Flow through Weir Notches 
1107 
SUMMARY 
(1) The discharges through rectangular and Cipolletti notches when 
plotted logarithmically do not give straight lines and therefore can not 
be represented correctly by a formula of the type Q = CLH n . It was 
found, however, in the case of the rectangular notches experimented with 
and the heads of water run, that a straight-line formula could be deduced 
that within the range of the experiments gave values quite close to the 
experimental data.
