This is a quick, simple graphical method to determine
the volume of water flowing through open channels such as
canals, ditches, flumes, masonry conduits and other
natural or artificial waterways. The nomograph is based on
the equation for determining velocity in open channels
using the variables of roughness coefficient, wetted
perimeter, hydraulic gradient, and wetted area. Each
variable can be identified on the graph and the velocity
determined. Laminated plastic.
