WORK PLAN
Time line (FY 1999 to project end): List MAJOR tasks and deliverables by fiscal year and indicate key staff
responsible for each.

Prior to October 1, 1998

• Preliminary results of both the field data analysis and the wind/cowling flume work will have been presented at a conference sponsored by the American Geophysical Union and one sponsored jointly by the Woods Hole Oceanographic Institution and the Office of Naval Research.
• Numerous historical wind data sets will have been assembled from multiple sources, including the USGS, Everglades National Park and the South Florida Water Management District.

• Conclusion of preliminary analysis of laboratory wind-driven flow data and creation of draft fact sheet.
• Conclusion of analysis of historical field wind data and creation of draft fact sheet.
• Provision of updated wind data to USGS surface water flow modelers for use in the Taylor Slough region model.

• Formulation of initial wind stress momentum transfer relationships for flow models of South Florida.
• Conclusion of analysis of laboratory wind-driven flow data and publication of fact sheet.
• Publication of fact sheet on analysis of historical field wind data in the Taylor Slough region.

• Integration of wind stress formulation into flow model of South Florida and conclusion of preliminary testing of these formulations.
• Update of fact sheets as necessary.

• Final refinement of wind stress formulations for flow models of South Florida.
• Directorís approval of peer-reviewed journal article describing wind characteristics of Taylor Slough region.
• Directorís approval of peer-reviewed journal article describing results of wind cowling/flume experiments.

FY 1999 activities: Statement of the work to be undertaken in FY 1999 and a description of the methods and procedures.

Activities for this fiscal year will consist primarily of analysis, summarization and publication of the data accumulated from historical field sites and the wind cowling/flume experiments. In addition, these data will be processed in such a way that it can be passed along as necessary for use in the USGSís surface water flow model of the Taylor Slough region.

Historical field wind data will be analyzed to identify the important space and time scales of variation. This analysis will be done using simple statistical methods as well as more advanced techniques such as spectral analysis and empirical orthogonal function analysis.

The wind cowling/flume data will be analyzed to construct a formulation by which the momentum transfer from wind to water in the presence of emergent sawgrass can be represented. This will be done by constructing momentum balances for the flume experiments and by analyzing differences in vertical profiles of horizontal water velocities in the presence and absence of wind as measured in the flume.

FY 1999 deliverables/products: Describe in more detail the specific deliverables/products that will result from this work in FY 1999.

As stated in the timeline above, the deliverable products of this project include two fact sheets and two peer-reviewed journal articles or conference papers. In addition, wind data to drive the USGSís surface water flow model of the Taylor Slough region will be provided as needed. Lastly, an improved momentum transfer formulation will be provided for the Taylor Slough region model.

FY 1999 outreach: Emphasizing FY 1999, describe plans to address client requirements, decisions, and deadlines. New directions or major changes for FY 1999 (if applicable):

The fact sheets and articles described above will be distributed and the results will be presented at appropriate interagency meetings where those interested in modeling surface water flow in South Florida are in attendance. Results will also be presented at professional scientific and engineering conferences when appropriate.

ACCOMPLISHMENTS, OUTCOMES, PRODUCTS, OUTREACH
FY 1998 accomplishments and outcomes, including outreach:

• Preliminary results of the historical data analysis and a description of the wind cowling/flume work were presented at the Spring Meeting of the American Geophysical Union
• Results of both the historical wind data analysis and the wind cowling/flume work are to be presented in September, 1998 as an invited presentation at a conference sponsored by the Woods Hole Oceanographic Institution and the Office of Naval Research.
• Current, processed and analyzed high-quality wind data were provided for the USGS model of the Taylor Slough region in the Everglades. These data made a substantial improvement in the behavior of flow in the southern portion of the model.

FY 1998 deliverables, products completed:

• Presentation at the AGU Spring Meeting as described above.
• Provision of wind data for USGS modeling as described above.

PROJECT SUPPORT REQUIREMENTS
Names and expertise (e.g. carbonate petrology) of key project staff (list by fiscal year for duration of project):

This project is led by a Research Hydrologist, Harry Jenter, who is overseeing all of the work as well as performing a majority of the data analysis and presentation. This is expected to require full-time involvement for FY 99

Other required expertise for which no individual has been identified (list by fiscal year for duration of project):

Additional personnel, probably at the GS-9 to GS- 11 level, will be required to process the large amount of historical data that have been accumulated to date, and to process the large amount of laboratory data collected. This need is expected for 3-4 months of FY 99 only.

Major equipment/facility needs (list by fiscal year for duration of project):

There are no major equipment needs for this project for FY 99. The wind cowling/flume will have been shutdown by the beginning of this fiscal year.
