What is the Quantity Coefficient
Generator?
A field confirmation is a manual depth, velocity, or quantity
measurement taken at a monitoring point. Field confirmations are
used to verify the accuracy of flow monitor data and are necessary
when developing the coefficient variables of the flow quantification
equations, Manning and Colebrook-White. Profile uses field
confirmations and the Quantity Coefficient Generator to solve for
the following equation coefficients:
• Hydraulic Coefficient (HC) The HC is used in the modified
Manning's flow equation and represents the interaction between
pipe slope and friction
factors related to the velocity of the
flow.
• Roughness and Slope These coefficients are used in the
modified Colebrook-White flow equation and are an indication
of the pipe roughness and slope values at the monitoring point.
When you want to quantify flow based on depth-only data, use the
Quantity Coefficient Generator to solve for one or all of the flow
equation coefficients.
You also can use the Quantity Coefficient Generator to enter and
store Silt and Offset/Gain coefficients.
The Quantity Coefficient Generator provides a historical record
of the field confirmations for a location and monitoring point and
can be used to track trends and flow characteristics over time.
