This book was released on 2020-04-22 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical models of flow and transport processes are heavily employed in the fields of surface, soil, and groundwater hydrology. They are used to interpret field observations, analyze complex and coupled processes, or to support decision making related to large societal issues such as the water-energy nexus or sustainable water management and food production. Parameter estimation and uncertainty quantification are two key features of modern science-based predictions. When applied to water resources, these tasks must cope with many degrees of freedom and large datasets. Both are challenging and require novel theoretical and computational approaches to handle complex models with large number of unknown parameters.

This book was released on 1998-10-31 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the pioneering work of Shannon in the late 1940's on the development of the theory of entropy and the landmark contributions of Jaynes a decade later leading to the development of the principle of maximum entropy (POME), the concept of entropy has been increasingly applied in a wide spectrum of areas, including chemistry, electronics and communications engineering, data acquisition and storage and retreival, data monitoring network design, ecology, economics, environmental engineering, earth sciences, fluid mechanics, genetics, geology, geomorphology, geophysics, geotechnical engineering, hydraulics, hydrology, image processing, management sciences, operations research, pattern recognition and identification, photogrammetry, psychology, physics and quantum mechanics, reliability analysis, reservoir engineering, statistical mechanics, thermodynamics, topology, transportation engineering, turbulence modeling, and so on. New areas finding application of entropy have since continued to unfold. The entropy concept is indeed versatile and its applicability widespread. In the area of hydrology and water resources, a range of applications of entropy have been reported during the past three decades or so. This book focuses on parameter estimation using entropy for a number of distributions frequently used in hydrology. In the entropy-based parameter estimation the distribution parameters are expressed in terms of the given information, called constraints. Thus, the method lends itself to a physical interpretation of the parameters. Because the information to be specified usually constitutes sufficient statistics for the distribution under consideration, the entropy method provides a quantitative way to express the information contained in the distribution.

Book excerpt: This volume is a collection of a selected number of articles based on presentations at the 2005 L’Aquila (Italy) Summer School on the topic of “Hydrologic Modeling and Water Cycle: Coupling of the Atmosphere and Hydrological Models”. The p- mary focus of this volume is on hydrologic modeling and their data requirements, especially precipitation. As the eld of hydrologic modeling is experiencing rapid development and transition to application of distributed models, many challenges including overcoming the requirements of compatible observations of inputs and outputs must be addressed. A number of papers address the recent advances in the State-of-the-art distributed precipitation estimation from satellites. A number of articles address the issues related to the data merging and use of geo-statistical techniques for addressing data limitations at spatial resolutions to capture the h- erogeneity of physical processes. The participants at the School came from diverse backgrounds and the level of - terest and active involvement in the discussions clearly demonstrated the importance the scienti c community places on challenges related to the coupling of atmospheric and hydrologic models. Along with my colleagues Dr. Erika Coppola and Dr. Kuolin Hsu, co-directors of the School, we greatly appreciate the invited lectures and all the participants. The members of the local organizing committee, Drs Barbara Tomassetti; Marco Verdecchia and Guido Visconti were instrumental in the success of the school and their contributions, both scienti cally and organizationally are much appreciated.

Download or read book Flood Risk Assessment and Management written by Andreas H. Schumann and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flood catastrophes which happened world-wide have shown that it is not sufficient to characterize the hazard caused by the natural phenomenon "flood" with the well-known 3M-approach (measuring, mapping and modelling). Due to the recent shift in paradigms from a safety oriented approach to risk based planning it became necessary to consider the harmful impacts of hazards. The planning tasks changed from attempts to minimise hazards towards interventions to reduce exposure or susceptibility and nowadays to enhance the capacities to increase resilience. Scientific interest shifts more and more towards interdisciplinary approaches, which are needed to avoid disaster. This book deals with many aspects of flood risk management in a comprehensive way. As risks depend on hazard and vulnerabilities, not only geophysical tools for flood forecasting and planning are presented, but also socio-economic problems of flood management are discussed. Starting with precipitation and meteorological tools to its forecasting, hydrological models are described in their applications for operational flood forecasts, considering model uncertainties and their interactions with hydraulic and groundwater models. With regard to flood risk planning, regionalization aspects and the options to utilize historic floods are discussed. New hydrological tools for flood risk assessments for dams and reservoirs are presented. Problems and options to quantify socio-economic risks and how to consider them in multi-criteria assessments of flood risk planning are discussed. This book contributes to the contemporary efforts to reduce flood risk at the European scale. Using many real-world examples, it is useful for scientists and practitioners at different levels and with different interests.

Download or read book Uncertainties in Environmental Modelling and Consequences for Policy Making written by Philippe Baveye and published by Springer Science & Business Media. This book was released on 2009-05-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modelling has become in recent years an essential tool for the prediction of environmental change and for the development of sustainable policies. Yet, many of the uncertainties associated with modelling efforts appear poorly understood by many, especially by policy makers. This book attempts for the first time to cover the full range of issues related to model uncertainties, from the subjectivity of setting up a conceptual model of a given system, all the way to communicating the nature of model uncertainties to non-scientists and accounting for model uncertainties in policy decisions. Theoretical chapters, providing background information on specific steps in the modelling process and in the adoption of models by end-users, are complemented by illustrative case studies dealing with soils and global climate change. All the chapters are authored by recognized experts in their respective disciplines, and provide a timely and uniquely comprehensive coverage of an important field.

