• A strong emphasis on the application of efficient solution techniques, computational procedures, and numerical methods suitable for computer analyses;

• Complete coverage of steady and unsteady flow techniques;

• A new chapter on sediment transport and updated chapters on uniform flow and two dimensional flow techniques;

• New and updated problem sets and exercises, a solutions manual for instructors, and a CD-ROM with short computer programs in FORTRAN that include the input data for sample problems and the associated computer output.

Open-Channel Flow, Second Edition is written for students in senior-level undergraduate and graduate courses on steady and unsteady open-channel flow and for civil engineers needing up-to-date and relevant information on the latest developments and techniques in the field.

Nominated by Tsinghua University as an outstanding Ph.D. thesis, this book investigates the mechanical properties of unsaturated compacted clayey soil, the multi-field coupling consolidation theory of unsaturated soil and its application to a 261.5 m high earth-rockfill dam. It proposes a multi-field coupling analysis method of consolidation, and develops an efficient and practical finite element (FE) program for large-scale complex earth-rockfill dams. The book is primarily intended for researchers studying the multi-field coupling analysis of seepage consolidation.

These proceedings of a NATO Advanced Research Workshop on "Environmental Reconstruction in Headwater Areas" provide a landmark in the evolution of a distinctive movement, perhaps an emerging new philosophy, within the practice of headwater management. The Headwater Control movement traces its history back to the First International Conference on Headwater Control, Prague, 1989. Throughout this brief history, Headwater Control has remained a typical environment movement 'ad hocracy'. At its meetings, for every convert to the multidisciplinary, integrative, practical, interventionist, and above-all 'green' ideals of the group, there have been several delegates who have found the whole concept both new and slightly incomprehensible. One reason for this has been the Headwater Control practice of trying to bring together scientists, practitioners, policy-makers and non-government environmentalist organisations. The group's larger meetings have always been federal gatherings. Sponsorship has been shared with invited participation from associations representing hydrological science, soil conservation, erosion control, forestry, environmental activism and so forth. These delegations may have included fellow travellers in the work to protect headwater environments, but their main concerns have not necessarily coincided with the Headwater Control group's prescriptions for the environmental regeneration of headwater regions. The Liberec Workshop, whose proceedings are distilled into this volume, provided a first opportunity for the scattered supporters of Headwater Control to talk among themselves and fmd out to what degree there really is a shared vision of the way forward in headwater management, restoration and protection.

This book is intended to be a text for undergraduate students of coastal engineering. It also serves as a reference for graduate students and practicing engineers, building on a basic foundation in coastal engineering. Finally, it is a guide for people in related disciplines. Coastal managers may use the book to cover the more theoretical and engineering-related aspects of their trade. Its subject matter is of interest to geographers, planners and coastal scientists alike.

Each year more than 200 million people are affected by floods, tropical storms, droughts, earthquakes, and also operational failures, wars, terrorism, vandalism, and accidents involving hazardous materials. These are part of the wide variety of events that cause death, injury, and significant economic losses for the countries affected.

In an environment where natural hazards are present, local actions are decisive in all stages of risk management: in the work of prevention and mitigation, in rehabilitation and reconstruction, and above all in emergency response and the provision of basic services to the affected population. Commitment to systematic vulnerability reduction is crucial to ensure the resilience of communities and populations to the impact of natural and manmade hazards.

Current challenges for the water and sanitation sector require an increase in sustainable access to water and sanitation services in residential areas, where natural hazards pose the greatest risk. In settlements located on unstable and risk-prone land there is growing environmental degradation coupled with extreme conditions of poverty that increase vulnerability. The development of local capacity and risk management play vital roles in obtaining sustainability of water and sanitation systems as well as for the communities themselves.

Unfortunately water may also represent a potential target for terrorist activity or war conflict and a deliberate contamination of water is a potential public health threat. An approach which considers the needs of communities and institutions is particularly important in urban areas affected by armed conflict. Risk management for large rehabilitation projects has to deal with major changes caused by conflict: damaged or destroyed infrastructure, increased population, corrupt or inefficient water utilities, and impoverished communities.

Water supply and sanitation are amongst the first considerations in disaster response. The greatest water-borne risk to health in most emergencies is the transmission of faecal pathogens, due to inadequate sanitation, hygiene and protection of water sources. However, some disasters, including those involving damage to chemical and nuclear industrial installations, or involving volcanic activity, may create acute problems from chemical or radiological water pollution. Sanitation includes safe excreta disposal, drainage of wastewater and rainwater, solid waste disposal and vector control.

This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Ohrid, Macedonia under the auspices of the NATO Security Through Science Programme and addressed problems Risk management of water supply and sanitation systems impaired by operational failures, natural disasters and war conflicts.

