The FREGAT Sprinkling System is the main sprinkling system in Russia, and in the Volga region region. Design data of this system constantly changed in the course of its long-term operation, as well as in result of new watering technologies and constructive decisions introduction into production that led to divergences in comparison with technical parameters of watering. There was a need for developing hydrodynamic model of the FREGAT DMU-463-90 system performance allowing to make numerical

Theoretical researches on determining parameters of creating hydrodynamic model of the sprinkling system were conducted; the model of the linear system of water use on length of the sprinkling system is created and the modes of optimum work the deflection nozzles are considered. The admissible norm of watering by overhead irrigation of sandy loam soils and the scheme of a complete set of the FREGAT Sprinkling System deflection nozzles for VOLZHNIGIM design is defined.
