To estimate the average velocity in a vertical in the cross-section from point measurements v~p~ at p * flow depth, following methods are available in hymos: (iso748 and iso/tr7178):
- one-point method:
- two-point method:
- three-point method:
- four-point method:
- five-point method:
- six-point method:
- profile method, see Figure
Figure 8.2: profile
The last term in the equation assumes an extrapolation of the velocity profile to the bottom according to the power profile
