WebbIn this contribution, different 3D numerical approaches are applied in order to simulate the behaviour of turbulent flow through a rectangular channel with broad-crested weirs. In addition, water flow velocities, using Acoustic Doppler Velocimetry (ADV) instrumentation, were recorded. Two turbulence quantities are estimated using the laboratory records … WebbWeirs are to be evaluated using the following equation. Q 333 B H32 where Q is the water flow rate in ft3sec B is the length of the weir and the channel width in ft and H is the head over the weir in ft.
