Available in PDF, EPUB and Kindle. Book excerpt: A set of solutions to the cohesive soil erosion problem were developed through this study. A first device, the Erosionometer, was developed to perform a quick and reliable test to determine the critical shear stress of soils. The Erosionometer is based on physical shearing of the soil surface and has been calibrated through comparison with piston flume measurements of critical shear stress for entrainment of various fluvial bed sediments. This device is portable, easy to deploy in the field and in the laboratory and allows engineers and researchers to cover a sizeable terrain by performing many tests in a short timeframe, with immediate results. A modification to the Erosionometer was made to allow for subjecting the soil sample to a pressure differential while testing for critical shear stress. The added functionality is intended for investigating the effect of pressure gradient on the erodibility of cohesive soils by allowing for the erosion test to be conducted under a high pressure head while the other face of the sample (away from the flow) is maintained at zero head. Testing demonstrated that a positive pressure gradient on the eroding side (high pressure on flow side) can significantly increase the critical shear stress of cohesive soils, which is in line with other research available in the literature. The results show a simple linear relation between pressure differential and critical shear stress. Practical implications of these results are discussed. A second device, the Erosion Rate Meter, or ERM, was developed to test cohesive soil samples to determine the rate of erosion under various levels of bed shear stress. This device, while being portable and fast to setup and run, is a very realistic simulation of the flow-bed interaction and allows for a direct measurement of bed shear stress on the soil sample and a precise measurement of the erosion rate. An obvious outcome of using the ERM is the easy development of erosion rate vs. bed shear stress relationships or models to characterize the different soils for design projects or further research. Of the 16 tested cohesive soils, all but two demonstrated a linear relation between erosion rate and bed shear stress. The testing systems and methods developed in this research provide a comprehensive solution to the erodibility of cohesive soils from investigation to design. Significant improvements are achieved over existing systems in the speed, reliability, accuracy, and cost of estimating the erodibility of cohesive soils.

This book was released on 2004-08-20 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the physical processes of cohesive sediment in the marine environment. It focuses on highly dynamic systems, such as estuaries and coastal seas. Processes on the continental shelf are also discussed and attention is given to the effects of chemistry, biology and gas.The process descriptions are based on hydrodynamic and soil mechanic principles, which integrate at the soil-water interface. This approach is substantiated through a classification scheme of sediment occurrences in which distinction is made between cohesive and granular material. Emphasis is also placed on the important interactions between turbulent flow and cohesive sediment suspensions, and on the impact of flow-induced forces on the stability of the seabed. An overview of literature on cohesive sediment dynamics is presented and a number of new developments are highlighted, in particular in relation to floc formation, settling and sedimentation, consolidation, bed failure and liquefaction and erosion of the bed. Moreover, it presents a summary on methods and techniques to measure the various sediment properties necessary to quantify the various parameters in the physical-mathematical model descriptions. A number of examples and case studies have been included.

Available in PDF, EPUB and Kindle. Book excerpt: Muddy coasts are land-sea transitional environments commonly found along low-energy shorelines which either receive large annual supplies of muddy sediments, or where unconsolidated muddy deposits are being eroded by wave action.In providing 21 case studies in different parts of the world this book provides an up-to-date review of the state of the art in muddy coast research. Issues dealing with hydrodynamics and suspended matter transport, erosion, deposition, and sediment budgets on tidal flats, primary production, nutrient fluxes and mineralization in lagoons are treated in a multi disciplinary manner. Most articles deal with issues which are of relevance with respect to global warming and future sea level rise.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Special Reference to Physical Processes in Estuaries is briefly outlined in Chapter I. Here I wish to acknowledge those whose support I consider to be pivotal to this under taking. My deepest appreciation goes to Cynthia Vey, whose organizational skills and dedicated effort made the completion of this volume possible. Thanks are also due to Gail Terry for workshop organization, Jean Branson for word processing and Lillean Pieter for helping with drawings. Finally, I must express my sincere appreciation to Arthur Ezra 9f the National Science Foundation for providing support (through Grant No. CEE-8401185) for the workshop, and to Hsiang Wang for depart mental encouragement. With deepest regret, I must note the untimely death of Ranjan Ariathurai, 39, on June 5, 1985, before this volume could be published. He was a guiding force to many within the small group of researchers in cohesive sediment dynamics, and his professional brilliance and inspirational personal qualities constituted the true spirit . behind the workshop. I trust this volume will serve, albeit in a small way, as a fitting memory to this spirit, and to the remarkable professional contributions Ranjan made during his short career. Professor Ray B.
