A hydroinformatics system represents an electronic knowledge encapsulator that models part of the real world and can be used for the simulation and analysis of physical, chemical and biological processes in water systems, in order to achieve a better management of the aquatic environment. Thus, modelling is at the heart of hydroinformatics. The theory of nonlinear dynamics and chaos, and the extent to which recent improvements in the understanding of inherently nonlinear natural processes present challenges to the use of mathematical models in the analysis of water and environmental systems, are elaborated in this work. In particular, it demonstrates that the deterministic chaos present in many nonlinear systems can impose fundamental limitations on our ability to predict behaviour, even when well-defined mathematical models exist. On the other hand, methodologies and tools from the theory of nonlinear dynamics and chaos can provide means for a better accuracy of short-term predictions as demonstrated through the practical applications in this work.

Computational hydraulics and hydrologic modeling are rapidly developing fields with a wide range of applications in areas ranging from wastewater disposal and stormwater management to civil and environmental engineering. The fields are full of promise, but while an abundance of literature now exists, it contains a plethora of new terms that are not always defined.

Computational Hydraulics and Hydrology: An Illustrated Dictionary defines more that 4000 basic terms and phrases related to water conveyance with emphasis on computational hydraulics and hydrologic modeling. Compiled by Nicolas G. Adrien, a noted consulting engineer with three decades of experience, this dictionary includes detailed references to actual modeling studies, nearly 100 illustrations, 150 equations and formulas, and many notations. It also includes a chapter of application examples and another containing more than 6000 other related terms with a list of resources where interested readers can find further definitions.

Other dictionaries and glossaries related to these areas tend to be either dated or much narrower in scope. This dictionary offers broad, practice-based coverage of terms culled directly from the latest texts, references, and actual engineering reports. Computational Hydraulics and Hydrology: An Illustrated Dictionary stands alone in providing ready access to the vocabulary of these subjects.

During the life of a dam, changes in safety standards, legislation and land use will inevitably occur, and functional deterioration may also appear. To meet these challenges, these Proceedings from a panel of international experts assess, define and re-evaluate the design criteria for the construction of dams and the many attendant issues in on-going maintenance and management. Authors include international specialists: academics, professionals and those in local government, utilities and suppliers. Practitioners from these same fields will find the book a useful tool in acquiring a comprehensive knowledge of managing and retrofitting dams, so that they can continue to meet society's needs.

The book describes in twelve chapters the modern tools available for the detection and prevention of leaks from dams and reservoirs, including water chemistry, isotope analyses, artificial tracers, permeability tests, geophysical methods and techniques for the localization of water flows both inside the reservoir and boreholes. Numerous case studies are presented corresponding to studies of more than thirty dams performed by researchers in eighteen different countries.

The Proceedings of the Symposium at World Water Day, 2001 presents a discussion of dams and dikes. Various speakers considered the benefits and drawbacks of dams, and there was discussion about why it is that people are against dams in specific situations, and how such situations may be resolved. Solutions are suggested to such controversies. These proceedings contain the full text of the presentations. They will be a useful resource for decision-makers and planners of future projects. This work highlights the international nature of these important hydraulic engineering strucures and both their technology and social implications.

Frequent drought events, recently occurred in different Mediterranean regions, have highlighted a general inadequacy of the current strategies applied to mitigate negative impacts of such phenomenon on different water sectors. In particular, the lack of timely drought monitoring systems, the difficulty in transferring advanced methodologies for the assessment of drought risk to the institutions responsible for water resources management, as well as the complexity in defining simple and objective criteria to select and implement appropriate mitigation measures, represent the main limits to an efficient drought management policy.

These key issues have been tackled by universities and public agencies involved in the EU projects Sedemed and Sedemed II (Programme Interreg IIIB MEDOCC), aimed at the definition of an integrated network for real time monitoring of drought, the development of common methodologies for drought analysis and forecasting, as well as of mitigation strategies for the Mediterranean countries.

