Sharp crested weirs and gates are flow measurement structures which are frequently used for discharge measurements in channels and laboratories. In this thesis, numerical modelling technique was used in the solution of two flow measurement problems, namely contracted sharp crested weirs (Problem 1) and combined weir and gate system (Problem 2). The numerical simulation of flow cases having similar conditions with the experiments from the previous studies is performed for both Problem 1 and 2. The basic flow...
Numerical modelling of contracted sharp-crested weirs and combined weir and gate systems
Altan Sakarya, Ayşe Burcu; Duru, Aysel (Wiley, 2020-05-01)
Discharge measurement and control structures are widely employed in hydraulic engineering applications. The objective of this study is to numerically investigate the modelling of two different structures, namely sharp-crested weirs as Problem 1 and combined weir and gate systems as Problem 2. The research methodology herein is based on the comparison of results of numerical simulations with experimental data for both problems separately. For the purpose of performing numerical simulations, the Reynolds-aver...
Numerical modeling of dam breach in concrete gravity dams

When a dam fails, a large amount of water is suddenly released that may create large flood waves capable of causing devastating impacts to downstream areas. This is even more important when the damage is caused by an earthquake, as it is unpredictable. The main objective of the research is a detailed simulating of the water surface profile from the first crack to the entire breaking of dams' body during earthquake using Finite Volume Method (FVM). The next objective is detecting of vulnerable zones on the d...

Numerical modeling of re-suspension and transport of fine sediments in coastal waters
Karadoğan, Erol; Özhan, Erdal; Department of Civil Engineering (2004)
In this thesis, the theory of three dimensional numerical modeling of transport and re-suspension of fine sediments is studied and a computer program is develped for simulation of the three dimensional suspended sediment transport. The computer program solves the three dimensional advection-diffusion equation simultaneously with a computer program prepared earlier for the simulation of three dimensional current systems. This computer program computes the velocity vectors, eddy viscosities and water surface ...
