Book Modelling of Pollutants in Complex Environmental Systems

Download or read book Modelling of Pollutants in Complex Environmental Systems written by Grady Hanrahan and published by ILM Publications. This book was released on 2010 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental modelling has enjoyed a long tradition, but there is a defined need to continually address both the power and the limitations of such models, as well as their quantitative assessment. This book showcases modern environmental modelling methods, the basic theory behind them and their incorporation into complex environmental investigations. It highlights advanced computing technologies and how they have led to unprecedented and adaptive modelling, simulation and decision-support tools to study complex environmental systems, and how they can be applied to current environmental concerns. This volume is essential reading for researchers in academia, industry and government-related bodies who have a vested interest in all aspects of environmental modelling. Features include: A range of modern environmental modelling techniques are described by experts from around the world, including the USA, Canada, Australia, Europe and Thailand; many examples from air, water, soil/sediment and biological matrices are covered in detail throughout the book; key chapters are included on modelling uncertainty and sensitivity analysis; and, a selection of figures are provided in full colour to enable greater comprehension of the topics discussed.

Book Contaminant Transport Modeling Through Saturated Porous Media

Download or read book Contaminant Transport Modeling Through Saturated Porous Media written by Anand M. Hulagabali and published by LAP Lambert Academic Publishing. This book was released on 2014-03 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater quality varies due to the chemical, geochemical, and biochemical reactions of the pollutants in the subsurface flow systems. To reliably predict the fate of contaminant transport in groundwater, an accurate numerical modeling is required. Analytical and numerical simulation models help civil engineering to understand the physical and chemical processes that influence contaminant transport through a saturated soil layer, including advective and dispersive transport as well as sorption.In the present investigation, An attempt has been made to provide a simple but sufficiently accurate methodology for numerical simulation of the one, two and three dimensional contaminant transport through the saturated homogeneous porous media and landfill liners using Finite Element method. Exercise was undertaken to determine the rate of movement of contaminants from landfill, so as to arrive at expected future concentrations of contaminants in the groundwater around landfill. Systematic study conducted to determine the impact of municipal solid waste disposal at Bhalaswa landfill Site in New Delhi has reveled that the groundwater is being significantly contaminated due to the leachate.

Book Centrifuge Modelling of Contaminant Transport Through Soils

Download or read book Centrifuge Modelling of Contaminant Transport Through Soils written by P. Rajeev Kumar and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indiscriminate land disposal of hazardous chemicals and industrial wastes, in the due course of time, causes contamination of the ground water regime as well as the subsurface soil layers. Various complex geo-chemical processes and mechanisms control the transport of these contaminants when they come in contact with the soil-water system.The transport of contaminants is often predicted with the help of mathematical models dealing with a set of governing equations, which are solved using either analytical or numerical methods. However, input parameters for these models can be obtained by conducting either controlled field experiments or laboratory column tests. To overcome the limitations associated with the laboratory and field scale experiments, geotechnical centrifuge modelling has been adopted by researchers and engineers. This book highlights such a research program conducted using a geotechnical centrifuge, and the instrumentation and the testing methodology adopted for monitoring contaminant transport through geotechnical centrifuge models. Also, it features, Finite Element modelling to valid the centrifuge test results. It may be a useful guide to an aspiring researcher.

Book Integration of Automatic Mesh Generation for Simulation of Contaminants in Soils and Groundwater

Download or read book Integration of Automatic Mesh Generation for Simulation of Contaminants in Soils and Groundwater written by and published by . This book was released on 1994 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automatic mesh generator was modified and implemented that conforms to arbitrarily shaped two dimensional geometries. The grid generator requires no user intervention and can handle multiple component systems. The routine is well suited to dynamic situations experiencing large geometrical change such as in solidification or ground freezing processes. Additionally, the system has the option to output its results in a 2D Groundwater Modeling System format and a 3D extruded prism layer compatible with the GMS interface and the Waterways Experimental Station's 3DFEMFAT finite element code for flow and contaminant transport in saturated and unsaturated soils. A uniform equilateral triangular grid overlays the physical domain. Increased resolution can be specified in areas of interest or in areas undergoing large geometrical change such as occurs during solidification. All elements exterior to the physical domain are eliminated. The elements closest to physical boundaries are adjusted to conform to the physical shape, and a smoothing operator is employed to assimilate these adjustments. Interior boundaries of multiple component systems are retained. This mesh generation strategy virtually eliminates user interaction which reduces the actual time required for solution substantially. The adaptive finite element mesh generator was applied to an illustrative subsurface soil situation. Therein, the multiple levels of resolution are presented as well as the various output formats.
