Sediment Transport Dynamics

Sediment Transport Dynamics

This book focuses on the fundamentals of sediment transport in surface waters. It covers sediment properties open channel flows sediment particle settling incipient motion bed forms bed load suspended load total load cohesive sediments water-sediment two-phase flows hyperconcentrated flows debris flows wave-induced sediment transport turbidity currents and physical modeling. Besides the primary context of river sedimentation this book extensively covers sediment transport under coexisting waves and currents in coasts and estuaries hyperconcentrated and debris flows in rivers as well as turbidity currents in lakes reservoirs channels and the ocean. It includes a chapter on the water-sediment two-phase flow theory which is considered the basis of many sediment transport models. It introduces some special topics have that emerged in recent years such as the transport of mixed cohesive and noncohesive sediments biofilm-coated sediments and infiltrated sand within gravel and cobble beds. The text merges classical and new knowledge of sediment transport from various sources in English and non-English literature and includes important contributions made by many scientists and engineers from all over the world. It balances the breadth depth fundamental importance practical applicability and future advancement of the covered knowledge and can be used as a text and reference book. The chapters are arranged in a useful sequence for teaching purposes. Certain homework problems are prepared which also highlight the important topics for instructors to select.

Modelling and Analysis of Fine Sediment Transport in Wave-Current Bottom Boundary Layer

Modelling and Analysis of Fine Sediment Transport in Wave-Current Bottom Boundary Layer

The evolution and utilization of estuarine and coastal regions are greatly restricted by sediment problems. This thesis aims to better understand fine sediment transport under combined action of waves and currents especially in the wave-current bottom boundary layer (BBL). Field observations experimental data analysis theoretical analysis and numerical models are employed. Silt-dominated sediments are sensitive to flow dynamics and the suspended sediment concentration (SSC) increase rapidly under strong flow dynamics. This research unveils several fundamental aspects of silty sediment i. e. the criterion of the incipient motion the SSC profiles and their phase-averaged parameterization in wave-dominated conditions. An expression for sediment incipient motion is proposed for silt-sand sediment under combined wave and current conditions. A process based intra-wave 1DV model for flow-sediment dynamics near the bed is developed in combined wave-current conditions. The high concentration layer (HCL) was simulated and sensitivity analysis was carried out by the 1DV model on factors that impact the SSC in the HCL. Finally based on the 1DV model the formulations of the mean SSC profile of silt-sand sediments in wave conditions were proposed. The developed approaches are expected to be applied in engineering practice and further simulation. | Modelling and Analysis of Fine Sediment Transport in Wave-Current Bottom Boundary Layer

Low Head Hydropower for Local Energy Solutions

Low Head Hydropower for Local Energy Solutions

The role of small hydropower is becoming increasingly important on a global level. Increasing energy demand and environmental awareness has further triggered research and development into sustainable low-cost technologies. In developing countries particularly in rural areas the possibility of local power generation could considerably improve living conditions. With this in mind the development of a next generation low-head hydropower machines was subject of investigation in the EU-project HYLOW. Being part of the research lines of that project this thesis presents a numerical modelling approach to improve the design of machines like water wheels for increased hydraulic efficiency. Nowadays Computational Fluid Dynamics (CFD) enables numerical models to be quite accurate and incorporate physical complexities like free surfaces and rotating machines. The results of the CFD simulations carried out in this research show that a change in blade geometry can result in higher torque levels thereby increasing performance. Numerical simulations also enabled to determine the optimal wheel-width to channel-width ratio and further improve performance by modifying the channel bed conditions upstream and downstream of the water wheel. With a power rating in the low kilowatt range low-head hydropower machines like optimised water wheels seem to have a clear potential for small-scale energy generation thereby contributing to achieving the Sustainable Development Goals by providing local energy solutions. | Low Head Hydropower for Local Energy Solutions
