Modelling of Flows and Sediment through Hydraulic Structures

The central concern of the book is to study flows and sediment phenomena through hydraulic structures in a regulated reservoir. The flow patterns in and around most hydraulic structures are complex, three-dimensional, and highly turbulent. For these reasons, in order to understand the impact of hydraulic structures on the hydrodynamic, sediment transport processes and morphological changes in regulated reservoirs it is often necessary to investigate these processes in three dimensions. In design a real and complex water regulated reservoir both physical and numerical models are applied. In the numerical sections, explain the governing equations of the hydrodynamic (including turbulence), sediment transport and morphodynamic process, respectively. Besides, mathematical solutions for the different equations are given in detail in a separate chapter. In next chapters, the capability of the numerical model is evaluated with two sets of experimental data. Also, one chapter presents the application of the numerical model to the experiment explained in physical modelling part and comparisons made between the physical and numerical model results. Final chapter summarises the main findings.
