Download or read book Subaqueous Mass Movements and Their Consequences written by A. Georgiopoulou and published by Geological Society of London. This book was released on 2020-07-08 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: This GSL volume focuses on underwater or subaqueous landslides with the overarching goal of understanding how they affect society and the environment. The new research presented here is the result of significant advances made over recent years in directly monitoring submarine landslides, in standardising global datasets for quantitative analysis, constructing a global database, and leading international research projects. This volume demonstrates the breadth of investigation taking place into subaqueous landslides, and shows that while events like the recent ones in the Indonesian archipelago can be devastating they are at the smaller end of what the Earth has experienced in the past. Understanding the spectrum of subaqueous landslide processes, and therefore the potential societal impact, requires research across all spatial and temporal scales. This volume delivers a compilation of state-of-the-art papers covering topics from regional landslide databases to advanced techniques for in situ measurements, to numerical modelling of processes and hazards.
Download or read book Reservoir Sedimentation written by Anton J. Schleiss and published by CRC Press. This book was released on 2014-08-12 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the mechanisms of reservoir sedimentation being well known for a long time, sustainable and preventive measures are rarely taken into consideration in the design of new reservoirs. To avoid operational problems of powerhouses, sedimentation is often treated for existing reservoirs with measures which are efficient only for a limited time.Th
Download or read book New Perspectives on Deep water Sandstones written by G. Shanmugam and published by Elsevier. This book was released on 2012-03-14 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs. Promotes pragmatic interpretation of deep-water sands using alternative possibilities Validates the economic importance of SMTDs and BCRS in deep-water exploration and production Rich in empirical data and timely new perspectives
Download or read book Turbidity Currents on the Ocean Bottom written by Lamont-Doherty Geological Observatory and published by . This book was released on 1970 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean bottom turbidity currents flow downslope, under the influence of gravity and by virtue of the fact that the density of their entrained turbulent suspension is greater than that of water. Turbidity currents originate in upslope sedimentary reservoirs. Initiated by some trigger mechanism, the sediment fails and starts to slump. As all or parts of the slump are transformed into a suspension of higher density than the surrounding water, a resulting turbidity current flows downslope with increasing velocity (often through channels) until it reaches lower gradients, where it further spreads out and decreases in velocity. The current can pick up new material from the sea bed in the path of motion if the velocity and turbulence are sufficient to retard the settling of entrained particles. Turbidity currents can flow for several thousand kilometers, moving out to the extremes of a sedimentary depression. As the current slackens, suspended sediment is deposited vertically and laterally in graded beds known as turbidites. Depending upon the properties of the initial suspension, the grain size of the entrained particles, and the steepeness of the downhill slope, the velocities of turbidity currents range from about 10cm/sec to over 50 knots (2,500 cm/sec). The basal portion of the average turbidite bed may be deposited on the basin floor in a few hours. (Author).
Download or read book Mass Transport Gravity Flows and Bottom Currents written by G. Shanmugam and published by Elsevier. This book was released on 2020-10-31 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass Transport, Gravity Flows, and Bottom Currents: Downslope and Alongslope Processes and Deposits focuses solely on important downslope and alongslope processes. The book provides clear definitions and characteristics based on soil mechanics, fluid mechanics and sediment concentration by volume. It addresses Slides, Slumps, and Debris Flows, Grain Flows, Liquefied/Fluidized Flows, and Turbidity Currents, Density plumes, Hyperpycnal Flows, the Triggering Mechanisms of Downslope Processes, Bottom Currents, and Soft-Sediment Deformation Structures. The mechanics of each process are described in detail and used to provide empirically-driven categories to help recognize these deposits it the rock record. Case studies clearly illustrate of the problems inherent in recognizing these processes in the rock record, and potential solutions are provided alongside future avenues of research. An appendix also provides step-by-step guidance in describing and interpreting sediments. Comprehensively addresses modern downslope and alongslope processes, including definitions and mechanisms Provides key criteria for the recognition of depositional facies in the rock record Includes case studies to illustrate each downslope and alongslope process Identifies key problems and potential solutions for future research Uses pragmatic, empirical, data-driven interpretations to revise conventional facies models

Download or read book Geological Processes on Continental Margins written by M. S. Stoker and published by Geological Society of London. This book was released on 1998 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continental margins form the relatively narrow transition zones between the different domains of land masses and deep-ocean basins. They are the main regions of sediment input and transfer of sediments to the oceans and thus represent important zones of sediment flux. This work addresses three topics of significance to continental margin development: sedimentation, mass-wasting and stability. It should be of interest to marine geologists, sedimentologists, palaeoceanographers and physical properties specialists.