The main purpose of the workshop was to critically assess the existing knowledge on Risk management of water supply and sanitation systems, with respect to diverse conditions in participating countries, and promote close co-operation among scientists with different professional experience from different countries.

The ARW technical program comprised papers on 4 topics: (a) Vulnerability of Wastewater and Sanitation Systems, (b) Vulnerability of Drinking Water Systems, (c) Emergency response plans, and (d) Case studies from regions affected by Drinking Water System, Wastewater and Sanitation System failures.

The increasing risk of severe droughts and water shortages emphasizes the need for an integrated approach to drought mitigation. However, effective tools for the implementation of such an approach have not been available till now. This book contributes to an improved preparedness for drought in water supply systems, providing tools useful for a better decision making process in drought management. It presents methods and software features of a Decision Support System (DSS) developed within a European research project and consists of three main parts. The first part deals with the advanced techniques for hydrological drought identification and monitoring; the second analyses the successful use of climate-crop-soil models in defining deficit irrigation strategies; the third provides tools for improving the operation of irrigation supply reservoirs. All methods are embedded in a user-friendly DSS package that has been applied in several Case Studies of Mediterranean countries (Portugal, Italy, Tunisia, Jordan and Syria) and whose results are also compared.

A clear, up-to-date presentation of the principles of flow in open channels

A fundamental knowledge of flow in open channels is essential for the planning and design of systems to manage water resources. Open-Channel Flow conveys this knowledge through the use of practical problems that can be solved either analytically or by simple numerical methods that do not require the use of computer software.

This completely up-to-date text includes several features not found in any other book on the subject. It derives one- dimensional equations of motion using both a simplified approach and a rigorous approach, and it explains the distinction between the momentum and mechanical energy equations. The author places great emphasis on identifying the types and locations of the control sections that are essential in analyzing flow profiles, and he includes a section on recently recognized nonunique flow profiles.

Offering numerous worked examples that are helpful in understanding the basic principles and their practical applications, this book:

• Presents the latest computational methods for profiling spatially varied and unsteady flow
• Includes end-of-section exercises that measure and build understanding
• Fully explains governing equations in algebraic and differential form
• Brings sluice-gate analysis completely up to date
• Covers artificial channel controls such as weirs, spillways, and gates, and special topics such as transitions in supercritical flow and flow through culverts

Written in metric units throughout, this excellent learning tool for senior- and graduate-level students in civil and environmental engineering programs is also a useful reference for practicing civil and environmental engineers.

Laboratory physical models are a valuable tool for coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic engineering design solutions.This book is about the art and science of physical modeling as applied in coastal engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).

All papers have been peer reviewed and by scientific committee members with report about quality, content and originality. The target audience for this book includes scientists, engineers and practitioners involved in the field of numerical modelling in the water sector: flood management, natural resources preservation, hydraulic machineries, and innovation in numerical methods, 3D developments and applications.

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.

Contaminated sediments pose some of the most difficult site remediation issues. Contaminated sediments typically reside in spatially variable and dynamic systems subject to seasonal flow variations and episodic storm events. The volume of sediments that must be managed at particular sites often exceeds one million cubic meters, dwarfing many contaminated soil sites. These sediments are also associated with equally daunting volumes of water and efforts to remove the contamination typically entrains even more water. The environmental security of both NATO and partner countries is at risk due to the pervasive nature of sediment contamination of rivers, lakes and harbors. A NATO Advanced Research Workshop was convened in Bratislava in May 2005 to discuss current approaches to managing contaminated sediments and to identify research necessary to overcome outstanding problems.

In this text, drawn from presentations and discussion of that workshop, current approaches to the assessment and remediation of contaminated sediments will be discussed with the emphasis on in-situ management. Physical, chemical and biological approaches for the assessment and remediation of sediments are all addressed. Developing regulatory and strategic approaches are highlighted with a special emphasis on the potential for biological remediation for the management of contaminated sediments.

A growing proportion of the world's population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, which is facing cost increases in the global energy market. "Seawater Desalination" presents an overview of conventional and non-conventional technologies, with a particular focus on the coupling of renewable energies with desalination processes.

The first section of this book presents, in a technical but reader-friendly way, an overview of currently-used desalination processes, from thermal to membrane processes, highlighting the relevant technical features, advantages and disadvantages, and development potential. It also gives a rapid insight into the economic aspects of fresh water production from seawater.

The second section of the book presents novel processes which use Renewable Energies for fresh water production. From the first solar still evaporators, which artificially reproduced the natural cycle of water, technology has progressed to develop complex systems to harness energy from the sun, wind, tides, waves, etc. and then to use this energy to power conventional or novel desalination processes. Most of these processes are still at a preliminary stage of development, but some are already being cited as examples in remote areas, where they are proving to be valuable in solving the problems of water scarcity.

