WEAP is structured as a set of five different "views" of your area. These views are listed as graphical icons on the "View Bar", located on the left of the screen. Click an icon in the View Bar to select one of the views. For the Results and Scenario Explorer view, WEAP will calculate scenarios before the view is displayed, if any changes have been made to the system or the scenarios.
The Schematic View is the starting point for all activities in WEAP. A central feature of WEAP is its easy-to-use "drag and drop" graphical interface used to describe and visualize the physical features of the water supply and demand system. This spatial layout is called the schematic. You can create, edit and view it in the Schematic View. GIS layers can be added for clarity and impact. The Schematic View provides you with one-click access to your entire analysis--right click on any element in the schematic to access its data or results.
The Data View is the place where you create your data structures, models and assumptions in WEAP. In the Data View, the screen is divided into four panes. On the top left, a hierarchical tree is used to create and organize data structures under six major categories Key Assumptions, Demand Sites, Hydrology, Supply and Resources, Environment, and Other Assumptions. The tree is also used to select the data to be edited, which is shown on the right of the screen. For example, clicking on the "Demand Sites" tree branch on the left of the screen, will display the data for all demand sites on the right of the screen. On the bottom left is a data inset schematic. Clicking on an element in the schematic will result in a jump to its place on the tree. On the top-right of the screen, a data entry table is used to edit data and create modeling relationships. The information you enter here is displayed graphically in the bottom right pane.
The Results View displays a wide variety of charts and tables covering each aspect of the system: demand, supply, costs, and environmental loadings. Customizable reports can be viewed for one or more scenarios. You can also use the "Favorites" option to bookmark the most useful charts for your analysis.
The Scenario Explorer View is used to group together "Favorite" charts (created earlier in the "Results" view) into "Overviews" for simultaneous display. With Overviews, you can get a birds-eye perspective on different important aspects of your system, such as demands, coverage, flows, storage levels, environmental impacts and costs. You can create multiple Overviews, each of which can display up to 25 different Favorites. In addition to showing Results, the Scenario Explorer View can display selected Data across many scenarios, to help demonstrate the impact of various assumptions and policies on results. These input values can be changed on the spot and WEAP will recalculate and update the results.
The Notes View is a simple word processing tool with which you can enter documentation and references for each branch of the tree. To edit the notes, either type directly into the Notes Window, or select Edit to display a larger window with additional word-processing features. Notes can include formatting (bold, underline, fonts, etc.) and can also include standard Windows "objects" such as spreadsheets. Use the Print and Print All buttons () to print one or all of the notes or the Word buttons to export one or all of the notes to Microsoft Word. We highly recommend extensive use of notes to document each scenario.
Tip: If you are working on a low-resolution screen, we suggest that you hide the View Bar to make more space on the screen. Use the menu option View: View Bar to do this. You will then need to use the View menu to select the different views.
