Focused on four broad areas
1) Conceptual model of diversion outcomes and management
endpoints
2) Hydrodynamic modeling and data collection to optimize
diversion operations
3) Modeling ecological effects of diversions to further assess
risk and uncertainty
4) Short- and long-term needs and considerations in social
science analysis

Broad Takeaway Messages
Broad Takeaway Messages
2012 Master Plan is cornerstone for restoration project planning but
does not provide details on implementation and approach for
planning diversions.
Data collection and modeling in Mississippi River comprehensive,
and excellent analysis in West Bay; next step should be to evaluate
impacts of diversion openings under various operation strategies.
Successful application of ecosystem models requires assessing
risks, using multiple models, linking to physical and social models,
conducting monitoring, making appropriate model selections, and
conducting marsh experiments.
Social science research and analysis is inadequate, and accordingly
there is a need to quickly make progress on identifying roles for
social science and analysis in planning for diversions.

Expert Panel on Diversion Planning and Implementation: Meeting #3 October 28, 2014

Why are there no Panel members from Louisiana? Experts from Louisiana are in fact currently engaged and leading much of the work The Panel was established to review and advise the CPRA and the teams that are engaged in these efforts What authority does the Panel have? We are not a decision-making panel We will provide expert advice and recommendations for consideration Is the Panel reviewing the decisions made in the Master Plan? No, the Panel is advising on science and research needs related to advancing and further developing/designing sediment diversion projects that were in the 2012 Comprehensive Master Plan

Recommendations Timeframe for Implementation Fall 2014 Panel Meeting 1. Articulate an expanded view of the technical approach in planning for diversions. 2. Focus data collection and hydrodynamic modeling on optimizing diversion operation. 3. Provide presentations of ongoing ecosystems modeling efforts. 4. Develop a review process to examine adequacy of monitoring data. 5. Conduct whole-marsh experiment to understand impacts of combined effects of erosion, nutrients, and salinity. 6. Develop a process to identify conflicts, tradeoffs, benefits and risks associated with diversions. 7. Link longer-term social science research to key diversion questions. 12-18 months (or less) Fall 2014 Panel Meeting 12-18 months (or less) 12-18 months (or more) 12-18 months (or less) 2-3 years
