| Abstract: | A logarithmic velocity profile is often fitted to velocity data in order to calculate the friction velocity (u
*) and typify the surface texture by a roughness length (z
o
). A method is given for estimating the errors in these parameters as calculated by this method. An example is given in which
the size of the error is compared with the fluctuations that typically occur in the time seriesu
*(t) andz
o
(t). |