Download or read book Assessing and Managing Groundwater in Different Environments written by Jude Cobbing and published by CRC Press. This book was released on 2019-01-22 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers is a snapshot of modern hydrogeology in which highly technical methods and approaches sit side-by-side with overlapping legal, social, organisational, institutional and governance considerations. Groundwater is integral to many human and environmental systems. Indeed, there appears to be a growing realisation that some of the most pressing physical problems in the field of hydrogeology - over-abstraction, salinization or pollution - can only really be solved by taking a multi-disciplinary approach to the issues that takes all other related professions into account. Whilst a ‘technical’ solution may be readily deciphered, the larger challenge usually lies in the sustainably-funded and widely-accepted implementation of that measure. This book ranges from discussion and debate on the hot topic of hydraulic fracturing of wells or ‘fraccing’ for shale gas and its potential to disrupt groundwater systems, to the application of highly technical modelling procedures to help solve complex, real world problems. It is a window on the preoccupations of modern hydrogeologists and an insight into the way in which hydrogeological techniques and methods are being holistically adapted to address problems in the real world. This book is targeted at professional hydrogeologists, sociologists, experts in governance, law and policy as well as ecologists and other professionals that nowadays all sit alongside groundwater understanding. The book will also appeal to politicians, resource managers, regulators and others interested in sustainable water supply.

Download or read book Water Resources Management and Sustainability written by Pankaj Kumar and published by Springer Nature. This book was released on 2022-02-02 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is the elixir of life and is crucial for sustainable development. Earlier, it was considered to be a limitless or at least a fully renewable natural resource. During the past 20 years, however, there has been tremendous pressure on this precious natural resource mainly due to rapid urbanization, industrialization and the increase in the human population. Together, these have resulted in increasing demand for irrigation, industrial, and household purposes to meet supply-chain requirements. Keeping in mind the scarcity of available water resources in the near future and its impending threats, it has become imperative on the part of scientists in hydrology and allied disciplines such as geography, landscape planning, sustainability science etc. Regional planners and supply chain management experts also must be involved in studying the spatial and temporal nature of the growing demand for water and the future availability for its judicial use and sustainable management. A primary intent of the book is to provide comprehensive scientific knowledge base on water resource management and sustainability. It covers geo-engineering and scientific problems, case studies, and sustainable solutions in the water resources management domain. Additionally and of equal importance, the chapters of the book provide in-depth coverage on water resource vulnerability, water quality, wastewater treatment, application of remote sensing and geographical information systems hydrological modeling and harvesting, climate variability and runoff, sediment discharge and irrigation planning, community participation in water governance, internet of things and machine learning applications for sustainable water resources management. This practical, state-of-the-art reference book is a valuable resource for students, researchers, scientists, policymakers, spatio-temporal designers of water resource systems, various stake holders interested in hydro-climatology and sustainable water resources management.

Download or read book River Water Quality Model written by P. Reichert and published by IWA Publishing. This book was released on 2001-08-31 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Scientific and Technical Report (STR) presents the findings of the IWA Task Group on River Water Quality Modelling (RWQM). The task group was formed to create a scientific and technical base from which to formulate standardized, consistent river water quality models and guidelines for their implementation. This STR presents the first outcome in this effort: River Water Quality Model No. 1 (RWQM1). As background to the development of River Water Quality Model No.1, the Task Group completed a critical evaluation of the current state of the practice in water quality modelling. A major limitation in model formulation is the continued reliance on BOD as the primary state variable, despite the fact BOD does not include all biodegradable matter. A related difficulty is the poor representation of benthic flux terms. As a result of these limitations, it is impossible to close mass balances completely in most existing models. These various limitations in current river water quality models impair their predictive ability in situations of marked changes in a river's pollutant load, streamflow, morphometry, or other basic characteristics. RWQM 1 is intended to serve as a framework for river water quality models that overcome these deficiencies in traditional water quality models and most particularly the failure to close mass balances between the water column and sediment. To these ends, the model incorporates fundamental water quality components and processes to characterise carbon, oxygen, nitrogen, and phosphorus (C, O, N, and P) cycling instead of biochemical oxygen demand as used in traditional models. The model is presented in terms of process and components represented via a 'Petersen stoichiometry matrix', the same approach used for the IWA Activated Sludge Models. The full RWQM1 includes 24 components and 30 processes. The report provides detailed examples on reducing the numbers of components and processes to fit specific water quality problems. Thus, the model provides a framework for both complicated and simplified models. Detailed explanations of the model components, process equations, stoichiometric parameters, and kinetic parameters are provided, as are example parameter values and two case studies. The STR is intended to launch a participatory process of model development, application, and refinement. RWQM1 provides a framework for this process, but the goal of the Task Group is to involve water quality professionals worldwide in the continued work developing a new water quality modelling approach. This text will be an invaluable reference for researchers and graduate students specializing in water resources, hydrology, water quality, or environmental modelling in departments of environmental engineering, natural resources, civil engineering, chemical engineering, environmental sciences, and ecology. Water resources engineers, water quality engineers and technical specialists in environmental consultancy, government agencies or regulated industries will also value this critical assessment of the state of practice in water quality modelling. Key Features presents a unique new technical approach to river water quality modelling provides a detailed technical presentation of the RWQM1 water quality process model gives an informative critical evaluation of the state of the practice in water quality modelling, and problems with those practices provides a step by step procedure to develop a water quality model Scientific & Technical Report No. 12
