Abstract

OPTIMIZATION and modeling of the pressurized irrigation systems in other to reduce their construction costs has attracted many scientists up to the present time. OPTIMIZATION of these irrigation systems has often been conducted by using available commercial codes or toolboxes of conventional evolutionary algorithms combined with hydraulic models. The code developed in the present research which is based on one of the powerful methods of OPTIMIZATION, e.g. GENETIC ALGORITHM, assigns an integer numeric value to each available diameter. Then, to determine the optimum diameters in the pipe network, the cross-over, mutation and reinsertion with elitism approach is applied on set of chromosomes and an integer numeric for each pipe diameter is then selected. Obtained data from OPTIMIZATION subroutine is then sent to another subroutine that has been developed to simulate the WATER HAMMER pressure. Maximum pressure due to the WATER HAMMER phenomenon in each network pipe is calculated in this subroutine. Calculated maximum pressures are sent back to the OPTIMIZATION subroutine where constrains of the working pressure are substituted by the bursting pressure constrains. Exchange of information between the OPTIMIZATION model and the hammer model continues so that the calculated optimal diameters do not change anymore. The results showed that compared to the existing design conditions, optimized design by the present model reduces cost of implementation of pipelines in ISMAIL ABAD IRRIGATION NETWORK from $825935.28 to $730958.37 which is equivalent to 11.5% of the total cost of pipeline implementation. Also the results showed that by changing the diameter of 3 pipes out of 16 existing pipes the excess pressure of the WATER HAMMER due to the rapid closing of all valve at the end of pipelines in less than 1 second can be controlled. In this case the cost of implementing the pipelines increases by 6.1% e.g. from $730958.37 to $775511.5.
