Analysis of the Stability of the Irrigation Optimization Solutions

Due to the fact that water crises becomes more expressed, in planing of irrigation system is necessary to apply optimization methods. The optimal solution is made upon defined criteria. In this paper, the analysis of solution stability of optimum irrigation for two criteria is given. The area Žestilja in Karašica – Vučica river basin, in the northern part of Croatia is chosen for this analysis. Four irrigation methods have been proposed: linear self propelled device – linear, self propelled sectorial sprayer –typhon and irrigation trough an underground pipe system – sub-irrigation. The corresponding model was established and an optimum solution was analysed taking into account the input data and predefined model limitations. The first solution made for the criterion of realization the maximum profit, and the second one for the minimum of water consumption. The two solutions, in the next step, must be analysed, and a stabile solution, satisfactory for all users, is obtained.
