The channel design problem can be treated as an optimization problem in which the objective function is minimization of construction cost. In this definition, the optimum values of section variables, i.e. side slope, bottom width, flow depth and radius, can be computed by minimizing the total...

Though the minimum area section is generally adopted for canals,it is not the least earthwork cost section as it does not involve the cost of earthwork which varies with the excavationdepth. On account of complexities of analysis, explicit designequations for minimum earthwork cost canal...

Though the minimum area section isgenerally adopted for lined canals, it is not the bestsection as it does not involve lining cost, and thecost of earthwork which varies with the excavationdepth. On account of complexities of analysis, theminimum cost design of lined canal sections has notbeen...
