To select a list of cells, the list is input using IS n, B where ‘n’
is the position in the list and B is the cell number. Input the
list one cell at a time. The last cell is designated by entering
9999 for the bin number. For example entering the following
will select cells 1, 3, 5, and 7 to be averaged.
IS 1, 1
IS 2, 3
IS 3, 5
IS 4, 7
IS 5, 9999
IV – Velocity Equation Constant
Purpose Sets the constants for the index velocity rating.
Format IV C1, C2, C3
Range C1 = -5 to 5, C2 = -5 to 5, C3 = -10 to 10
Default IV 0.000, 1.000, 0.000
Recommended Setting. Set using WinHADCP.
Description The IV command is used to enter the constants for the index
velocity rating using the equation:
V
index
= C1 + (C2 + C3 * H) * V
avg
Where H is the stage of the channel and V
avg
is the average
velocity of the cells selected using the IS command.
