• Install HEC-RTS using the self-extracting exe file (i.e., C:\Programs) – double- click on "HEC-RTS 3.1.1.exe".


    • HEC- RAS Install - If HEC-RAS Version 5.0.7 has not been installed on your computer then do the following:

Before running HEC-RTS 3.1.1 for the first time, the user needs to decide on a general location that will contain all HEC-RTS watersheds. It is recommend that the Users directory should not be selected, but a location be chosen that other users can easily access. The user will create the directory using Windows File Explorer. The first time HEC-RTS is run, the user will be asked to agree to the terms and conditions for HEC-RTS, as well as the terms and conditions for the individual modeling software.
HEC-RTS has a requirement for watersheds to be stored in a location. Since this is the first time that HEC-RTS has been run, a No Watershed Locations message window will appear (Figure 2.1) letting the user know that watershed locations have not been defined and would the user like to create a watershed location. If the user clicks Yes, the No Watershed Locations message window will close (Figure 2.1), and the Create Watershed Locations dialog box (Figure 2.2) will open. The user can now define watershed locations (Chapter 3). If the user clicks No, the No Watershed Locations message window will close (Figure 2.1), and the user can create watershed locations later on (Chapter 3, Section 3.2).
