Computational Hydraulics introduces the concept of modeling and the contribution of numerical methods and numerical analysis to modeling. It provides a concise and comprehensive description of the basic hydraulic principles, and the problems addressed by these principles in the aquatic environment. Flow equations, analytical and numerical solutions are included. The necessary steps for building and applying numerical methods in hydraulics comprise the core of the book and this is followed by two different example applications of computational hydraulics: river systems and water quality modelling of lakes and rivers. The theory and exercises included in the book promote learning of concepts within academic environments. Computational Hydraulics is intended for under-graduate and graduate students, researchers, members of governmental and non-governmental agencies and professionals involved in management of the water related problems.

Illustrates theories and associated mathematical expressions with numerical examples using various methods, leading to exact solutions, more accurate results, and more computationally efficient techniques
This book presents the derivations of the equations of motion for all structure foundations using either the continuous model or the discrete model. This mathematical display is a strong feature of the book as it helps to explain in full detail how calculations are reached and interpreted. In addition to the simple 'uniform' and 'straight' beams, the book introduces solution techniques for the complicated ‘non uniform’ beams (including linear or non-linear tapered beams), and curved beams. Most of the beams are analyzed by taking account of the effects of shear deformation and rotary inertia of the beams themselves as well as the eccentricities and mass moments of inertia of the attachments.
Demonstrates approaches which dramatically cut CPU times to a fraction of conventional FEM
Presents "mode shapes" in addition to natural frequencies, which are critical for designers
Gives detailed derivations for continuous and discrete model equations of motions
Summarizes the analytical and numerical methods for the natural frequencies, mode shapes, and time histories of
straight structures
rods
shafts
Euler beams
strings
Timoshenko beams
membranes/thin plates
Conical rods and shafts
Tapered beams
Curved beams
Has applications for students taking courses including vibration mechanics, dynamics of structures, and finite element analyses of structures, the transfer matrix method, and Jacobi method
This book is ideal for graduate students in mechanical, civil, marine, aeronautical engineering courses as well as advanced undergraduates with a background in General Physics, Calculus, and Mechanics of Material. The book is also a handy reference for researchers and professional engineers.

Author(s)/Editor(s): Béla Bodó, Colin Jones | Size: 30 MB | Format:PDF | Quality:Original preprint | Publisher: Wiley-Blackwell | Year: 2013 | pages: 608 | ISBN: 0470659432 / 978-0070407695
Introduction to Soil Mechanics covers the basic principles of soil mechanics, illustrating why the properties of soil are important, the techniques used to understand and characterise soil behaviour and how that knowledge is then applied in construction. The authors have endeavoured to define and discuss the principles and concepts concisely, providing clear, detailed explanations, and a well–illustrated text with diagrams, charts, graphs and tables. With many practical, worked examples and end–of–chapter and coverage of Eurocode 7, Introduction to Soil Mechanics will be an ideal starting point for the study of soil mechanics and geotechnical engineering.

A comprehensive treatment of open channel flow, Open Channel Flow: Numerical Methods and Computer Applications starts with basic principles and gradually advances to complete problems involving systems of channels with branches, controls, and outflows/ inflows that require the simultaneous solutions of systems of nonlinear algebraic equations coupled with differential equations. The book includes a CD that contains a program that solves all types of simple open channel flow problems, the source programs described in the text, the executable elements of these programs, the TK-Solver and MathCad programs, and the equivalent MATLAB® scripts and functions.
The book provides applied numerical methods in an appendix and also incorporates them as an integral component of the methodology in setting up and solving the governing equations. Packed with examples, the book includes problems at the end of each chapter that give readers experience in applying the principles and often expand upon the methodologies use in the text. The author uses Fortran as the software to supply the computer instruction but covers math software packages such as MathCad, TK-Solver, MATLAB, and spreadsheets so that readers can use the instruments with which they are the most familiar. He emphasizes the basic principles of conservation of mass, energy, and momentum, helping readers achieve true mastery of this important subject, rather than just learn routine techniques.
With the enhanced understanding of the fundamental principles of fluid mechanics provided by this book, readers can then apply these principles to the solution of complex real-world problems. The book supplies the knowledge tools necessary to analyze and design economical and properly performing conveyance systems. Thus not only is the book useful for graduate students, but it also provides professional engineers the expertise and knowledge to design well performing and economical channel systems.

Geotechnique Symposium in Print 2011: The theme of this symposium blends together two areas of research which relate to the effects of suction and partial saturation on soil behaviour and the study of compaction as a method of soil improvement. The recurring interest in these areas of research, together with the recent increase in the number of international conferences dedicated to unsaturated soils, is a clear indication of the continued relevance of this theme to the geotechnical profession.

Guidance on Protecting and Extending the Life of Suspension Bridges
Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also an essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present-day span lengths close to two kilometers.
Many of these bridges carry significant traffic and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend a considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life.
Captures the Experience of More Than 20 Suspension Bridge Operators
Inspection, Evaluation and Maintenance of Suspension Bridges is written by the bridge owners and practitioners who strive to cost-effectively manage these bridges. It is invaluable to everyone interested not only in suspension bridges but in the upkeep of any bridges―students, designers, maintenance personnel, contractors, and owners.
Describes the evolution and trends in the operation and maintenance of cable supported bridges
Contains the latest methods for evaluating cable supported bridge capacities and durability
Presents suspension bridge security risk management aspects and Bayesian network-based methodology for risk evaluation
This volume discusses state-of-the-art practice in suspension bridge inspection, evaluation, and rehabilitation methods used worldwide, described by the personnel directly involved with managing them. Its companion volume presents detailed case studies of specific bridges to give a comprehensive picture of how suspension bridges are maintained around the world.
