Study of hydrodynamic parameters of a self-operating sluge to prevent flood spills

All methods of combating the flooding populated areas are directly related to execution significant volumes earthworks, construction special structures, and therefore require comprehensive analysis substantiation selection most economically feasible affordable project options during design.But analyzing main protecting territory settlements from flooding, it should be noted that even with their optimal use, problem territories due river tributaries remains. Therefore, is worth focusing attention on search for a technical solution would make possible pump water tributary without using expensive, complex in design energy-consuming equipment. One promising solutions use automatic gateways.The purpose work study hydrodynamic parameters proposed self-acting lock prevent flood spills.The hydrotechnical structure (self-acting sluice spills) proposed, which designed spills can used regulate level hydraulic systems. It shown developed will significantly reduce negative consequences territories.A three-dimensional model was SolidWorks program confirm its performance sluice. The simulated simulation ejector FlowSimulation software module confirmed efficiency made determine distribution pressures fluid movement speeds it. established flow rate liquid flowing through cross-section pipeline intake 0.055 m3/s at speed 3 m/s.
