This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to give an introduction to the most important aspects of suspended matter in the aquatic environment: its origin and composition, the concentration distribution, transport and deposition, and the most important physical-chemical-bio logical process that affects suspended matter: flocculation. In Chap ter 1 the development of suspended matter observation and study throughout history is given, with the coming of a more modern approach during the 19th century and the first half of the 20th century, and the development of the present science of suspended matter after 1945. The sources of suspended matter in rivers, lakes, estuaries, and the sea are discussed in Chapter 2, which includes the supply of detrital particles as well as the formation of new particles in the water (organic matter, carbonate, opal). The concentration distribution of suspended matter in rivers, lakes, estuaries, tidal is discussed in Chapter 3, to which is areas, lagoons, and in the sea added a discussion on the sampling of suspended matter and on methods to determine its concentration. Particle composition is treated in Chapter 4, to which is added a section (4. 6) on the compositional analysis of suspended particles. Also included is a discussion on particle surface characteristics and the adsorption of elements and compounds onto particles.

Available in PDF, EPUB and Kindle. Book excerpt: Suspended mud delivered to coastal zones typically deposit as flocculated aggre- gates. This study aims to better understand how the flocculation process alters the size and properties of flocs in the unsteady turbulent shear conditions found in fluvial to marine transitions using a combination of laboratory and numerical experiments. The first set of experiments examines the impact of repeat exposure to multiple cycles of high and low shear rate on the process of flocculation (similar to cyclic tidal zones). To do this, a suspension of kaolinite and montmorillonite is introduced to a mixing chamber and allowed to flocculate under relatively low turbulent shear. Flocs are allowed to grow until an equilibrium size is reached. Following this, the suspension is deflocculated with vigorous mixing, and then reflocculated under the lower shear condition. This cycle is repeated seven times. The primary findings are that the equilibrium floc size is not dependent on the number of deflocculation and reflocculation cycles, whereas the floc growth rate up to equilibrium is. The second set of experiments examines continual shear-rate reduction on the evolution of flocs prior to reaching equilibrium (similar to river mouth jets and plumes). Flocs in these experiments do not form from primary particles under steady- state shear. Instead, at each successive shear rate, they grow from where they left off under the previous condition. Following this decay and growth of flocs, the shear rate is increased in a stepwise manner to examine breakup behavior. Results highlight how significantly floc settling velocity can change in such transitional conditions, sug- gesting that a static settling velocity might not be appropriate in fluvial to marine transitions. Data from these experiments are also useful for testing the ability of floc models developed from steady-state experiments to handle more natural unsteady conditions. The time-dependent mean floc size model of Winterwerp (1998) is used to model the data from both sets of experiments. An improvement to the Winterwerp model is proposed to better predict the reduction in growth rate that occurs as flocs ap- proach the equilibrium condition. The improvement comes through size-dependent aggregation and breakup coefficients.

Available in PDF, EPUB and Kindle. Book excerpt: The interface of 440,000 km long coastline in the world is subject to global change, with an increasing human pressure (land use, buildings, sand mining, dredging) and increasing population. Improving our knowledge on involved mechanisms and sediment transport processes, monitoring the evolution of sedimentary stocks and anticipating changes in littoral and coastal zones is essential for this purpose. The special issue of Water on “Sediment transport in coastal waters” gathers thirteen papers which introduce the current revolution in the scientific research related to coastal and littoral hydrosedimentary dynamics, and reflect the diversity of concerns on which research in coastal sediment transport is based, and current trends — topics and preferred methods — to address them.

Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly urbanized world, water systems must be designed and operated according to innovative standards in terms of climate adaptation, resource efficiency, sustainability and resilience. This grand challenge triggers unprecedented questions for hydro-environment research and engineering. Shifts in paradigms are urgently needed in the way we view (circular) water systems, water as a renewable energy (production and storage), risk management of floods, storms, sea level rise and droughts, as well as their consequences on water quality, morphodynamics (e.g., reservoir sedimentation, scour, sustainability of deltas) and the environment. Addressing these issues requires a deep understanding of basic processes in fluid mechanics, heat and mass transfer, surface and groundwater flow, among others.

Available in PDF, EPUB and Kindle. Book excerpt: In Physical Processes in Estuaries the present day knowledge of the physics of transport phenomena in estuaries and their mathematical treatment is summarized: It is divided into following parts: - Water movements in estuaries - Estuarine fronts and river plumes - Internal waves and interface stability - Fine sediment transport, aggregation of particles, settling velocity of mud flocs - Sedimentation and erosion of fine sediments. For each topic an up-to-date review and recommendations for future research are given, followed by results of original studies. Since estuarine environments are the first to be threatened by urbanization and industrial exploitation this book is an important tool for students and researchers of environmental problems as well as for consultants and water authorities.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied. Having worked extensively in academia and industry, the Editor-in-Chief has been careful about constructing a work for a shared audience and cause