A rapid growth in these technologies is foreseen in the coming years. This book provides a unique foundation, within the context of present and future sustainability, for professionals, technicians, managers, and private and public institutions operating in the area of fresh water supply.

In determining the response of offshore structures, it is of utmost importance to determine, in the most correct manner, all factors which contribute to the total force acting on these structures. Applying the Morison formula (Morison et. al. , 1950) to calculate forces on offshore slender structures, uncertainties related to the understanding of the wave climate, the hydrodynamic force coefficients and the kinematics of ocean waves represent the most important contributions to the uncertainties in the prediction of the total forces on these structures (Haver and Gudmestad, 1992). Traditional calculation of forces on offshore structures involves the use of regular waves with the following non-linearities inco1porated use of regular wave theories inco1porating higher order terms use of Morison equation having a nonlinear drag term inclusion of the effect of the free surface by integrating all contributions to total forces and moments from the sea floor to the free surface of the waves In order to describe the sea more realistically, the ocean surface is to be described as an irregular sea surface represented by its energy spectrum. The associated decomposition of the sea surface is given as a linear sum of linear waves. The total force is found by integrating the contribution from all components in the wave spectrum to the free surface. The kinematics of each component must therefore be determined.

In the world of transportation, fatigue is a silent killer that can affect us all. Understanding fatigue, including how to manage it to minimize safety risk, is of great importance. However, while it is one thing to recognize that fatigue is a critical safety issue, it is quite another to set up a successful, scientifically informed fatigue risk management programme. This book is here to help. It has been carefully designed as a comprehensive reference point, bringing together international expertise from leaders in fatigue science, and showcasing valuable insights from transportation industry practitioners. The 40 authored chapters are divided into six sections, to better understand fatigue science, the consequences of fatigue in transportation, contributors to fatigue, managing fatigue and promoting alertness, real world case studies of fatigue management in practice, and future perspectives. While it is possible to read each chapter in isolation, most will be gained by reading the book as a whole. Each chapter starts with an abstract overview and concludes with summary bullet points, creating a handy "quick check" for key points. This accessible text is for those who are interested in supporting alert and safe transportation operations. It is suitable for professionals, transport managers, government advisors, policy makers, students, academics, and anyone who wants to learn more. All transport modes (road, rail, maritime and aviation) are considered. For anyone waking up to the complex challenge of fatigue management, this handbook is a must.

Global warming, melting polar caps, rising sea levels and intensifying wave-current action, factors responsible for the alarming phenomena of coastal erosion on the one hand and adverse environmental impacts and the high cost of 'hard' protection schemes, on the other, have created interest in the detailed examination of the potential and range of applicability of the emerging and promising category of 'soft' shore protection methods. 'Soft' methods such as beach nourishment, submerged breakwaters, artificial reefs, gravity drain systems, floating breakwaters, plantations of hydrophylous shrubs or even dry branches, applied mostly during the past 20 years, are recognised as possessing technical, environmental and financial advantageous properties deserving more attention and further developmental experimentation than has occured hitherto. On the other hand, 'hard' shore protection methods such as seawalls, groins and detached breakwaters, artefacts borrowed from port design and construction technology, no matter how well designed and well implemented they may be, can hardly avoid intensification of the consequential erosive, often devastating, effects on the down-drift shores. Moreover, they often do not constitute environmentally and financially attractive solutions for long stretches of eroding shoreline. Engineers and scientists practising design and implementation of shore defence schemes have been aware for many years of the public demand for improved shore protection technologies. They are encouraging efforts that promise enrichment of those environmentally sound and financially attractive methods that can be safely applied.

Two main areas of offshore activity are addressed in this book: Site investigation on assessment; and Applications and foundation engineering. The 37 contributions from a wide ranging group of international experts, are resulting from the Offshore Site Investigation and Foundation Behaviour Conference, London, U.K., September 1992. Adequate determination of site conditions can only be achieved by the integrated approach of using geological, geophysical and geotechnical data. Developments in data acquisition techniques are illustrated through case histories in the section on Geotechnical Sampling and Testing. In the section on Advanced Interpretation Techniques and Integrated Interpretations the state of the art of these topics is also illustrated by case histories. A review of foundation behaviour is presented in the section on Gravity Foundations, Foundation Performance Monitoring, Piling Research and Design Criteria. These topics are illustrated in the light of field experience and recent research, in particular that involving full-scale tests and monitoring. This book provides many illustrative figures and much pertinent information to exploration and marine geophysicists, petroleum and offshore engineers and for researchers working these fields.

