WebAn irrigation canal is to be designed for a discharge of 40m/s with ground slope of 1.5×10. The bed material has a size of 2mm. Calculate the dimensions of the canal. What would be the dimensions of this canal if it was to be designed on the basis of Kennedy method with C.V.R equal to 0.85. Web1. Calculate the culvert design flows (Section 3-3.1) 2. Determine the allowable headwater elevation (Section 3-3.2) 3. Determine the tailwater elevation at the design flow (Section 3-3.3) 4. Determine the type of control that exists at the design flow(s), either inlet control or outlet control (Section 3-3.4) 5.
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. WebFeb 2, 2024 · DESIGN OF THE CANAL. In the design of a canal one has to find out bed width (B) depth (D), longitudinal slope (S), and velocity of flow (V). If discharge (Q) and silt factor (f) are given, the method of finding. This aspect limits only finding the sectional dimensions of the canal. But how to compute the discharge ata particular reach is an ...
