The effect of the energy head and the inlet and outlet key width on discharge coefficient of Piano key weir [PDF]

فناوری‌های پیشرفته در بهره‌وری آب, 2023
IntroductionPiano key weir is a form of nonlinear weir designed to improve the discharge capacity of spillway structures. Due to the increase in effective length, they can be used in dam spillways or water regulation structures.

Effect of Crest Roughness on Flow Characteristics over Circular Weirs [PDF]

Civil Engineering Infrastructures Journal, 2013
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.
