Book Description
Hydrodynamics and Transport for Water Quality Modeling presents a complete overview of current methods used to describe or predict transport in aquatic systems, with special emphasis on water quality modeling. The book features detailed descriptions of each method, supported by sample applications and case studies drawn from the authors' years of experience in the field. Each chapter examines a variety of modeling approaches, from simple to complex. This unique text/reference offers a wealth of information previously unavailable from a single source. The book begins with an overview of basic principles, and an introduction to the measurement and analysis of flow. The following section focuses on rivers and streams, including model complexity and data requirements, methods for estimating mixing, hydrologic routing methods, and unsteady flow modeling. The third section considers lakes and reservoirs, and discusses stratification and temperature modeling, mixing methods, reservoir routing and water balances, and dynamic modeling using one-, two-, and three-dimensional models. The book concludes with a section on estuaries, containing topics such as origins and classification, tides, mixing methods, tidally averaged estuary models, and dynamic modeling. Over 250 figures support the text. This is a valuable guide for students and practicing modelers who do not have extensive backgrounds in fluid dynamics.

Book Description
The extent of harmful effects of pollution on atmospheric, terrestrial and aquatic environments can be translated into extreme temperature changes, dirty air, clean water shortages, and increased incidence of toxicity that harms every life on earth. Within a lifetime, our environment is changing drastically. Much of the information of environmental pollution impacts needs to be studied, from the mechanism of toxic nanoparticles on the molecular level to the detection of trace gases on the satellite perspective. It is therefore essential to develop advanced monitoring techniques, e- cient process technologies and health impact assessment tools to ?ll the gaps in our scienti?c knowledge. This edition of “Atmospheric and Biological Environmental Monitoring” is a handful of recent developments and techniques from environmental scientists in well-diversi?ed ?elds. These collections of manuscripts are extracts from the recently concluded “7th International Symposium on Advanced Environmental Monitoring” organized by the ADvanced Environmental Monitoring and Research Center (ADEMRC), Gwangju Institute of Science and Technology (GIST), Korea and held on February 25–28, 2008 in Honolulu, Hawaii. The three parts highlight important aspects of emerging environmental monitoring technologies: Atmospheric Environment, Contaminants Control Process, and Environmental Toxicity Asse- ment. Observational tools presented in the ?rst part ranges from in-situ measurements to satellite remote sensing for atmospheric monitoring. Highlighted in the second part is the recently developed water quality monitoring system for lake strati?cation and membrane technologies for detection and removal of contaminants. Lastly, toxicity monitoring of endocrine disruptors and nanoparticles are highlighted in the third part with new discoveries.

Book Description
This Scientific and Technical Report (STR) presents the findings of the IWA Task Group on River Water Quality Modelling (RWQM). The task group was formed to create a scientific and technical base from which to formulate standardized, consistent river water quality models and guidelines for their implementation. This STR presents the first outcome in this effort: River Water Quality Model No. 1 (RWQM1). As background to the development of River Water Quality Model No.1, the Task Group completed a critical evaluation of the current state of the practice in water quality modelling. A major limitation in model formulation is the continued reliance on BOD as the primary state variable, despite the fact BOD does not include all biodegradable matter. A related difficulty is the poor representation of benthic flux terms. As a result of these limitations, it is impossible to close mass balances completely in most existing models. These various limitations in current river water quality models impair their predictive ability in situations of marked changes in a river's pollutant load, streamflow, morphometry, or other basic characteristics. RWQM 1 is intended to serve as a framework for river water quality models that overcome these deficiencies in traditional water quality models and most particularly the failure to close mass balances between the water column and sediment. To these ends, the model incorporates fundamental water quality components and processes to characterise carbon, oxygen, nitrogen, and phosphorus (C, O, N, and P) cycling instead of biochemical oxygen demand as used in traditional models. The model is presented in terms of process and components represented via a 'Petersen stoichiometry matrix', the same approach used for the IWA Activated Sludge Models. The full RWQM1 includes 24 components and 30 processes. The report provides detailed examples on reducing the numbers of components and processes to fit specific water quality problems. Thus, the model provides a framework for both complicated and simplified models. Detailed explanations of the model components, process equations, stoichiometric parameters, and kinetic parameters are provided, as are example parameter values and two case studies. The STR is intended to launch a participatory process of model development, application, and refinement. RWQM1 provides a framework for this process, but the goal of the Task Group is to involve water quality professionals worldwide in the continued work developing a new water quality modelling approach. This text will be an invaluable reference for researchers and graduate students specializing in water resources, hydrology, water quality, or environmental modelling in departments of environmental engineering, natural resources, civil engineering, chemical engineering, environmental sciences, and ecology. Water resources engineers, water quality engineers and technical specialists in environmental consultancy, government agencies or regulated industries will also value this critical assessment of the state of practice in water quality modelling. Key Features presents a unique new technical approach to river water quality modelling provides a detailed technical presentation of the RWQM1 water quality process model gives an informative critical evaluation of the state of the practice in water quality modelling, and problems with those practices provides a step by step procedure to develop a water quality model Scientific & Technical Report No. 12
