Water Resources Management And Modeling

Water resources play an essential role in all aspects of human life and activities. All living organisms need water for survival. Due to increased demand for water, appropriate water resources management should be established. This book covers various aspects of water resources management, including their use for different purposes and impacts of natural factors and anthropogenic pressures on water resources. Climate changes affect water resources, causing floods and droughts. All human activities such as water supply, irrigation, navigation, hydropower, tourism and recreation use water resources. The natural and anthropogenic impacts cause a decline in water quantity and the degradation of water quality. Water resources are especially important in protected areas and management of them in these areas is a specific challenge. Adequate water resources management should address all water related issues, to establish an institutional and legal framework, as well as the cooperation of all relevant actors in this field at national and international level. Water reuse, such as wastewater management is also an important challenge. This book provides some models and methods which are used for water resources estimation, their vulnerability and exposure to natural and anthropogenic influences. Taking into account various aspects of water related topics, application of diverse models and methods in different geographical areas, the book Water Resources Management: Methods, Applications and Challenges could help policy and decision makers as well as other stakeholders in finding the solutions of some water related problems.

This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.

Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources. Meeting the challenges and the impact of climate change on water resources is also discussed in the book. Most chapters give insights into the interpretation of field information, development of models, the use of computational models based on analytical and numerical techniques, assessment of model performance and the use of these models for predictive purposes. It is written for the practicing professionals and students, mathematical modelers, hydrogeologists and water resources specialists.

This book describes concepts and tools needed for water resources management, including methods for modeling, simulation, optimization, big data analysis, data mining, remote sensing, geographical information system, game theory, conflict resolution, System dynamics, agent-based models, multiobjective, multicriteria, and multiattribute decision making and risk and uncertainty analysis, for better and sustainable management of water resources and consumption, thus mitigating the present and future global water shortage crisis. It presents the applications of these tools through case studies which demonstrate its benefits of proper management of water resources systems. This book acts as a reference for students, professors, industrial practitioners, and stakeholders in the field of water resources and hydrology.

Sustainable Water Resources Management presents the most current thinking on the environmental, social, and political dimensions of sustainably managing the water supply at local, regional, or basin levels.

Covering the more recent advances in Modelling, Planning, Management and Negotiations for Integrated Water Resource Management, this text brings together knowledge and concepts from Hydrology, System Analysis, Control Theory, Conflict Resolution, and Decision and Negotiation Theory. Without compromising on mathematical rigour, the book maintains a fine line between theory and application, methodology and tools, avoiding getting locked into excessively theoretical and formal development of the issues discussed. The non-technical aspects of water resource systems (such as societal, political and legal concerns) are recognized throughout the book as having a great, if not fundamental, importance to reaching an agreed-upon decision; they are therefore integrated into the more technical and mathematical issues. The book provides a unified, coordinated and comprehensive framework that will facilitate the increasingly appropriate application of the Integrated Water Resource Management paradigm by current and future practising professionals, decision-makers and scientists. · Integration of technical modelling and control aspects with participatory and decision-making issues· Insightful and comprehensive treatment of theoretical contents, supported by practical examples· A wide collection of exercises and project examples based on real-world case studies (with complete solutions)

The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

This book is divided into four parts. The first part, Preliminaries, begins by introducing the basic theme of the book. It provides an overview of the current status of water resources utilization, the likely scenario of future demands, and advantages and disadvantages of systems techniques. An understanding of how the hydrological data are measured and processed is important before undertaking any analysis. The discussion is extended to emerging techniques, such as Remote Sensing, GIS, Artificial Neural Networks, and Expert Systems. The statistical tools for data analysis including commonly used probability distributions, parameter estimation, regression and correlation, frequency analysis, and time-series analysis are discussed in a separate chapter. Part 2 Decision Making, is a bouquet of techniques organized in 4 chapters. After discussing optimization and simulation, the techniques of economic analysis are covered. Recently, environmental and social aspects, and rehabilitation and resettlement of project-affected people have come to occupy a central stage in water resources management and any good book is incomplete unless these topics are adequately covered. The concept of rational decision making along with risk, reliability, and uncertainty aspects form subject matter of a chapter. With these analytical tools, the practitioner is well equipped to take a rational decision for water resources utilization. Part 3 deals with Water Resources Planning and Development. This part discusses the concepts of planning, the planning process, integrated planning, public involvement, and reservoir sizing. The last part focuses on Systems Operation and Management. After a resource is developed, it is essential to manage it in the best possible way. Many dams around the world are losing some storage capacity every year due to sedimentation and therefore, the assessment and management of reservoir sedimentation is described in details. No analysis of water resources systems is complete without consideration of water quality. A river basin is the natural unit in which water occurs. The final chapter discusses various issues related to holistic management of a river basin.
