Coarse-Grained Deltas


Book Description

This Special Publication contains most of the contributions presented at the 1st International Workshop on Fan Deltas (1988) but also contains additional papers which make this particular volume a very well-rounded reference source for the advanced undergraduate/graduate student and the professional earth scientist concerned with sedimentology and petroleum geology. The papers describe the sedimentology and tectonic setting of this important depositional environment. Course-grained deltas, ranging from sand to gravelly, are fully covered and the main focus is on steep-face systems whose steep subaqueous slopes are dominated by high-energy processes. The volume includes case histories from around the world and throughout the book there is emphasis on the subaqueous realm of the delta face, its sedimentary processes and facies associations

Continental Margin Sedimentation


Book Description

This volume on continental margin sedimentation brings together an expert editorial and contributor team to create a state-of-the-art resource. Taking a global perspective, the book spans a range of timescales and content, ranging from how oceans transport particles, to how thick rock sequences are formed on continental margins. Summarizes and integrates our understanding of sedimentary processes and strata associated with fluvial dispersal systems on continental shelves and slopes Explores timescales ranging from particle transport at one extreme, to deep burial at the other Insights are presented for margins in general, and with focus on a tectonically active margin (northern California) and a passive margin (New Jersey), enabling detailed examination of the intricate relationships between a wide suite of sedimentary processes and their preserved stratigraphy Includes observational studies which document the processes and strata found on particular margins, in addition to numerical models and laboratory experimentation, which provide a quantitative basis for extrapolation in time and space of insights about continental-margin sedimentation Provides a research resource for scientists studying modern and ancient margins, and an educational text for advanced students in sedimentology and stratigraphy







Alluvial Sedimentation


Book Description

Most of the thirty-four papers contained in this Special Publication arise from the Fourth International Conference on Fluvial Sedimentology held in Spain in 1989. Sections deal with various aspects of sediment transport and hydraulics in flume experiments and modern rivers, the analysis of alluvial facies, geomorphic and structural controls on alluvial sedimentation, alluvial stratigraphy and basin analysis, and finally the exploration and exploitation of ores. A professional reference to the most recent research in fluvial sedimentology. An international expert authorship.

Modeling of Hydrodynamics and Sediment Transport in the Mekong Delta


Book Description

This research aims to investigate the prevailing sediment dynamics and the sediment budget in the Mekong Delta by using a process-based model. Understanding sediment dynamics for the Mekong Delta requires high resolution analysis and detailed data, which is a challenge for managers and scientists. This study introduces such an approach and focuses on modeling the entire system with a process-based approach with Delft3D-4 and Delft3D Flexible Mesh (DFM). The first model is used to explore sediment dynamics at the coastal zone. The latter model allows straightforward coupling of 1D and 2D grids, making it suitable for analyzing the complex river and canal network of the Mekong Delta. The validated model suggests that the Mekong Delta receives ~99 Mt/year sediment from the Mekong River. This is much lower than the common estimate of 160 Mt/year. Only about 23% of the modelled total sediment load at Kratie is exported to the sea. The remaining portion is trapped in the rivers and floodplains of the Mekong Delta. The results advance understanding of sediment dynamics and sediment budget in the Mekong Delta. As such the model is an efficient tool to support delta management and planning.




Geology for Engineers and Environmental Scientists


Book Description

The fourth edition of Geology for Engineers and Environmental Scientists provides students with a basic foundation in the principles of geology, along with an illustration of how engineers must design and build their projects with natural geologic materials and protect them from potentially hazardous geologic processes. Kehew introduces engineering topics including soil and rock mechanics with a quantitative approach that will give students a head start in more advanced engineering courses. The book is prefaced with a discussion of engineering and environmental challenges that our society must face in the current century, such as population growth, scarcity of water and mineral resources, transition to renewable energy, and effects of climate change. Numerous examples of engineering and environmental applications ranging from short descriptions to extensive case histories, such as the “Big Dig” in Boston to the effects of Hurricane Katrina and reconstruction afterward, are included in every chapter. A full chapter is devoted to subsurface contamination and cleanup technologies. For the first time, a large color insert will highlight geological features in the field.




Wave-Forced Sediment Erosion and Resuspension in the Yellow River Delta


Book Description

This book focuses on the phenomenon of sediment erosion and resuspension in the Yellow River delta, China, which is a vital issue involved in understanding the sediment transport processes in estuarine and coastal environments, and how these contribute to the nature and distribution of geohazards in the subaqueous Yellow River delta and Bohai Sea. The most important sections of this book will be the detailed physical mechanisms and theoretical models of sediment erosion and resuspension problem fully considering the wave-induced seabed dynamic response to waves, which are particularly useful for postgraduate students and junior researchers entering the discipline of estuary and coastal sedimentation, marine geotechnical engineering, estuary and coastal engineering, harbor and waterway engineering and coastal environmental protection. This book can also serve as a textbook for advanced graduate students of Marine Engineering Geology and Estuarine Sediment Dynamics.
