This book provides essential information on the higher mathematical level of approximation over the gradually varied flow theory, also referred to as the Boussinesq-type theory. In this context, it presents higher order flow equations, together with their applications in a broad range of pertinent engineering and environmental problems, including open channel, groundwater, and granular material flows.

Triggerd primarily byill effects of polluted air, soil and water resources on living species, public concern for environmental quality has been growing during the past four decades or so. One manifestation of this concern is found in occurrence of public debates as well as in the demand for full environmental impact assessment before a water-resources project is approved. Engineering soundness and economic feasibility are no longer sufficient criteria for construction of hydraulic works. As a result, environmental considerations have become very much a part of hydraulic analyses. In response to growing environmental concerns, the field of hydraulics has expanded and a new branch, called Environmental Hydraulics, has emerged. The focus of this branch is on hydraulic analyses of those environmental issues that are important for protection, restoration, and managementof environmental quality. The motivation for this book grew out of the desire to provide a hydraulic discussion of some of the key environmental issues.It is hoped that the book would serve to stimulate others to write more comprehensive texts on this subject of growing importance.

Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.

This book presents the theory and computation of open channel flows, using detailed analytical, numerical and experimental results. The fundamental equations of open channel flows are derived by means of a rigorous vertical integration of the RANS equations for turbulent flow. In turn, the hydrostatic pressure hypothesis, which forms the core of many shallow water hydraulic models, is scrutinized by analyzing its underlying assumptions. The book's main focus is on one-dimensional models, including detailed treatments of unsteady and steady flows. The use of modern shock capturing finite difference and finite volume methods is described in detail, and the quality of solutions is carefully assessed on the basis of analytical and experimental results. The book's unique features include: * Rigorous derivation of the hydrostatic-based shallow water hydraulic models * Detailed treatment of steady open channel flows, including the computation of transcritical flow profiles * General analysis of gate maneuvers as the solution of a Riemann problem * Presents modern shock capturing finite volume methods for the computation of unsteady free surface flows * Introduces readers to movable bed and sediment transport in shallow water models* Includes numerical solutions of shallow water hydraulic models for non-hydrostatic steady and unsteady free surface flows This book is suitable for both undergraduate and graduate level students, given that the theory and numerical methods are progressively introduced starting with the basics. As supporting material, a collection of source codes written in Visual Basic and inserted as macros in Microsoft Excel (R) is available. The theory is implemented step-by-step in the codes, and the resulting programs are used throughout the book to produce the respective solutions.

Stilling basins utili z ing a hydraulic jump for energy dissipation are w i d e l y used in hydraulic engineering . D a Vinci was the first to describe the hydraulic jump, and Bidone conducted classical experiments about 170 years ago . Stilling basins w e r e developed in the thirties with signif- cant design improvements being made during the last sixty years . Although w e l l - a c c e p t e d guidelines for a successful design are presently available, the information for the design of such dissipators is not yet compiled in book form . This book provides state-of-the-art information on hydraulic jumps and associat ed stilling basins . A large numbe r of papers on the to pics are reviewed. T h e present trends of the art of designing a stilli ng basin are discussed and ideas for future research are outlined. Design criteria and recommendat ions are frequently given . However, this should not be considered as a r eady-to -use guideline since the design of an effective stilling basin is much more comple x than following general design steps . The book is divided into two parts. Part 1 on hydraulic jumps is c- prised of chapters 2 to 5. Part 2 consisting of chapters 6 to 14 deals with various hydraulic structures used to dissipate energy. The lists of notation and references are provided in each part separately although the same notation is u sed throughout.

