c) To CANCEL incompatible point velocity
measurements delete,
i). Press the Left Soft Key.
When changes are made to the Velocity Method and Station Type, existing point
velocity measurements will be lost if the velocity method is incompatible with the
Some scenarios of velocity measurements that could be affected if changes are made to
the Velocity Method and or Station Type are listed in Table 8:3.
Table 8-3 - Incompatible Velocity Methods and Station Types
Parameter
Compatibility Result
Velocity Method
0.6 0.2 / 0.8
0.6 Measurement will be discarded. The
0.2 / 0.8 measurements must be performed.
Velocity Method
0.6 0.2 / 0.6 / 0.8
0.6 Measurement will remain. The 0.2 / 0.8
measurements must be performed.
Velocity Method
0.2 / 0.8 0.6
0.2 / 0.8 Measurements will be discarded.
The 0.6 measurement must be performed.
Station Type
Open water Edge
All velocity measurements will be
discarded. Edge station type is assigned a
“none” velocity method.
The deleting of incompatible point velocity measurements is not reversible and the user
must be certain of the decision in changing the Velocity Method and or Station Type.
Station Types 8.3.2
The Station Types developed for the Discharge Measurement technique provide
practical solutions for the different measurement scenarios that exists during field
measurements. There are several common parameters that are applicable to all station
types. There are also specific parameters, unique to each station type, that will be
discussed in this is section. The station types implemented for the discharge
measurement are the following,
• Bank (left or right),
• Island Edge,
• Open Water,
• Ice.
