DESIGN OF NUMERICAL MODEL FOR OPTIMIZATION OF PUMPING STATION’S OPERATIONAL REGIME IN DRAINAGE CANAL SYSTEMS OF THE EASTERN SLOVAK LOWLAND. Drainage channel systems of lowlands regions are equipped by controllable regulating elements (pumping stations, sluice gates) in order to fulfill their function. Controllable regulating elements support the runoff of drainage waters into the recipient as well as increase the effectiveness of water management system in the territory. The design of drainage structures and their operational schedules were based on the simplified theory of steady flow and the assumption of the regular maintenance of channels, but the operational staff’s and researcher’s experiences refer to the low effectiveness of system operation due to insufficient longitudinal slope of channels and the high value of channel roughness as well as the schematized operational regime design. The aim of the article is to design of numerical model of 1D unsteady flow for improvement of pumping station’s operational regime in the drainage canal system. The model is based on Saint-Venant equations which are solved by means of the implicit Preissmann scheme and was verified by laboratory experiments on physical hydraulic model. By numerical model optimized operating regime especially at higher hydraulic roughness of channel reduces a number of manipulations with pumps and extends their operation time.
