This book concerns the practical solution of Partial Differential Equations (PDEs). It reflects an interdisciplinary approach to problems occurring in natural environmental media: the hydrosphere, atmosphere, cryosphere, lithosphere, biosphere and ionosphere. It assumes the reader has gained some intuitive knowledge of PDE solution properties and now wants to solve some for real, in the context of practical problems arising in real situations. The practical aspect of this book is the infused focus on computation. It presents two major discretization methods a " Finite Difference and Finite Element. The blend of theory, analysis, and implementation practicality supports solving and understanding complicated problems. It is divided into three parts. Part I is an overview of Finite Difference Methods. Part II focuses on Finite Element Methods, including an FEM tutorial. Part III deals with Inverse Methods, introducing formal approaches to practical problems which are ill-posed.

For readers with some competence in PDE solution properties, this book offers an interdisciplinary approach to problems occurring in natural environmental media: the hydrosphere, atmosphere, cryosphere, lithosphere, biosphere and ionosphere. It presents two major discretization methods: Finite Difference and Finite Element, plus a section on practical approaches to ill-posed problems. The blend of theory, analysis, and implementation practicality supports solving and understanding complicated problems.

The coastal ocean comprises the semi-enclosed seas on the continental shelf, including estuaries and extending to the shelf break. This region is the focus of many serious concerns, including coastal inundation by tides, storm surges, or sea level change; fisheries and aquaculture management; water quality; harmful algal blooms; planning of facilities (e.g., power stations); port development and maintenance; and oil spills. This book addresses modeling and simulation of the transport, evolution, and fate of particles (physical and biological) in the coastal ocean. It is the first to summarize the state of the art in this field and direct it toward diverse applications, for example in measuring and monitoring sediment motion, oil spills, and larval ecology. This is an invaluable textbook and reference work for advanced students and researchers in oceanography, geophysical fluid dynamics, marine and civil engineering, computational science, and environmental science.

Sustainable management of the natural resources that support human life and flourishing, once simply a desirable goal, is now an imperative outcome. Not only the problems we face dwindling fisheries, shrinking water supplies but even the proposed solutions conversion of biomass to fuels demand a sustainable framework within which to operate. This book introduces such a framework to those students in science and engineering who will manage natural resources professionally whether through conservation, conversion or harvesting. It is an indispensable resource for courses in a broad range of disciplines that wish to incorporate a sustainable perspective: ecology, natural resource and wildlife management, agriculture, forestry, geography, environmental engineering, and environmental economics. The book is a valuable toolkit for graduate students in professional programs in environmental science and natural resource management. The text assumes undergraduate mathematics through ordinary differential equations and some basic concepts of optimization including linear programming. Features Key Concepts of Sustainability Presented in an Analytical Framework Topics include: harvest, sustainability, effort, extraction, extinction, consumptive use, riparian rights, etc. Problem Sets that Apply Quantitative Tools Found at the end of each chapter, these extensive problem sets give students an opportunity to apply the tools they have learned in a variety of natural resource management contexts. Matlab and Excel Programs Integrated into the Text Available for download on the book s website, these programs enhance understanding and provide further tools for research and professional use. Supports ASCE Body of Knowledge for the 21st Century recommendations: the 21stCentury Civil Engineer must demonstrate: an ability to evaluate the sustainability of engineered systems and services, and of the natural resource base on which they depend; and to design accordingly.
