Download or read book Development of an Atmospheric Dispersion Model for Heavier-Than-Air Gas Mixtures written by Jerry A. Havens and published by . This book was released on 1985 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modeling techniques use to predict atmospheric dispersion of heavy gases are reviewed and critiqued. These dispersion processes are characterized by three phases: (1) near field, negative buoyancy-domainated flow regime; (2) intermediate field, stably stratified shear flow regime; and (3) far field, passive turbulent diffusion regime. Mathematical models of laboratory and natural gravity currents are used to describe the negative buoyancy-dominated regime flow and dilution processes. A laboratory investigation of instantaneous heavy gas releases in calm air demonstrates scaling from small release volumes (0.5 cu m) to large field (2000 cu m) field releases, and is used to develop a mathematical model for the buoyancy-dominated regime. Laboratory data from stratified shear flow mixing experiments are used to develop a model for vertical diffusion of heavy gases in the atmospheric surface layer. The model concepts are consistent with the limiting passive behavior of demonstrated air pollution models. An interactive computer model for heavy gas dispersion (DEGADIS) is developed. The DEGADIS model accounts for the three regimes of heavy gas dispersion processes and can be used to simulate instantaneous, steady state, and transient releases. The model provides predictions of downwind concentration decay which are in good agreement with the full range of field experimental data currently available, and is recommended for incorporation in the Coast Guard hazard assessment computer system.

Book excerpt: Atmospheric transport and diffusion models have been developed for real-time calculations of the location and concentration of toxic or radioactive materials during an accidental release at the Savannah River Site (SRS). These models are based Gaussian distributions and have been incorporated into an automated menu-driven program called the WIND (Weather INformation and Display) system. The WIND system atmospheric models employ certain assumptions that allow the computations of the ground-level concentration of toxic or radioactive materials to be made quickly. Gaussian models, such as PF/PL and 2DPUF, suffer from serious limitations including the inability to represent recirculation of pollutants in complex terrain, the use of one stability class at a given time to represent turbulent mixing over heterogeneous terrain, and the use of a wind field computed at only one height in the atmosphere. These limitations arise because the fundamental conservation relations of the atmosphere have been grossly simplified. Three-dimensional coupled atmospheric-dispersion models are not limited by the over-simplifications of the Gaussian assumption and have been used in the past to predict the transport of pollutants in a variety of atmospheric circulations. The disadvantage of these models is that they require large amounts of computational time; however, technology has progressed enough so that real-time simulations of dispersion may be made. These complex models can be run in an operational mode so that routine forecasts of the wind field and particulate concentration can be made.

Available in PDF, EPUB and Kindle. Book excerpt: Presents a comprehensive account of current research on the chemistry and toxicology of cadmium in natural waters. Discusses the sources, distribution, and fate of cadmium in aquatic ecosystems, including coverage of the biocycling and exotoxicity of cadmium to materia and fresh water biota. A succinct review of the analytical chemistry of cadmium in natural waters is also included. The contributors emphasize general principles rather than comprehensive documentation, making this volume accessible to a wide audience. The technical information helps provide the scientific rationale needed in the continuing effort to establish water quality criteria and standards for cadmium.

This book was released on 2006-01-16 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex task. The aim of this book is to discuss fundamental questions of invasion ecology, such as why particular communities become more invasible than others, what the mechanisms of exclusion of native species by invaders are, and whether invasion can be predicted. In addition, agricultural practices influencing invasion, the environmental and economic costs of invasion as well as possible management strategies are discussed. Readers will get a unique perspective on invasion ecology through employing general principles of ecology to plant invasions.
