Webflow rate in the channel, also known as discharge, is based on the continuity of flow equation or Equation 4-1. This equation states that the discharge (Q) is equivalent to the product of the channel velocity (V) and the area of flow (A). Q = V A (4-1) Where: Q = discharge, cfs V = velocity, ft/s A = flow area, ft. 2 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.
