The graphical user interface (GUI) is the steering wheel of HEC-RTS. The GUI features graphical menus and tools organized by function, or modules. The four modules are:

  • Setup for watershed configuration.
  • Acquisition for data acquisition, monitoring, validation, and editing.
  • Visualization for viewing data.
  • Modeling for setting up and executing analysis software for forecasting and viewing results.


This chapter provides an overview of the GUI and basic functions. Here are three navigation tips:

  • For simplicity, the GUI "hides" commands that are not applicable to the module or element the user is working on. Thus, if an option appears to be missing, make sure that the correct module or element has been selected and that the option is applicable for that selection.
  • Directory trees list elements configured in the watershed. When a user configures a new element, it will be added to the directory tree.
  • Commands related to a selected element are typically accessible by right-clicking on the element.
