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.

Water is an important element for life on the earth. It is an essential natural resource for environmental sustenance. In India, water quality modeling studies are carried out from fresh water to marine water ecosystems. Some of the examples are Tehri reservoir, Chilka lake, Oatcake at Kashmir, Kodaikanal lake, Ooty lake at Tamil Nadu, rivers like Ganges, Narmada, Kaveri, and coastal regions like Hoogly estuary, Paradip, Vishakhapatnam, Kakinada, Chennai, Mangalore coast, Konkan coast and Gujarat coast. Water quality modeling plays a vital role in water quality studies. Numerical models are to be successfully calibrated and properly applied and it is to be improved our understanding of the complex interactions among different parameters such as temperature, biological oxygen demand, dissolved oxygen, salinity, and eutrophication in the fresh water and sea water environment.

Akademikern mit hydrogeologischer oder chemischer Grundausbildung sowie Studenten höherer Semester in den relevanten Fachgebieten erlaubt das Buch, anhand der beschriebenen Beispiele und Lösungen, eine eigenständige Erarbeitung der Sachverhalte. Die beiliegende CD-ROM ermöglicht zudem eine rasche Überprüfung der Ergebnisse, bzw. das Nachvollziehen aller Aufgaben und Lösungen anhand der beigefügten PhreeC-Eingabedateien. Da das Programm PhreeC kostenfrei verfügbar ist und mit Windows-Oberfläche auf der CD-ROM vorhanden ist, kann sofort mit der Modellierung begonnen werden.

Eco-hydraulic Modelling of Eutrophication for Reservoir Management

This study presents an systematic approach to water quality assessment, hybrid modelling and decision support for eutrophication management in deep reservoirs. It is found that during the summer monsoon the catchment runoff into the Yongdam reservoir induces a transfer of pollutants from a middle stratified layer to the surface layer. Although the transport mechanism limits nutrient accumulation on the bottom of the reservoir, it also offers an opportunity for on-going algae production in the surface water. Physically based modelling is used to understand the process of micro-scale turbulent mixing and its impact on the nutrient uptake by algae. Further, a data-driven model using clustering and partial least squares regression which uses results from a physically based model of the reservoir successfully predicts Chlorophyll-a concentrations.

This fascinating work is divided into two main sections. Part I reviews the basic principles of water movement in channels and the mass balance approach common to most models. It also covers the practical usefulness, model peer review, and guidance on model selection and calibration. Part II discusses flow simulation and prediction of time of travel, dye tracing and mixing, heat balance and temperature modeling, and reaeration and volatilization. This interesting, easy-to-read volume includes comprehensive reviews for the use of fluorescent water tracing dyes, longitudinal dispersion, evaporation and wind speed functions, prediction of saturation concentrations of dissolved oxygen, and reaeration coefficients. This book furnishes the reader with appendices which provide a synopsis of available computer models and gives a comprehensive listing of methods used to measure flow rates in rivers, tributaries, and pipes and channels introducing wastewaters into streams. This volume is a valuable, indispensable reference for all researchers, instructors, students in advanced environmental modeling courses, and practicing engineers.

The St. Johns River is the longest river in Florida, containing extensive freshwater wetlands, numerous large lakes, a wide estuarine channel, and a correspondingly diverse array of native flora and fauna. Water resource management in the river's watershed is the responsibility of the St. Johns River Water Management District (the District). The District must provide water for the region's 4.4 million residents as well as numerous industrial and agricultural users, all while protecting natural systems within the river basin. With population growth in the watershed expected to surpass 7.2 million in 2030, the District, through its water resources planning process, has begun to identify alternative sources of water beyond its traditional groundwater sources, including the potential withdrawal of 262 million gallons per day from the St. Johns River. To more comprehensively evaluate the environmental impacts of withdrawing this water from the river, the District embarked on a two-year Water Supply Impact Study (WSIS), and requested the involvement of the National Research Council. The present volume reviews the Phase I work of the WSIS and provides recommendations for improving Phase II.

2 nung der durch Änderungen in der Belastung und in den Entwässe rungsbedingungen verursachten Wirkungen meist nur sehr gering sind. Diese Feststellung gilt im besonderen Maße für alle jene Auf gaben, die sich mit der Wirkung des strömenden Wasser befassen, weil hier untergeordnete Abweichungen in der Schichtung, die durch Probebohrungen nicht aufgeschlossen werden, von großem Einfluß sein können. Aus diesem Grunde unterscheidet sich die Anwendung der theoretischen Bodenmechanik auf den Erd- und Grundbau ganz wesentlich von der Anwendung der technischen Mechanik auf den Stahl-, Holz- und Massivbau. Die elastischen Größen der Baustoffe Stahl oder Stahlbeton sind nur wenig veränderlich, und die Gesetze der angewandten Mechanik können für die praktische Anwendung ohne Einschränkung übertragen werden. Demgegenüber stellen die theoretischen Untersuchungen in der Bodenmechanik nur Arbeits hypothesen dar, weil unsere Kenntnisse über die mittleren physikalischen Eigenschaften des Untergrundes und über den Verlauf der einzelnen Schichtgrenzen stets unvollkommen und sogar oft äußerst unzuläng lich sind. Vom praktischen Standpunkt aus gesehen, sind die in der Bodenmechanik entwickelten Arbeitshypothesen jedoch ebenso an wendbar wie die theoretische Festigkeitslehre auf andere Zweige des Bauingenieurwesens. Wenn der Ingenieur sich der in den grundlegen den Annahmen enthaltenen Unsicherheiten bewußt ist, dann ist er auch imstande, die Art und die Bedeutung der Unterschiede zu er kennen, die zwischen der Wirklichkeit und seiner Vorstellung über die Bodenverhältnisse bestehen.
