A Project serves as a container for all the different parts that together form the complete representation of a watershed. Control Specifications are one of the main components of a Project, and are principally used to control Simulation Runs. The remainder of the Project components are described in later sections. This section describes how to create and manage Projects. It also includes information on how the file system is used by the program to organize and access the files that represent the Project components. Finally, it describes the Control Specifications.
