Optimal and Economic Water Allocation in Irrigation and Drainage Network Using ICA Algorithm (Case Study: Sofi-Chay Network)

Water scarcity especially in Iran and the recent drought, achieving a water policy is of important particular. Optimal water collocation under controlled and climatic and real conditions, in the past two decades, it has been one of the major concerns of researchers and engineers. The main purpose of this research is to use the imperialist competitive algorithm (ICA) to estimate and water allocation. the imperialist competitive algorithm is a new optimization algorithm and compared with other optimization has par or even higher ability to optimize a variety of issues. This algorithm for finding the optimal solution is speed. In other words, an optimal convergence rate is high and can find global optimized in optimization problems. In this study, ICA was used for optimizing water resources values from 1991 to 2003 agriculture years about the Sofi-Chay drainage network to achieve the most optimal policy. The results of the application of the ICA to the issue of water allocation and compared with genetic algorithm results indicate that the proposed method is very successful. The results showed that the results of the implementation of the ICA algorithm in comparison with the genetic algorithm are very close to the measured values of water allocated. The results showed that the results of the implementation of the ICA algorithm compared with the Genetic algorithm is very close to the measured values of water allocated. Also, the results showed that the lowest amount of water allocation in the 4th study area in 1997-2003 and the highest amount of water allocation in the 1st study area in 1991-1994 and 1998-1999. The results showed that the results of the implementation of the ICA algorithm in comparison with the genetic algorithm are very close to the measured values of water allocated. Also, the results showed that the lowest amount of water allocation in the 4th study area in 1997-2003 and the highest amount of water allocation in the 1st study area in 1991-1994 and 1998-1999. The results also indicate that generally, optimal water resource allocation between different parts (agriculture and services), 40% of the proceeds is recovering from the current situation.
