In CWMS, a watershed is a set of data, information, models, and images that represent watershed lands and the channels, gages, and water control features within the watershed. The Setup module is the grouping of commands for watershed setup. These are commands for configuring inputs, models, and outputs that describe a watershed's behavior. You develop a visual representation of the watershed to display in the CAVI that is map-based. This chapter describes the Setup module, which includes an overview of the Setup module interface, how to create a new watershed, and reports on watershed setup.
In the Setup module, you configure your watershed's physical arrangement, including Map Layers and time series icons.
Because the order of program execution (Program Order) is a fundamental part of the watershed setup, you should define it early in the process of constructing your watershed. This involves determining the set of programs for CWMS to execute, the order of program execution, and the data flow between model applications. You may also define supplemental programs and add them to the program order so they are executed from CWMS. A supplemental program is a program or script that you develop (not included in the standard setup).
