Computational Modelling in Hydraulic and Coastal Engineering

Combines More Than 40 Years of Expert Experience Computational modelling and simulation methods have a wide range of applications in hydraulic and coastal engineering. Computational Modelling in Hydraulic and Coastal Engineering provides an introductory but comprehensive coverage of these methods. It emphasizes the use of the finite differences method with applications in reservoir management, closed-conduit hydraulics, free-surface channel and coastal domain flows, surface gravity waves, groundwater movement, and pollutant and sediment transport processes. It focuses on applications rather than lengthy theories or derivations of complex formulas and is supported by a wealth of hands-on numerical examples and computer codes written in MATLAB but available also in BASIC. PowerPoint presentations and learning assignment projects/quizzes, along with learning assessment rubrics, are included. A comprehensive study highlighting the infinite differences method, this book: Covers the fundamentals of flow in pressurized conduits Contains solutions for the classical Hardy Cross pipe network problem Designates the mathematical description of groundwater flow in confined and unconfined aquifers Provides numerical examples for one- and two-dimensional applications including saltwater intrusion Presents examples of transport of pollutants, sediment and air bubbles using Eulerian and Lagrangian solution methodologies Includes information on weighted residuals, the finite elements method, and the boundary integral method Computational Modelling in Hydraulic and Coastal Engineering suits senior-level undergraduates and graduate students as well as practitioners such as coastal and maritime engineers, environmental engineers, civil engineers, computer modellers, and hydro-geologists.

Christopher Koutitas graduated from the Department of Civil Engineering at Aristotle University of Thessaloniki (AUTh) in 1970. He attended the graduate program in water resources and earned an MSE from the Department of Civil and Geological Engineering at Princeton University in 1971. He earned a doctorate from the Department of Civil Engineering at AUTh in 1976. His main research activity area is computational modelling in coastal and harbor engineering, aiming at the technically and environmentally optimal design of coastal structures. Dr. Koutitas has published more than 200 papers and two relevant books. He is now a professor emeritus of AUTh. Panagiotis D. Scarlatos earned his diploma degree (1972) and doctorate degree (1981) in civil engineering from the Aristotle University of Thessaloniki, Greece. In 1989 he joined Florida Atlantic University as a faculty member of the Ocean Engineering Department before moving to the Civil, Environmental and Geomatics Department. He is currently a professor in the same department and director of the Center for Intermodal Transportation Safety and Security. He has written more than 130 technical publications, and has served as an expert witness in a variety of national and international cases pertaining to water resources and related infrastructure.
