Evaluating progress and restoration planning in the Yakima Basin: a re-examine of the EDT Framework and Model Greg Blair, ICF International Yakima Basin Science and Management Conference June 2011 I’m Greg Blair, member of the development team for the Ecosystem Diagnosis and Treatment model. I’d like to thank you for the opportunity to talk about Ecosystem Diagnosis and Treatment and how it can be used to solve natural resource problems. In presentation I will provide a brief background of EDT and its application in the Yakima Basin, most of my presentation will be to provide present some ideas on use of models in resource management and an introduction to EDT3 the latest version of the EDT model that represents a major advance in the EDT software.

As you can see the user interface looks very different from the previous system. Whereas EDT2 relied on Microsoft Access and Excel for data management and reporting, EDT3 is built around a stand-alone desktop application. This allows us to more easily and efficiently customize the system for our clients, and to stay compatible with new technologies such as Windows 7. Notice in this screen shot we see this green light here in the lower left-hand corner, indicating that the software is communicating with the EDT Server using Web Services. The geometry view provides the tools needed for clients to define the boundaries of their EDT analysis, and to describe the spatial structure of their system. In EDT3 Geometry is defined first by points called “nodes”. At least two nodes are required to describe a place in space such as a stream reach, defined by a path or line between two nodes. Nodes are used to describe stream reach breaks, places in the system where the stream converges (such as a tributary) or where the stream diverges (such as a point of withdrawal). Nodes can also be used to define where the system re-converges, such as a bypass. In all these cases we use nodes to georeference the geometry, and to describe its configuration. The pathways between nodes are used to organize the environmental information, including the surface area of the environment (lengths & widths in streams and rivers), composition of the habitat, and the condition of environmental attributes. All of these are associated with a specific stream reach. To work with geometry data the user selects the “Geometry” view from the “Diagnosis” menu. Particular data sets can be browsed in the “Data Explorer” region after logging in and selecting a project. The geometry set can also be accessed at any time by right clicking on the data set in the Data Explorer, and choosing “load”. Shown is the Sacramento Bay/Delta Geometry from our Bay/Delta EDT project, and loaded it into the module. In the geometry module there are tabs for managing reaches & nodes. On the Reaches tab you can delete reaches, create them, create nodes, and revert the data if errors are made. You can also assign the “Environmental Type” of a reach such as “stream”, “estuary”, “obstruction” etc., and you can associate the reach with a fine-scale HUC; although the reach is automatically associated with the HUC that each geometry set is in. On the nodes tab you can create nodes and define their coordinates. If you have permissions for a project you can save changes to the server, or create a new geometry dataset from an existing one.

Our latest reporting tools are more sophisticated and flexible than our previous version. Report requests are submitted to the system from the “Reports” view found in the “Diagnosis” menu. Here is a screen shot of the current version of the reports view, and I should point out that not all of these report types are active yet. However, this list provides a good snapshot of the report types that have been requested by the current EDT user community. New report types will be developed under new and future projects, and they will be added to this view for everyone to use after they are enabled.
