The sensitivity analysis for the rectangular and trapezoidal canal section design has revealed that the optimum is less sensitive to the increase in bed width and more sensitive otherwise. A natural channel is a stream in equilibrium, which is neither silting nor scouring over a period of time. Canal cross‐section designs for uniform flows are contrasted and compared by using nondimensional shape parameters. Objectives of Channel Design. Vedernikov  (see also, ... Factors such as cracks, weed growth, and incompatible construction materials may cause increasing seepage losses (Uchdadiya and Patel, 2014). This type of canal alignment problem is addressed in this chapter. The mass losses (2-D infiltration, rate qi per unit length in X-direction) obey either Richards’s PDE (Van Genuchten’s sand) or Vedernikov’s theory (non-capillary sand). At the commanding inlet of a lattice (period is L) of equidistant trenches laid at a topographic slope S0, water is released through a cross-sectional area A0(0) of a trench, at a volumetric rate Q. Sand’s hydraulic conductivity and bed’s roughness are Ks and n. Longitudinal flow downslope (in the X-direction) is gradually varying and MAR takes place at the trench segment 0 Standard CS Templates-> Canal Profile 2. 1.
