Increases in computer power have now enabled engineers to combine materials science with structural mechanics in the design and the assessment of concrete structures. The techniques developed have become especially useful for the performance assessment of such structures under coupled mechanistic and environmental actions. This allows effective management of infrastructure over a much longer life cycle, thus satisfying the requirements for durability and sustainability. This ground-breaking new book draws on the fields of materials and structural mechanics in an integrated way to address the questions of management and maintenance. It proposes a realistic way of simulating both constituent materials and structural responses under external loading and under ambient conditions. Where the research literature discusses component or element technology related to performance assessment, this book uniquely covers the subject at the level of the whole system including soil foundation, showing engineers how to model changes in concrete structures over time and how to use this for decision making in infrastructure maintenance and asset management.

Bridge scour is the loss of soil by erosion due to flowing water around bridge supports. Bridge scour includes general scour and local scour. General scour is the aggradation or degradation of the riverbed not related to the presence of local obstacles. Aggradation is the gradual and general accumulation of sediments on the river bottom; one possible scenario is the existence of slope failures upstream leading to the formation of spoils in the river, the erosion of these spoils under higher velocities, followed by transport and deposition under lower velocities at the aggrading location. Degradation is the gradual and general removal of sediments from the riverbed; one possible scenario is the man-made straightening of a river course, a resulting increase in the water velocity and the associated increase in erosion. Local scour is the scour around obstacles to the water flow; it includes pier scour, abutment scour, and contraction scour. Pier scour is the removal of the soil around the foundation of the pier; abutment scour is the removal of the soil around the abutment at the junction between the bridge and the embankment; contraction scour is the removal of the soil from the bottom of the river due to narrowing of the river channel created by the approach embankments for the bridge.

Computer-based transportation applications and databases have been a fact of life for several decades. Transportation information, however, has often not been accessible in a user-friendly manner, and integrating data from diverse sources has too often been a challenge in itself. Geographic Information Systems (GIS) have revolutionized spatial planning and decision making by using the spatial dimension of the depicted world as a common thread according to which all information can be referenced. The application of GIS to transportation research (GIS-T) is quickly becoming a mature domain of application of the GIS technology and has gained full recognition among transportation practitioners and academics.
This book fills a void by providing an overview of the state-of-the-art of GIS for transportation, from data management issues, to data manipulation and analysis, including considerations brought to the forefront by real-time and mobile computing. The twenty-two original contributions by internationally acclaimed authors will be a key reference for practitioners, students and scholars.

Through previous editions, Peter O'Neil has made rigorous engineering mathematics topics accessible to thousands of students by emphasizing visuals, numerous examples, and interesting mathematical models. Now, ADVANCED ENGINEERING MATHEMATICS features revised examples and problems as well as newly added content that has been fine-tuned throughout to improve the clear flow of ideas. The computer plays a more prominent role than ever in generating computer graphics used to display concepts and problem sets. In this new edition, computational assistance in the form of a self contained Maple Primer has been included to encourage students to make use of such computational tools. The content has been reorganized into six parts and covers a wide spectrum of topics including Ordinary Differential Equations, Vectors and Linear Algebra, Systems of Differential Equations and Qualitative Methods, Vector Analysis, Fourier Analysis, Orthogonal Expansions, and Wavelets, and much more.

Stepped channel design has been in use for more than 3,500 years. Recent advances in technology have triggered a regained interest in stepped design, although much expertise has been lost in the last 80 years. The steps significantly increase the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are also used in water treatment plants to enhance the air-water transfer of atmospheric gases (e.g. oxygen, nitrogen) and of volatile organic components (VOC). Results from more than forty-five laboratory studies and four prototype investigations were re-analysed and compared. The book provides a new understanding of stepped channel hydraulics, and is aimed both at researchers and professionals.

FOCUSING ON CONTAMINANT FATE AND TRANSPORT, DESIGN OF ENVIRONMENTAL-CONTROL SYSTEMS, AND REGULATORY CONSTRAINTS
This textbook details the fundamental equations that describe the fate and transport of contaminantsin the water environment. The application of these fundamental equations to the design of environmental-control systems and methodologies for assessing the impact of contaminant discharges into rivers, lakes, wetlands, ground water, and oceans are all covered. Readers learn to assess how much waste can be safely assimilatedinto a water body by developing a solid understanding of the relationship between the type of pollutant discharged, the characteristics of the receiving water, and physical, chemical, and biological impacts. In cases of surface runoff from urban and agricultural watersheds, quantitative relationships between the quality of surface runoff and the characteristics of contaminant sources located within the watersheds are presented.
