This book was released on 2003 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To better understand the impact of Grand River plume on the surrounding receiving waters, a combined observational and modeling study of the Grand River plume transport in the eastern basin of Lake Erie has been conducted for late spring of 2001 using a high resolution depth-integrated nonlinear barotropic finite element model. Due to the lack of observations needed for specifying the open boundary conditions, an extended domain of receiving waters with closed boundary was applied in this numerical study"--Abstract.
Download or read book Phosphorus Along the Soil Freshwater Ocean Continuum written by Barbara J. Cade-Menun and published by Frontiers Media SA. This book was released on 2019-05-15 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential element for all organisms. However, there is a P paradox, whereby P concentrations considered deficient in some environments such as in agricultural soils are considered excessive in water, where they trigger eutrophication. Ensuring adequate P for crop production while minimizing water quality degradation requires consideration of the P continuum from soils to freshwater and oceans. It also requires an international, interdisciplinary approach to monitoring and scientific research. This eBook brings together P studies in soil science, lakes, rivers, estuaries and oceans, with 74 authors from 12 countries in Asia, Europe and North America. The papers assembled here provide important new information to address knowledge gaps, cover P forms and cycling in soil and water, and identify key priorities for future research. Thus, the papers assembled here provide current and interdisciplinary information about P forms and their cycling along the soil-freshwater-ocean continuum, which is essential for environmentally sustainable P use.
Download or read book Dynamics and Numerical Modeling of River Plumes in Lakes written by Navid Nekouee and published by . This book was released on 2010 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Models of the fate and transport of river plumes and the bacteria they carry into lakes are developed. They are needed to enable informed decisions about beach closures to avoid economic losses, and to help design water intakes and operate combined sewer overflow schemes to obviate exposure of the public to potential pathogens. This study advances our understanding of river plumes dynamics in coastal waters by means of field studies and numerical techniques. Extensive field measurements were carried out in the swimming seasons of 2006 and 2007 on the Grand River plume as it enters Lake Michigan. They included simultaneous aerial photography, measurements of lake physical properties, the addition of artificial tracers to track the plume, and bacterial sampling. Our observed results show more flow classes than included in previous studies (e.g. CORMIX). Onshore wind can have a significant effect on the plume and whether it impacts the shoreline. A new classification scheme based on the relative magnitude of plume-crossflow length scale and Richardson number based on the wind speed is devised. Previous studies on lateral spreading are complemented with a new relationship in the near field. The plume thickness decreased rapidly with distance from the river mouth and a new non-dimensional relationship to predict thickness is developed. Empirical near field models for surface buoyant plumes are reviewed and a near field trajectory and dilution model for large aspect ratio surface discharge channels is devised. Bacterial reductions due to dilution were generally small (less than 10:1) up to 4.5 km from the river mouth. E. coli decay rates were significantly affected by solar radiation and ranged from 0.2 to 2.2 day-1 which were within the range of previous studies in Lake Michigan. Total coliform survived longer than E. coli suggesting different die-off mechanisms. Mathematical models of the bacterial transport are developed that employ a nested modeling scheme to represent the 3D hydrodynamic processes of surface river discharges in the Great Lakes. A particle tracking model is used that provides the capability to track a decaying tracer and better quantify mixing due to turbulent diffusion. Particle tracking models have considerable advantages over gradient diffusion models in simulating bacterial behavior nearshore that results in an improved representation of bacteria diffusion, decay and transport. Due to the complexity and wide variation of the time and length scale of the hydrodynamic and turbulent processes in the near field (where plume mixing is dominated by initial momentum and buoyancy) and far field (where plume mixing is dominated by ambient turbulence), a coupling technique is adapted. The far field random walk particle tracking model incorporates the empirical near field model. It simulates the transport, diffusion and decay of bacteria as discrete particles and employs the near field output as the source and transports the particles based on ambient currents predicted by the 3D hydrodynamic model. The coupled model improves dilution predictions in the near field. The new techniques advance our knowledge of the nearshore fate and transport of bacteria in the Great Lakes and can be ultimately applied to the NOAA Great Lakes Coastal Forecasting System to provide a reliable prediction tool for bacterial transport in recreational waters."--Summary.

Available in PDF, EPUB and Kindle. Book excerpt: Learn about the wonders of Lake Erie and Lake St. Clair in this fascinating and readable book. The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers—anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region—the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: • how Lake Erie was formed through glacial processes • why daily and seasonal weather patterns occur • causes of the water currents and waves • causes of temperature patterns in the lakes • the location of productive reef features • the species of fish and birds found in the area • the importance of the wetlands • the effect of current and past pollution on the aquatic life in the lakes
Download or read book Ancient Monuments of the Mississippi Valley written by Ephraim G. Squier and published by Smithsonian Books. This book was released on 1998 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1848 as the first major work in the nascent discipline as well as the first publication of the newly established Smithsonian Institution, Ancient Monuments of the Mississippi Valley remains today not only a key document in the history of American archaeology but also the primary source of information on hundreds of mounds and earthworks in the eastern United States, most of which have now vanished. Despite adhering to the popular assumption that the moundbuilders could not have been the ancestors of the supposedly savage Native American groups still living in the region, the authors set high standards for their time. Their work provides insight into some of the conceptual, methodological, and substantive issues that archaeologists still confront. Long out of print, this 150th anniversary edition includes David J. Meltzer's lively introduction, which describes the controversies surrounding the book’s original publication, from a bitter, decades-long feud between Squier and Davis to widespread debates about the links between race, religion, and human origins. Complete with a new index and bibliography, and illustrated with the original maps, plates, and engravings, Ancient Monuments of the Mississippi Valley provides a new generation with a first-hand view of this pioneer era in American archaeology.

Available in PDF, EPUB and Kindle. Book excerpt: A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.
Download or read book Circulation in the Coastal Ocean written by G.T. Csanady and published by Springer Science & Business Media. This book was released on 1982-09-30 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some time there has existed an extensive theoretical literature relating to tides on continental shelves and also to the behavior of estuaries. Much less attention was traditionally paid to the dynamics of longer term, larger scale motions (those which are usually described as circulation') over continental shelves or in enclosed shallow seas such as the North American Great Lakes. This is no longer the case: spurred on by other disciplines, notably biological oceanography, and by public concern with the environment, the physical science of the coastal ocean has made giant strides during the last two decades or so. Today, it is probably fair to say that coastal ocean physics has come of age as a deduc tive quantitative science. A well developed body of theoretical models exist, based on the equations of fluid motion, which have been related to observed currents, sea level variations, water properties, etc. Quantitative parameters required in using the models to predict e.g. the effects of wind or of freshwater influx on coastal currents can be estimated within reasonable bounds of error. While much remains to be learned, and many exciting discoveries presumably await us in the future, the time seems appropriate to summarize those aspects of coastal ocean dynamics relevant to 'circulation' or long term motion.
