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.

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.

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.

This book was released on 1988 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although not problematic within this reservoir, unacceptably low dissolved oxygen concentrations farther downstream in the system of reservoirs in the Cumberland River Basin have caused concern. This model study was undertaken to evaluate the water quality (specifically temperature and dissolved oxygen) impacts of operational changes at individual reservoir outlet structures. The study was also designed to reveal the interactions between hydrodynamics and stratification within the reservoir. Unstable stratification is thought to be responsible for additional problems in the reservoir: absence of an anticipated substantial fishery and a less than desirable amount of contact recreation. The concept of installing submerged weirs at the mouths of two of the reservoir's embayments within an established recreational site was proposed to help alleviate these 2 problems. As Cordell Hull Lock and Dam operates as a run-of-the-river navigation project on the main-stem Cumberland River, no significant operational changes at this site are possible. The reservoir is characterized by high flows, intermittent moderate to weak thermal stratification, and a relatively shallow pool. These factors combine, as was demonstrated by the model testing results, to preclude significant control over the release quality characteristics. However, the advective nature of the reservoir presents an advantage. Any changes to the quality of incoming water of Cordell Hull Reservoir will be propagated downstream, largely intact. (EDC).

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The Everglades region known as the Southern Inland and Coastal Systems is an important area that supports numerous endangered species and plays a crucial role in regulating water-quality conditions in Florida Bay. Taylor Slough is a major feature of this region and represents the primary surface-water pathway for freshwater inputs to Florida Bay. The slough is also subject to intensive flow management under the Comprehensive Everglades Restoration Plan, yet the consequences of such management for water-quality in these oligotrophic and sensitive wetlands are not well understood. A flexible phosphorus water-quality model was therefore developed and tested as an exploratory management tool for the region. Complex local hydrodynamics required that a spatially-distributed hydrodynamic model be used to simulate flow and transport and the USGS model FTLOADDS was selected for this. A user-definable biogeochemical reactive component (aRSE) was then coupled with the hydrodynamic model and the resulting FTaRSELOADDS model was tested against analytical solutions and field data.
Download or read book Water Environment Modeling written by Clark C.K. Liu and published by CRC Press. This book was released on 2021-11-01 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Environment Modeling covers the formulations and applications of mathematical models that simulate water flow and chemical transport in rivers, lakes, groundwater, estuaries, coastal, and ocean waters. These models are used to evaluate the response of water environment to human interventions and serve as useful analytical tools for water pollution control and resource management. Simple and comprehensive modeling techniques and their practical applications are presented with examples and exercises, most of which are derived from actual case studies. In general, simple models can be solved analytically and comprehensive models require numerical solutions. While simple models are usually adopted for preliminary assessment of a particular water environment, comprehensive models are used to provide detailed spatial and temporal variations of pollutants in complex environments. The system-based models in the forms of integral equations are introduced as an alternative modeling approach. This textbook is ideal for advanced undergraduate students and graduate students in civil and environmental engineering and related academic fields. It is also suitable as a reference book for practicing engineers and scientists. Authors: Clark C.K. Liu is Emeritus Professor of the Department of Civil and Environmental Engineering at University of Hawaii and former Environmental Engineering Director of US National Science Foundation. Pengzhi Lin is Professor of State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan University. He is the author of Numerical Modeling of Water Waves (CRC Press, 2008).

Download or read book Water Quality Modeling That Works written by Wu-Seng Lung and published by Springer Nature. This book was released on 2022-01-17 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical guidance for environmental engineers and scientists charged with assessing the cause-and-effect of pollutants in receiving water systems. Instead of blindly running models, which is a practice seen too often in today’s field that can result in results with uncertainty, modelers must first understand the physical insights of the specific water systems in order to properly calibrate the parameters of the models. This book reinforces the critical importance of properly understanding the physical attributes of water systems by drawing on the author’s extensive experience in modeling with strong data support. This is also what sets this book apart from the volumes currently available in the water quality modeling field – nearly all other books in the field are categorized as textbooks, and unlike this book, offer few practical examples or exercises to follow. Environmental engineers and scientists engaged in quantifying the water quality impacts of pollutants to specific water systems will find this book valuable in their day-to-day practices. This book is a necessary volume for water quality engineers and scientists to consult for the regulatory planning and management of water systems
