Comment on doublelayer flip bucket structure in spillway having chute

Abstract

    Design flood discharge overflows with serial form filled body of water is steep, sloping end of a nasal spray depends several factors: flow removed, the steepness of slope, speed, depth and slope water flow last. Nasal spray structures that meet the selection requirements on technical and economic. In terms of hydraulics to ensure the main parameters: speed of the nasal spray while ensuring the long line of spray large but must be compatible with the material, the nasal spray pressure must be less than the value of negative pressure to not allow born nasal spray surface erosion and erosion pit depth should be smaller. There is no formula to calculate the nasal spray two-story, often through experimental models to determine the structure of nasal spray. Article mentioned a few initial findings about the nasal spray form of experiential two floors.
