0184 Overflow Weir Profile UFT-FluidWing
Intended Purpose
According to several technical guidelines in Gemany and other countries, overflow weirs at CSO tanks should be equipped with monitoring devices in order to measure and record the overflow activity into the water bodies. In addition to the overflow duration and frequency, the determination of the annual overflow volume in m³/a is often required.
In our hydraulic laboratory, we have developed a combination of a new type of overflow spillway profile and a scum board, that provides accurate and hysteresis-free flow characteristics, even for a very low overflow head. Ventilation of the underside of the jet is not necessary.
