Evaluation of viscous models for simulation of flow over round-shaped weirs
Original language description
In connection with the process of dam safety enhancement, emergency spillways of dams are being widely upgraded in Czech Republic. The aim is to enhance their capacity to satisfy the requirement for safety management of 10 000-year flood passage. Round-shaped weirs are often used for this purpose. They are easy to build, which is their main advantage. Round-shaped weirs were used for example in the reconstruction and capacity enhancement of the emergency spillway on the Bystřička dam or the Šance dam. The most important parameters of each spillway are its capacity and discharge coefficient. Hydraulic models are usually used to assess the capacity and discharge coefficient of given weir shape. However, numerical simulations are taking place here too. A2D numerical simulation of flow over round-shaped weir was performed in combination with nine viscous models. The aim of work is to find which viscous model is most suitable for simulating of flow over round-shaped weirs. All computations