This book presents the main outcomes of such projects with a specific focus on: drought monitoring and forecasting techniques at different spatial scales (Part I), new agrometeorological indices and remote sensing technique for drought identification (Part II), tools to improve surface water resources management under drought condition (Part III), methods for monitoring and management groundwater (Part IV) and mitigation strategies to prevent or face drought impacts (Part V).

The applications of stochastic methods in design by reliability include the better utilisation of hydrological information. With statistical methods one can evaluate the safety component of hydraulic systems. Based on these, extra safety features can be added to ensure the reliable performance of an hydraulic system. One such example is the design of a dam, which features a number of random variables, each with a very distinct and quite different probability function. This book reports on developments in stochastic hydraulics across a wide range of applications, including river hydraulics, sediment transportation, waves and coastal processes, hydrology, hydraulic works and structure, and environmental hydraulics.

This volume looks at recent scientific knowledge and innovative techniques concerning environmental matters. The proceedings focus on topics such as hydraulic protection of territory and defence, utilization of water resources, architecture and planning of fluival/coastal landscape and much more.

This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.

Besides giving an historical introduction to embankment dams the book describes the need for instrumentation, planning procurement and installation practices of instruments. The significance of visual inspection and techniques, of monitoring various parameters, seepage, pore pressure, surface and internal displacements, earth pressures and seismic behaviour, through instrumentation has been described. Collection and processing of data and their use for back analysis to check stability of a dam at various stages of construction and reservoir filling have been suggested. In addition to case histories quoted in various chapters, an exclusive chapter on select case histories has been added which describes the conventional and latest instruments that are being used and methods adopted for installation, monitoring and analyses of data.

Man's control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.

Imported water has transformed the Golden State's environment and quality of life. In the last one hundred years, land ownership patterns and real estate boosterism have dramatically altered both urban and rural communities across the entire state. The key has been water from the Eastern Sierra, the Colorado River and, finally, Northern California rivers. Whoever brings the water, brings the people wrote engineer William Mulholland, whose leadership began the process of water irrigating unlimited growth. Using first-person voices of Californians to reveal the resulting changes, Carle concludes that the new millennium may be the time to stop drowning the California dream.

With extensive use of oral histories, contemporary newspaper articles, and autobiographies, Carle provides a rich exploration of the historic change in California, showing that imported water has shaped the pattern of population growth in the state. Water choices remain the primary tool, he claims, for shaping California's future. The state's damaged environment and reduced quality of life can be corrected if Californians will step out of their historic pattern and embrace limited water supplies as a fact of life in this naturally dry region.

Sediment transport, two-phase flow and loose boundary hydraulics are some of the problems of interaction between fluid flow (water or air) and boundaries that may be non-cohesive (alluvial) or cohesive. Unlike in classical hydraulics, these boundaries can change their shape and texture with changing flow conditions. Some of the material from the boundaries may be entrained into the flow, or sediment may be added to the flow, sometimes by tributaries as suspended matter. One instance is the transport of granular material in pipelines Since the changing boundaries are the central feature of most flow processes in nature, the term loose boundary hydraulics is here introduced.
Examines the physical processes involved in the interaction between air or liquid flow and the solid boundaries of its movement, showing how the properties of each material affect the dynamics between them.

Low-lying countries, such as the Netherlands, are strongly dependent on good and safe sea defences. In the past, the design of dikes and revetments was mostly based on vague experience, rather than on general valid calculation methods. The demand for reliable design methods for protective structures has, in the Netherlands, resulted in increased research in this field. These contributions have been prepared by Dutch experts participating in the study groups of the Technical Advisory Committee on Water Defences. The book opens with an outline of general strategy and methodology on sea defences, illustrated in the following chapters by technical information on specific items and Dutch experience, and it ends with more general aspects such as probabilistic approach, integral (multifunctional) design, management & safety assessment. Together, these chapters provide an almost complete technical overview of the items needed for the design and maintenance of dikes and revetments. The enclosed CRESS-program allows for an initial estimation of hydraulic loads and preliminary design.

This text covers topics such as: hydrodynamic and water quality modeling; jets and plumes; turbulent sheer flows; air-water interaction; water quality models; environmental impact studies/Three Gorges project; water quality mangement; and eco hydraulics and river hydraulics.
