10.5.1 Channel Description Commands
In order to compute cross-sectional area from stage, the shape of the chan-
nel needs to be described. The IA, IC, ID, IE, IP, and IW commands are
used for this purpose.
IA - Area Rating Constants
Purpose Used to compute area of a rated channel using a rating
equation.
Format IA a.aaa, b.bbb, c.ccc
Range -10000000 to 10000000
Default IA 1.000, 1.000, 1.000
Recommended Setting. Set using WinHADCP.
Description These three parameters are used to compute area using a rating
equation for cross-sectional area of a rated channel where
Area = a.aaa * H
2
+ b.bbb * H + c.ccc
H is the stage where
H = range to surface + mounting elevation
Range to surface is the range measured by the vertical acoustic
beam and mounting elevation is from the first parameter of the
IE command.
IC – Channel Type
Purpose Sets the shape of the channel.
Format ICn
Range n = 0 (circular), 1 (trapezoidal), 2 (rectangular), 3 (arbitrary),
4 (rated)
Default IC3
Recommended Setting. Set using WinHADCP.
Description The IC command is used to select the overall shape of the
channel.
