Book Description
The practical engineer looking for an urgent solution to a sediment-related project often finds that the results of the relevant academic research are published in unfamiliar language in publications that are not easily available. Dynamics of marine sands bridges the gap between academic research and practical applications by summarising the research results in a unified form, backed up with worked examples and case studies. This comprehensive new book presents methods for calculating the various hydrodynamic and sediment dynamic quantities necessary for marine sediment transport applications, and recommends the most appropriate methods to use for engineering projects.

Book Description
Scour is the primary cause of bridge failures in the United States and accurate field-scale simulations of scour are required for bridge stability analysis. In current bridge design practice, empirical equations based on laboratory flume tests are utilized to determine scour depth. These equations have been proven to be conservative due to scale effects when applied to field-scale scour conditions. Therefore, computational fluid dynamics (CFD) solvers have been utilized to simulate flow behavior around bridge piers. However, the majority of current CFD solvers do not accurately estimate the large-scale scour depth in field conditions, and mass conservation during scour is typically not satisfied. Therefore, a new CFD solver is proposed in this dissertation with new features including a moving-bed, cut-cell model, and mass-conservative sediment transport. The new moving-bed cut-cell model is based on a Cartesian grid system in the vertical coordinate (z-coordinate), and the bed depth is defined at vertices of the unstructured horizontal mesh. This discourages discontinuities in the bed and allows a more accurate representation of the bathymetry. The new model ensures that the total sediment mass within the bed and flow is conserved during bed movement and sediment transport. The proposed three-dimensional (3D), moving-bed and mass-conserved CFD solver has been applied to various scour studies and validated with flume tests in terms of flow velocity and scour patterns. The moving-bed cut-cell model provides accurate, continuous, and smooth simulation of the flow field and scour patterns and has been validated with the results of several experiments.

Book Description
This textbook explores both the theoretical foundation of the Finite Volume Method (FVM) and its applications in Computational Fluid Dynamics (CFD). Readers will discover a thorough explanation of the FVM numerics and algorithms used for the simulation of incompressible and compressible fluid flows, along with a detailed examination of the components needed for the development of a collocated unstructured pressure-based CFD solver. Two particular CFD codes are explored. The first is uFVM, a three-dimensional unstructured pressure-based finite volume academic CFD code, implemented within Matlab. The second is OpenFOAM®, an open source framework used in the development of a range of CFD programs for the simulation of industrial scale flow problems. With over 220 figures, numerous examples and more than one hundred exercise on FVM numerics, programming, and applications, this textbook is suitable for use in an introductory course on the FVM, in an advanced course on numerics, and as a reference for CFD programmers and researchers.

Book Description
With surveyed full-scale bathymetries of the Feather River Bridge, this hybrid approach and the decay function were applied to study the pier scour problem. The decay trend and the envelope decay function were verified with the results of CFD modeling for the full-scale models. Using the soil composition of each layer, the application of the decay function was preliminarily developed.
