Title Records.
This area allows the user to input descriptive strings, up to about 80 characters
long, for use in identifying data sets. Extra characters will be truncated, not
wrapped.
Calculation Options.
Variable to Calculate. The dropdown menu allows the user to choose
the variable to be calculated without having to leave data blank for that particular
variable. Choices are: normal depth, bottom width, energy slope, hydraulic
roughness, and water discharge.
Compositing Method. SAM offers four compositing methods: alpha,
equal velocity, total force, and conveyance.
Geometry. The three choices here are simple channel (single
trapezoidal channel), compound channel (up to three, `stacked,' trapezoidal
channels), and station-elevation.
Flow Data
Water Discharges.
SAM data records accept a maximum of 10 data points per data type. This
area allows the user to input discharge (cfs), water surface elevation (ft), energy
slope (ft/ft), and temperature (F)
Enter Geometry Data
This button opens the screen for geometry input according to the choice made
in the Calculation Options box. Geometry input will be discussed later.
" + " Box.
This button toggles, opens/closes, a small window which will receive selected
output. The output coming to this window cannot be selected by the user.
Print Flow Distribution
When this box is checked, SAM will add the results of the flow distribution
calculations to the output file.
