Optimization of irrigation scheduling for complex water distribution using mixed integer quadratic programming (MIQP)

International audienceIrrigation scheduling is necessary to ensure the fair water distribution between end-users and to organize gate keepers work. After analyzing water distribution issues at a secondary sector of the Gignac Canal, we developed an approach to optimize water delivery of on-demand distribution policies. MIQP was used to solve such problem. Within irrigation network, water resources and manpower for gate operation constraints, we built an objective function for dual goal: as close as possible to demand load profile and less manpower work. This method will be illustrated for scheduling off-take turnouts of an example chosen from a secondary command area of the Gignac Canal
