Originální abstrakt

Weirs belong to one of most common water structures. Various shapes of weirs are used at various conditions (e.g. emergency spillway, river weir, volumetric weir, etc.). For estimation of the weir capacity and determination of discharge coefficient the physical modelling is usually performed. Recently, numerical simulations take place here too. The main advantages of numerical simulation compared to hydraulic research are the volume of information gained, relatively lower price, and no scale effects. However, results from simulations are strongly affected by the computation setup. The choice of turbulence model belongs to most important options. Within this study the flow over weir was simulated with nine turbulence models with the aim to find the most suitable one. All simulations were compared with results from hydraulic research.
