The paper deals with research focused on description of flow structure in front of broad-crested weir. Based on experimental measurement, the flow structure in front of the weir (the recirculation zone of flow and tornado ...

Full-width sharp-edged broad-crested rectangular weirs in the range 0.1 < h/L <= 0.3 situated in rectangular channels are frequently used in submerged flow conditions. To determine the discharge for the submerged flow, ...

In the case of flow over rectangular broad-crested weir, where the inflow is realized by approach shaft, occurs influence of water surface level by approach flow velocity. The paper describes numerical model of flow including ...
