1. The Role of Decision Support Systems and Other Tools in Watershed Planning Rick Farnsworth Bernie Engel Jon Bartholic Rich Zdanowicz Watershed Planning in the Great Lakes Region: Exploring Future Collaborative Opportunities and Partnerships October 26, 2004 Detroit Marriott Renaissance Center

2. Outline 1. e-Decision Support Systems 2. Midwest Partnership Approach 3. New Components 4. Summary

3. What is e-DDS? Information Technology + Decision Support System Information Technology + Decision Support System DatabasesDatabases Simulation modelsSimulation models Decision modelsDecision models User interfacesUser interfaces Decision support system (DSS) consists of that decision makers use to evaluate the economic and environmental impacts of competing alternatives. Role

4. e-DSS: Key Elements Client-based (problem driven)Client-based (problem driven) Internet-basedInternet-based –User-friendly interface –Decisions in a few clicks or screens GIS-based (thin client)GIS-based (thin client) Science-basedScience-based

5. Midwest Partnership Approach Development and implementation of a standard for other watershed management DSSDevelopment and implementation of a standard for other watershed management DSS –Promoting data initiatives –Relating specific tools to planning process phases and learning objectives –Creating systems where outputs of tools can be plugged into other models Development, promotion, and use of web-based, user-friendly, geo-spatial watershed management data, decision support tools, and systemsDevelopment, promotion, and use of web-based, user-friendly, geo-spatial watershed management data, decision support tools, and systems

19. New DSS Components: Data Sharing Access to all our databases. Our data layers can be added to your data layers.

20. New DSS Components: Data Sharing

21. Watershed Decision Support System Data Models System Yes, and we are sharing Several models and we are linking them Building a small system using available tools
