Two Level DP-DP Model for Optimizing Multicrop Allocation of Irrigation Water

Scheduling and determining of irrigation water applications are importart considerations to increase coneern about agriculture productivity in a region of water shortage. In this paper, a two level DP-DP model has been constructed to optimize multicrop allocation of irrigation water in order to increase the benefit of whole region: The first level is to design the optimal irrigation schedule of a single crop;The second is to determine the optimal allocation of irrigation water among crops given limited water resources. A case study example indicates that the model is reasonable and the procedure is feasible. Computer programs utilized in this paper are available from the author.
