Апстракт

A model of the water management system is developed by connecting the technical and economic parameters that best represent the regional irrigation subsystems. The following technical parameters were analyzed: the location of water intake, configuration, and dimensions of the primary canal network, pipelines, and the number and location of pumping stations. Economic parameters depend on the technical ones and they are necessary investments for construction (€), unit investments (€/ha), investments for replacement of equipment during the period of exploitation (€), annual irrigation costs, and fixed irrigation costs (€/ha, €/m3), energy consumption and cost (kW, yearly h, yearly €), economic price of irrigation (€/ha, €/m3), break-even point analysis. The model was tested on the future regional subsystem "Telečka" with an area of about 25,145.00 ha, which will be part of the regional system "Severna Bačka" (AP Vojvodina, Northern Serbia). Based on the specified parameters, 6 potential variants for construction have been proposed. By ranking the stated quantitative parameters, the best effects are achieved in the 4.1 variant of the technical solution with the following values: total investments for the construction of 42.05 million €, unit investments of 1,670.00 €/ha, investments for equipment replacement of 4.20 million € every 10 years, costs of irrigation on the water intake 130.00 €/ha, fixed costs of irrigation 86.00 €/ha, economic price of irrigation 203.00 €/ha (for d.r. 6%). For the calculation of these parameters, data from the technical part of the plan was used, in which a large number of experts from different professions were involved. An improved planning methodology (using a simulation model) as well as the obtained technical and economic data can be used for comparison with other regional subsystems that are in similar conditions (e.g. climatic, soil, available water resources).
