 In the case of flow over rectangular broad-crested weir, where inflow is realized by approach shaft, occurs influence water surface level velocity. The paper describes numerical model including and outlet shaft. Simulations were created 2D 3D with using three methods turbulent modelling. this a for each setup evaluated then it compared measured values.

Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purp...
