Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of fine-grained sediment flocculation is well recognized in the marine and estuarine environments but flocculation in freshwater fluvial systems requires further examination. Because flocculation is known to affect sediment settling velocities, this phenomenon has important environmental implications from a sediment and contaminant transport perspective. The suspended sediment characteristics of Oakville Sixteen-Mile Creek in southern Ontario were examined using a new digitizing method developed for the study. The study examined whether flocculation was present in the freshwater fluvial system; how stable the flocs within the realms of the sampling and analytical method were; and whether flocculation was influenced by temporal and spatial trends for the independent variables of temperature, pH, conductivity, suspended solid concentrations, discharge (turbulence), bacterial densities associated with suspended solids, particulate organic carbon, and major ions.

Available in PDF, EPUB and Kindle. Book excerpt: Fine-grained sediment flocculation is a phenomenon which is not fully understood in the freshwater fluvial environment. This study examined the suspended sediment characteristics of a southern Ontario river in order to determine the nature of flocculated suspended sediment and the factors which may influence it. It is the first research to quantify flocculation as the primary mode of transport for fine-grained mineral sediment in a river. As flocculation is known to alter the settling characteristics of particles, and potentially their ability to transport contaminants, there are important practical environmental consequences for flocculation in rivers.

Download or read book Flocculation in Natural and Engineered Environmental Systems written by Steven N. Liss and published by CRC Press. This book was released on 2004-12-28 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: While new developments in genomics, nanotechnology, sampling, and modelling permit increasingly revealing investigation into flocculation structure and processes, there is still a fundamental lack of knowledge related to many aspects of this phenomenon. Presented by a prominent team of international experts, this text takes a unique perspective and melds together the natural and engineering fields of science as they relate to this central phenomenon. In doing so, the authors present the full range of sampling, handling, analytical, and interpretive options for operational management of natural or engineered system, providing comprehensive coverage that meets the needs of researchers, practitioners and students.

Available in PDF, EPUB and Kindle. Book excerpt: To improve the understanding of the significance of flocculation in the fluvial environment, suspended particle characteristics of Oakville Sixteen-Mile Creek were studied to develop a non-destructive, direct observation method for determining floc characteristics such as equivalent spherical diameter, surface area, perimeter, and circularity; to determine the extent to which flocculation is present in the freshwater fluvial system; to determine the stability of flocs; and to establish the advantages and disadvantages of the sampling and analytical method. The method used involved collecting a water sample into a settling chamber where the suspended solids settle under gravity onto an inverted microscope slide. The slide is then placed on an inverted microscope and photographs of the flocs are taken through the microscope. The transparencies are rear- projected onto a translucent digitizer to obtain digital output.

Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!
