WebDesign of Irrigation Channels Making Use of the Lacey Theory: The full supply discharge for any canal is always fixed before starting a design. The value of ‘f’ for particular site may be calculated using equation (11) or if CVR is given then f = m 2. Thus when Q and f are known design can be done in the following steps: i. bin collection uttlesfordWebThe following procedure is used for the design of non-alluvial channels by Manning's formula. Similar procedure applies for the design by Chezy's equation.
