Optimization Model of Rotation Irrigation Channel Distribution with GA and FS

Optimal water distribution in irrigation district (ID) is an important method and countermeasure for reasonably restraining the water requirements, effectively increasing the water supply, and actively protecting the ecological environment etc. According to the genetic theory, it is essential to discarding the traditional binary system coding for solving water distribution. Considering GA sinking into the partial solution easily, a free search algorithm is introduced. It extend the search space for algorithms, enhancing the quality of gene coding, adjusting the discharge of canal , making every canal closed at the same time, decreasing the discarding water of canal, reducing the time of manual work. It has excellent theoretical and realistic effect on distributing water.
