Book Synopsis Applications in Water Systems Management and Modeling by : Daniela Malcangio
Download or read book Applications in Water Systems Management and Modeling written by Daniela Malcangio and published by BoD – Books on Demand. This book was released on 2018-05-02 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growth of urbanization, industrialization, and intensive agricultural practices, all superficial, inland, and marine water bodies have become the repository for large quantities of every type of substance extraneous to the natural aquatic environment. The knowledge of hydrodynamics becomes crucial in this context, as it is the driving mechanism for the movement and transport of these matters and of sediments that become collectors of these substances, in a surface water system. The best way to understand these natural processes is via examples and case studies. This book deals with practical studies of hydrodynamic processes through physical and numerical models. Researchers, together with practicing engineers, will find this book useful in making a rapid assessment of different environmental water body problems.
Book Synopsis Application of a Hydrodynamic and Water Quality Model for Inland Surface Water Systems by : Lubo Liu
Download or read book Application of a Hydrodynamic and Water Quality Model for Inland Surface Water Systems written by Lubo Liu and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter introduces basic concepts, properties, and principles of different processes in inland surface water and analytical methodologies. The fundamentals of surface water hydrodynamics, including water properties, hydrodynamic processes, Cartesian coordinate-based governing equations, and boundary and initial conditions were reviewed. The fate and transport of contaminants in surface water were introduced. Based on aforementioned theory and principles, two hydrodynamic-water quality models were developed for studying a lake and a river, respectively. A stratified 3D model was used to investigate the circulation and E. coli transport in the nearshore region of Lake Michigan. The modeling results show that stratified phenomenon exists in the near region, and a 3D model is necessary even though a previous 2D model works well for the shallow water environment. A 2D depth-averaged water quality model was developed to estimate the fate and transport of four contaminants in the San Joaquin River of California. The modeling results indicate that it took 20 days for these contaminants to transport from the upstream to the downstream in the research domain. These models can be effectively used for inland surface water restoration and management.

Download or read book Environmental Impact Research Program: Coupling Hydrodynamics to a Multiple-Box Water Quality Model written by Sandra L. Bird and published by . This book was released on 1988 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term, multidimensional water quality modeling, using directly linked hydrodynamic and water quality models, can become prohibitively expensive. In this report, fine scale, short time-step hydrodynamic model output is linked with coarse grid, longer time-step multiple-box water quality model. The formulation, limitations, and adaption for use in applications of the Water Quality Analysis Simulation Program (WASP), the US Environmental Protection Agency multiple-box model, are discussed. Linkage of the multiple-box model to two hydrodynamic models is explained. Dye tracer simulations are used to compare mass transport by the box model with mass transport by the directly linked models for three applications: Savannah River Estuary, Mississippi Sound, and DeGray Lake. Keywords: Numerical methods.
Book Synopsis Linked Hydrodynamic and Biogeochemical Models of Water Quality in Shallow Lakes by : Peter Shanahan

This book was released on 1982 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approaches to lake water quality modeling are critically examined with particular attention to the formulation of water quality transport as the link between hydrodynamics and biogeochemical reaction. A linked water quality model for shallow lakes includes three major components: a biogeochemical reaction component, a lake hydrodynamics component and a water quality transport component. State-of-the-art modeling approaches for each component are reviewed, and a synopsis of phosphorus dynamics in shallow lakes is given. For the water quality transport component, review of the literature shows two significantly different approaches to water transport: a lumped component approach based upon multiple fully-mixed boxes, and a continuum approach employing the finite difference method to approximate the continuous governing equations. The multiple-box model is shown in an analysis of the kindred fully-mixed tanks-in-series conceptual reactor model to create an excessive implicit dispersion due to its formulation. This leads to a model in which the model mass transport is not closely related to the properties of the physical system. being modeled. Rather, dispersive transport in the model is shown to depend heavily upon the model formulation -- the model transport parameters thus cannot be specified from hydrodynamic data but must be found by calibration. In direct contrast, the finite difference model maintains a far closer approximation to the physical system and permits direct specification of water quality transport from the actual lake hydrodynamics. To support these arguments, a computer program incorporating both a multiple-box model and an alternative one-dimensional finite difference model is developed and applied to Lake Balaton in Hungary. The biogeochemical component of both models is a four component phosphorus-phytoplankton interaction model originally proposed by van Straten (1980). Hydrodynamic information is supplied to the one-dimensional finite difference model by linkage to a transient two-dimensional single-layer model of wind-driven circulation. A one-dimensional dispersion coefficient is computed from the two-dimensional velocity field using a method based upon that of Fischer (1966, 1969) and Holley, Harleman and Fischer (1970), but proceeding from the assumption that advection rather than turbulent diffusion dominates lateral mixing. The finite difference model developed for Lake Balaton consists of forty grids and is used to simulate a representative period from early spring to late summer. The results are contrasted with those produced by a four-box model of the lake using long-term average advection and calibrated dispersive exchange flows. The finite difference model is found to lead to a predicted behavior more similar to that observed in field data collected from Lake Balaton. Experimentation with the models is conducted to examine the behavior of the lake and the dominant factors leading to that behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Schizophrenia may not be a single disease, but the result of a diverse set of related conditions. Modern neuroscience is beginning to reveal some of the genetic and environmental underpinnings of schizophrenia; however, an approach less well travelled is to examine the medical disorders that produce symptoms resembling schizophrenia. This book is the first major attempt to bring together the diseases that produce what has been termed 'secondary schizophrenia'. International experts from diverse backgrounds ask the questions: does this medical disorder, or drug, or condition cause psychosis? If yes, does it resemble schizophrenia? What mechanisms form the basis of this relationship? What implications does this understanding have for aetiology and treatment? The answers are a feast for clinicians and researchers of psychosis and schizophrenia. They mark the next step in trying to meet the most important challenge to modern neuroscience – understanding and conquering this most mysterious of human diseases.
