Knowledge-Based Information Management for Watershed Analysis in the Pacific Northwest U.S.

We are developing a knowledge-based information management system to provide decision support for watershed analysis in the Pacific Northwest region of the U.S. The system includes: (1) a GIS interface that allows users to graphically navigate to specific provinces and watersheds and display a variety of themes and other area-specific information, (2) an analysis component that helps identify major concerns and the hierarchies of associated ecosystem processes requiring analysis, and assists the user in selecting an appropriate subset of analyses and in identifying and prioritizing data requirements and their sources, (3) a report manager that displays the history, status, and details of analyses, (4) a project manager that assists with planning and monitoring of data acquisition, and (5) a hypermedia system that provides access to information in various policy and procedure documents. The core of the system is the analysis component which contains dependency networks that link problem-solving knowledge about concerns, ecosystem processes, and data to 1Corvallis Forestry Sciences Laboratory 3200 SW Jefferson Way Corvallis, OR 97331 USA Telephone: 503-750-7434 FAX: 503-750-7329 Email: reynoldsk@fsl.orst.edu
