A system of mathematical models for managing water and land resources of the irrigation system, taking into account economic indicators and environmental consequences

The paper examines a system of mathematical models for managing water and land resources of the irrigation system, taking into account economic indicators and environmental consequences. Calculations were made for the conditions of the Levo-Egorlyk irrigation system (Stavropol Territory) for 1956-1985. The problem was solved in 2 stages: at the first stage the Pareto-optimal set was determined, at the second stage an analysis was carried out taking into account integral criteria. The obtained calculation results indicate the possibility of using the system of models in planning and managing water use of the irrigation system.
