development. Research includes flume studies and
detailed flow measurements of sediment transport dynamics. Water temperature
model development is underway. Research includes detailed measurements of heat
exchange between the river and the atmosphere; water temperature dynamics in
backwater habitat areas.
2. Real-time two-way telemetry: A system is being developed to provide two-way
telemetry between the office and instrumentation in the Canyon. The two-way
communication not only provides real-time access to data, but also allows the user
full control of the instrument from the office. The system is being developed in a
generic fashion to allow use with any instrument that uses serial communications.

MO's and IN's ADDRESSED: Goals 7 and 8; MO's 7.1, 7.2, 7.3, 7.4, and 8.1; CMIN's 7.1.1,
7.2.1,7.3.1,7.4.1,7.4.2,8.1.2,8.1.3.

Status/Schedule: FY02-06: Monitoring activities are ongoing and scheduled to continue.
Analysis of the November 2004 high-flow test data is scheduled to continue into FY06.
Completion of the initial phase of suspended-sediment transport model development is scheduled
to be completed in FY05 with continued refinement in FY06. Water quality model development
to continue with scheduled completion of the water temperature component in FY06.

Expected ProductslDeliverables:

. Preliminary real-time data posted to World-Wide-Web for some sites for parameters
that do not require extensive processing.
. Preliminary data made available in real-time through the GCMRC Oracle database
using the in-development two-way telemetry system.
. Final, reviewed data made available through GCMRC Oracle database annually.
. Annual Open-File Reports summarizing methods and collected data.
. Peer-reviewed publications where appropriate, including assessment of the November
2004 high-flow test.
. Presentations at AMWGiTWG meetings as well as other professional meetings.
. Numerical models made available for general use at appropriate time.

Integration: The fine sediment mass balance project is intimately linked with the fine sediment
storage project because the mass balance should track with changes in storage. The water quality
project will become integrated with the new aquatic foodbase program as it develops.
