Flow measurement in open channels can be performed using a variety of devices such as multi-shaped weirs or hydraulic jump flow meters. Most of them have a sill at which solid deposits can accumulate. Self-Cleaning devices are those with a flat bottom whi... see more
The rectangular weirs with and without lateral contraction are theoretically examined, more particularly their discharge coefficient. Under the realistic assumption of a critical state at the location of the weir, the application of the energy equation be... see more
