Experimental study of discharge Coefficient of Piano Key Side Weir in 45-Degree Sector of a curved channel [PDF]
مهندسی منابع آب, 2020 A new type of Long-crested weirs is Piano Key weir that allows the reservoir to run at a higher level. The use of a Piano Key weir as side weir allows for more drainage, due to the geometric shape of the channel and the impact of centrifugal force on the

Overflow Characteristic of Cylindrical Shape Crest Weirs Over Horizontal Bed
Tikrit Journal of Engineering Sciences, 2013 The most common types of weirs are the broad-crested weir, the sharp-crested weir, the circular crested weir and the ogee crested weir. Advantages of the cylindrical weir shape include the stable overflow pattern, the ease to pass floating debris, the ...

Discharge coefficient of flow over Al-Shalalat stepped weir on Al-Khusr River
Applied Water Science, 2021 Many hydraulic structures are constructed in an open channel according to the purposes and the nature of the region. Weir is one of these structures which is used for discharge measurements as well as rising water depth in irrigation channels.

Coefficients of Discharge of Submerged Sharp-crested weirs
Transactions of the Japan Society of Mechanical Engineers, 1953 According to our viewpoint that the submerged weirs will be a submerged orifice, we gave a formula of coefficient of discharge of submerged sharp-creasted weirs. The result was compared with those obtained by many methods, i.e., "du Buat", "Wisconsin", "Fteley & Stearns", "Francis", "Herschel" and "Bazin".

Engineering Reports, Volume 8, Issue 6, June 2026.A Richardson‐extrapolation–based mesh zoning framework is developed to optimize CFD simulation accuracy and computational efficiency in dam bottom outlet flows. Using six mesh scenarios and multi‐parameter convergence analysis (pressure, velocity, TKE), the method identifies an optimal fine‐resolution zone around the gate and progressively coarser ...

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Gravel‐bed rivers widen and narrow as bar‐push and bank‐pull wax and wane through individual floods, yet over decades the channel often holds near constant width, evidence of coupling between inner‐bank deposition and outer‐bank erosion. Because large, event‐scale data sets are scarce and most field rivers have mixed grain‐size beds, the ...
