abstract: "Parent item:
Maisbich (Luxemburg), data from discharge meter Q4 (Qup), 2006-12 and later
Measuring instrument:
Maisbich basin: V-notch discharge meter Q4 (Qup)
Type: Van Essen TD-Driver, SN 19613
This instrument measures pressure with one absolute sensor. It also measures temperature.
Height V-notch above sensor: 0.0018m.

Datasets with correction contain the corrected discharge observed at the Vnotch.
The discharge is calculated as Q=Cd*h^2.5
After correcting the logger measurements with hand measured depths we interpolated the difference (dH)
Then we determined the factor Cd with discharge measurements which we also interpolated
The timing of hand measurements can be corrected to better represent the logged values

The last corrections (variable "clean_corr") were made for blocking of the V-notch weir as folows:
z1 represents the last good discharge value after which sedimentation slowly starts blocking the weir
z2 represents the moment when the blocking is max
z3 represents the moment just before cleaning of the weir
z4 represents the moment after cleaning of the weir
The max difference in discharge is Q(z3)-Q(z4)"
