Using the Best Available
Analytical Tools and Data to
Quantify Flow Diagram
●
●
●
Published data and surveys
Estimates derived from simple
relationships
Estimates derived from models

Using an Analytical Environment
●
●
Developing pilot of flow diagram using
EXTEND software package
Features




Transparent and relatively easy for others to
review and use
Can use in “real-time” interactions with
stakeholders
Customize to include relationships from best
current knowledge
Explore different possible outcomes

Next Steps – Update 2010
●
●
●
●
●
●
Prioritize key components of flow diagram
Define / refine key theoretical relationships
Quantify detailed scenario factors
Develop evaluation criteria details
Develop response package details
Develop work plan for detailed approach
21
Next Steps - Beyond Update 2010
●
●
●
Implement long-term plan to improve
analytical tools (detailed approach)
Fill data gaps
Develop Water Plan Information Exchange
(Water PIE)
