The following are resources on water measurement.  No particular order to
these....


1) Article on use of a manometer on 90° elbows to estimate flow -- This file
is 7+MB, still want it? 

2) Link to the United State Bureau of Reclamation (USBR) web site for design
of ramp flumes (low cost, relatively easy to construct, adaptable to
difference channel X-sections.)  This site also lists commercially available
ramp flumes.