The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

This book provides 1-page short biographies of scientists and engineers having worked in the areas of hydraulic engineering and fluid dynamics in the USA. On each page, a notable individual is highlighted by: (1) Exact dates and locations of birth and death; (2) Educational and professional details, including also awards received; (3) Reasons for inclusion in the book by highlighting key publications; (4) Short bibliography including both individual's own, and source literature such as Who's Who details, or origination details of the portrait; (5) In most cases, an illustrative portrait or photo showing, for example, a book cover of the individual, or photograph of a typical work such as a dam or a canal. This volume includes almost 1,000 individuals, of which there are only 2 women. The book also provides a detailed Index, and a 2-page list of individuals (normally born in Europe) listed in previous volumes (1 and 2), but having a relation to this volume 3. The book also contains a map of the USA highlighting the major American rivers, with a close relation to projects carried out by several of the individuals presented in the book. This book provides a beautiful overview of the many scientists and engineers having contributed to the current knowledge in hydraulic engineering and fluid mechanics. The author made every effort in compiling the most important hydraulicians of the USA in this work as it will become much more difficult in future decades to find biographical details on these, given the current policy that so few memoirs or necrologues are published.

Il libro presenta un aggiornamento delle conoscenze tecnico-scientifiche nel settore, che purtroppo non trovano adeguati riferimenti nella bibliografia italiana attualmente disponibile. La attivita di ricerca scientifica degli Autori ha significativamente contribuito all avanzamento dello stato dell arte sull idraulica dei sistemi fognari nel corso dell ultimo decennio. I risultati della ricerca, oltre ad essere stati pubblicati su prestigiose riviste internazionali, sono stati inseriti nelle Linee Guida per la progettazione adottate dall Ente Normatore Tedesco per i Sistemi Fognari e le Acque Reflue (A.T.V.) e sono in vie di recepimento nelle Direttive della Comunita Europea per la progettazione dei sistemi fognari. Il libro e rivolto a studenti dei corsi di studio nel settore dell ingegneria Civile ed Ambientale. Particolare interesse e rivolto verso i professionisti operanti nel settore della ingegneria idraulica e della pianificazione urbana, per i quali e forte l esigenza di testi che contengano indicazioni di carattere sia teorico che pratico, finalizzate alla progettazione di sistemi di drenaggio nei centri abitati. Il testo intende colmare le importanti lacune che ancora caratterizzano la letteratura italiana nel settore e che spesso sono alla base di errori progettuali, con ovvie conseguenze sulla sicurezza dei centri abitati (come testimoniato dai frequenti fenomeni di allagamento che sono stati registrati negli ultimi anni).

1m urspriinglichen Entwurf dieses Handbuchs vor zwei Jahrzehnten hatten wir geplant, dem Band II "Die Zelle" in Band III die allgemeine Pathologie der "Zwischensubstanzen, Gewebe und Organe" folgen zu lassen. Aus vielfachen Er- fahrungen ist diese strenge Zasur zwischen den Zellen und den Zwischensubstanzen heute nicht mehr aufrecht zu halten. Das gilt besonders yom Nervensystem in seinen normalen und krankhaft veranderlen Strukturen. So sind wir HERMANN HAGER besonders dankbar, daB er im ersten Beitrag dieses Bandes: "Allgemeine morphologische Pathologie des Nervensystems" von der unauflosbaren Einheit der cellularen und zwischenzelligen Strukturen des Nervensystems in Orlhologie und Pathologie ausgegangen ist. Erstmals wieder seit SPIELMEYERS "Histopathologie des Nervensystems" von 1922 werden hier die Strukturelemente des Nervensystems unter den Prinzipien der allgemeinen Patho- logie dargestellt, diesmal vor allem auch die Veranderungen der Feinstrukturen im elektronenmikroskopischen Bild. Unter dem Leitmotiv "Organstruktur als Grundlage der Organleistung und Organerkrankung" schlieBt sich der Beitrag von HUGO NOETZEL tiber "Das zentrale und periphere N ervensystem" an; er veranschaulicht die Bedeutung des Bauplans des Nervensystems fUr seine Pathologie an einer Reihe typischer Er- krankungen. Die Vereinigung dieser beiden Beitrage im gleichen Bandteil rechtferligt sich nicht zuletzt durch das allgemeine groBe theoretische und praktische Interesse fUr die morphologische Pathologie des Nervensystems in unseren Tagen. Moge der Band unter den Gesichtspunkten der allgemeinen Pathologie zu einem vertiefteren Verstandnis dieses Systems und seiner Orthologie und Patho- logie beitragen.
