Abstract

Design of a minimum cost canal section involves minimization of the sum of costs per unit length of the canal, subject to uniform flow condition. These costs are included with costs related to covering every meter of channel length, the cost per cubic meter earthworks and costs associated with WATER LOSS (including seepage and evaporation losses) as the objective function is considered in this study. Seepage and evaporation are forms of WATER LOSS in an irrigation canal, while the seepage loss depends on the canal geometry and evaporation loss is proportional to the area of free surface. In this study, the main constraint equation is Manning’s Formula. In addition, the minimum permissible velocity and Froud’s number are used for optimizing design canal as subsidiary constraints. In this study the OPTIMIZATION algorithm based on directly search is used and a computer program in MATLAB was developed to solve the above mentioned equations. Feasibility simplex and optimal design to minimize costs of per unit of length of canal is improving with obtained non-dimension carves from results. Studies comparing results with other researchers, can be seen the effect of further constraints and earthworks and cover costs related to the final dimensions of the channel.
