The practical weir is common discharge control structure of spillway
and its head loss is an important parameter for calculating the spillway discharge capacity and the water surface line
as well as for the design of energy dissipator. The empirical formula for calculating head loss recommended by cur ⁃ rent specifications has low accuracy. Therefore
using the hydraulic boundary layer theory to derive the calculation formula of head loss of practical weir in spillway is of practical significance.