In the past, boundary conditions in the building of dams have changed, as technological developments have been influential on dam planning, construction, operation and maintenance processes. It is ICOLD's mission to not only consider these developments but also adequately deal with environmental aspects and related infrastructure issues. Altered water cycles, more extreme weather conditions and an increasing number of natural hazards clearly affect the safe and economical operation of dams and reservoirs. Moreover, emission-free hydropower production as the most important form of "liquid" solar energy and the provision of water for irrigation and potable water supply is becoming more and more important to meet the world's fast growing demand for energy and food in a sustainable way. Dams and Reservoirs Under Changing Challenges covers subjects ranging from dam engineering through the benefits and drawbacks of dams, including the latest developments dealing with dams and reservoirs under changing environmental and socioeconomic conditions. It is a valuable resource for professional and dam engineers, water manager, governmental organizations and commercial consultants responsible for dam design and management.

The problem with the way the safety industry functions is three-fold: (1) the dysfunctional relationship between business and safety leaders, (2) the practice of Results-Based Safety, and (3) the creation of a false reality. This book presents an insightful and practical approach to how you can move your safety program from Results-Based to Behavior-Based Safety. The move involves understanding what motivates behavior, utilization of consequences, practicing the seven steps of performance coaching, creating accurate safety campaigns, and defining evidence of a healthy Behavior-Based Safety program-this is the other side of safety.. The text: Defines the four major motivations, explains how they work, and how safety leaders can use the right motivation for the right person to help them practice safe behavior Explains how to maximize the impact of reinforcement consequences and minimize punitive consequences in a way that is alingned with an individual's motivation Implements the seven steps of performance coaching conversations, how safety and business leaders can model fluency and frequency to shape behavior to habit strength Provides clearly defined evidence of a healthy Behavior-Based safety program by measuring outcome like locus of control, self-esteem, self-efficacy, and self-actualization Highlights the distinction between Results-Based Safety (RBS) anecdotal practices from the science of Behavior-Based Safety (BBS) methodology Showcases how the distinct difference between a mechanistic and organic culture, and how the four phenomena can be utilized to drive safety culture on purpose Discusses the importance of expanding from lagging indicators to leading indicators for robust metrics and predictability Addresses how the significant negative impact of "telling people what to do" and re-focuses on coaching people on "what to think" The book provides definitions, examples, and applications that focus on how safety and business leaders can influence the behavior of people, impact their culture, and support healthy relationships. It will serve as an ideal text for students, professionals, and researchers in the fields of ergonomics, human factors, human-computer interaction, industrial-organizational psychology, and computer engineering.

Coastal Flood Risk Reduction: The Netherlands and the U.S. Upper Texas Coast represents the culmination of a 5-year international research and education partnership funded by the US National Science Foundation (NSF) and more than 10 years of collaboration between Dutch and U.S. flood experts on the basic issue of how to protect society from growing flood risks. Multiple case studies integrating the fields of engineering, hydrology, landscape architecture, economics, and planning address the underlying characteristics of physical flood risks and their prediction; human communities and the associated built environment; physical, social, and built-environment variables; and mitigation techniques. In recognition of the lack of systematic research and the growing societal need to better understand flood impacts, this edited book provides an in-depth, comparative evaluation of flood problems and solutions in two key places: the Netherlands and the U.S. Upper Texas Coast. Both regions are extremely flood-prone and have experienced continual adverse impacts throughout their histories. For researchers in flood management, geographers, hydrologists, environmental studies, and social science as well as policymakers and decision-makers in flood management authorities and related industries, this book provides an essential resource.

The book describes the current state of former opencast mines in six countries. The remediation and reclamation of abandoned opencast mines are considered as a chance for new sustainable ecological, sociological and cultural developments in the regions concerned. The examples quoted from different countries allow the results of different remediation strategies to be compared. By way of conclusion, some recommendations are given at the end.

This special volume contains papers that are partly based on contributions to the symposium "Minesite Recultivation" wh ich was held at the Brandenburg Technical University in Cottbus, FRG in lune 1994. Ouring this symposium, various aspects of research into the recultivation of open-cast minesites were discussed. As a prime example, the symposium focussed on the recultivation (reclamation) of post-mining landscapes in the Lusatian lignite mining district of the former German 2 Oemocratic Republic (GOR). In this area, about 700 km have been devastated by open- cast mining during the last 70 years. Therefore, the research into recultivation has a long tradition in Lusatia, going back to the 1930's. Oue [0 the scientific isolation of the former GOR, most of the research results were not available to an international audience until now. This situation holds also true for other eastern countries. Hence, this special volume is a first step to fill this gap. The papers by Pietsch, Heinsdorf, and Katzur and Haubold-Rosar detail the Lusatian lignite mining district presenting an overview of recultivation research results and practical experiences related to the establishment of terrestrial and aquatic ecosystems in this region after mining. In particular, the amelioration and reforestation of extremely acid, sulfurous mine soils, the fertilization of forest stands under different mine site conditions and the site-specific recolonization and re vegetation strategies are described.
