spillway

**MAKE A NEW DIRECTORY WHERE ALL OF THE FILES WILL BE LOCATED. YOU MUST
HAVE A DIRECTORY PREPARED!**

-   Sites program is located on CCE computers @ ***Start* -- *All
    Programs* -- *Engineering Applications* -- *SITES*** -- Click on
    *Sites* Icon

-   Help menu provides explanation of each menu item and can be accessed
    any time.

-   [Select]{.underline} ***Help \-- Sites IDE Interface*** The Program
    consist of 5 separate and different parts. The menu changes for each
    part or interface and the transfer between each part is not always
    clear. To exit help click on black X in upper right corner to close
    the interface.

-   [Select]{.underline} ***File*** (This menu changes each time the
    program goes back to the Main Menu and changes interfaces)

-   [Select]{.underline} ***New Project*** \-- Moves to the directory
    you prepared and at the top line **enter a new folder name** to
    place all of the files for this project that SITES produces.
    ***OK*** goes back to Main Menu.

-   [Select]{.underline} ***File New*** changes Main Menu and enters the
    next interface with new menu items available.

    format. Next Screen

-   *Watershed Schematic-*- [Click]{.underline} on the first icon on the
    left which looks like an arrow pointing upward that represents a dam
    and it will place a dam icon on the schematic. **Next [double
    click]{.underline} on the newly placed icon** to input data for that
    particular dam.

    floods), **Low Point on embankment centerline**. Next Screen

-   *Auxiliary Spillway (AS) Crest* -- *OPTIONS*: [select]{.underline}
    **Stability/Rating**.

-   [Select]{.underline} *CREST DATA*: **Tie in Station** for Downstream
    Crest, [Enter]{.underline} **Crest Elevation** in feet for auxiliary
    spillway crest. Next Screen

-   *Auxiliary Spillway Inlet Template **-- ***[enter]{.underline}
    **Mannings "n"** (.04) or **Vegetal Retardance** (5.6) value,

-   

> Inlet Template -- distance is upstream from the tie in station of the

    Home Screen Menu and new interface)

-   **File --** [select]{.underline} **Save As** (Save the file you
    constructed as a unique **filename.d2c**)

-   The new menu and interface now gives you the opportunity to
    [check]{.underline} (Check File) the created file or to [process
    it]{.underline} with **Build File.** (Build file means run program
    and if you have not saved the input file you must do it now or loose
    all data)

-   [Select]{.underline} **View --** The **Summary Table** provides a
    table output that can be printed. Also if you click on the file name
    at the top of each column, the bottom menu is available to **view
    graphs**, **view text**, etc. If the view text does not work you can
    see the text output in the directory created at the start. The
    **filename.out** file is a detailed text of the SITES run including
    errors in input that can be viewed with any text editor or MS Word.