Download or read book Contourites written by M. Rebesco and published by Elsevier. This book was released on 2008-11-25 with total page 793 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contourites are sediments deposited or substantially reworked by bottom currents. The study of contourites is crucial for several fields of fundamental and applied research: paleoclimatology and paleo-oceanography, since these fairly continuous and relatively high-resolution sediments hold the key for priceless information on the variability in circulation patter, current velocity, oceanographic history and basin interconnectivity; hydrocarbon exploration, since accumulation of source rocks may be favored by weak bottom currents, whereas "clean" deep-sea sands may be formed by robust flows; and slope stability, since low-permeability fine-grained contourites facilitate the formation of overpressurized gliding planes when fresh contourites with a high pore-water content becomes rapidly loaded, or when their rigid biosiliceous microfabric collapses due to diagenetic conditions. Despite its significance, this group of sediments is poorly known by the majority of non-specialists. Notwithstanding the growing interest and the intensified research in contourites, a textbook that might also serve as a reference book on contourites was missing until now. This book addresses all aspects of the knowledge in the field of contourites and provides an authoritative and comprehensive coverage of the subject. It also can serve as a standard reference work for non-specialists, and in particular postgraduate students, university teachers and lecturers, researchers and professionals who are seeking an authoritative source of information about contourites. Reviews both theoretical topics and case histories Provides practical advice on multidisciplinary research techniques Provides also nonspecialist users with an intuitively-accessible, cross-referenced, and comprehensive coverage of the knowledge in the field Provides a helpful tool for research in the preparation of classroom lectures
Download or read book Marine Biogeochemical Cycles written by Rachael James and published by Butterworth-Heinemann. This book was released on 2005 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Volume belongs to a series on Oceanography. It is designed so that it can be read on its own, or used as a supplement in oceanogrphy courses. After a brief introduction to sea-floor sediments, the book shows how the activities of marine organisms cycle nutrients and other dissolved constituents within the oceans, and influence the rates at which both solid and dissolved material is removed to sediments. It goes on to review the carbonate system and shows how sediments that come from continental areas may be transported to the deep sea, explores what sea-floor sediments have taught us about the history of the oceans, and describes the biological and chemical processes that continue long after sediments have been deposited on the deep sea-floor. * Covers the basics on the occurrence, distribution, and cycling of chemical elements in the ocean * Features full-color photographs and beautiful illustrations throughout * Reader-friendly layout, writing, and graphics * Pedagogy includes chapter summaries, chapter questions with answers and comments at the end of the book; highlighted key terms; and boxed topics and explanations * Can be used alone, as a supplement, or in combination with other Open University titles in oceanography
Download or read book Turbidity Currents and Sedimentation in Closed end Channels written by Chung-po Lin and published by . This book was released on 1986 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of concern over sedimentation and water quality in Closed-end channels such as docks, pier slips and residential canals, an investigation on the front behavior of turbidity currents and associated sedimentation in a closed-end channel was carried out. The focus of the present study was on the case of a closed'-end channel of rectangular cross section and horizontal bed connected orthogonally to a main channel, where turbulent flow and high suspension concentration existed. Experiments were conducted in two specially designed flume systems to investigate front characteristics of turbidity currents, flow regime, and sediment deposition. A group of dimensionless parameters for each physical aspect of concern derived from dimensional analysis provided the basis for selecting the measurement Items in laboratory experiments and for presenting tl-:e results.
