Using an Analytical EnvironmentUsing 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 2010Next 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
22
Next Steps - Beyond Update 2010Next Steps - Beyond Update 2010
● Implement long-term plan to improve analytical tools (detailed approach)
● Fill data gaps● Develop Water Plan Information Exchange
(Water PIE)
