This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the International Institute for Applied Systems Analysis began its study of water quality modeling and management in 1977, it has been interested in the relations between uncertainty and the problems of model calibration and prediction. The work has focused on the theme of modeling poorly defined environmental systems, a principal topic of the effort devoted to environmental quality control and management. Accounting for the effects of uncertainty was also of central concern to our two case studies of lake eutrophication management, one dealing with Lake Balaton in Hungary and the other with several Austrian lake systems. Thus, in November 1979 we held a meeting at Laxenburg to discuss recent method ological developments in addressing problems associated with uncertainty and forecasting of water quality. This book is based on the proceedings of that meeting. The last few years have seen an increase in awareness of the issue of uncertainty in water quality and ecological modeling. This book is relevant not only to contemporary issues but also to those of the future. A lack of field data will not always be the dominant problem for water quality modeling and management; more sophisticated measuring techniques and more comprehensive monitoring networks will come to be more widely applied. Rather, the important problems of the future are much more likely to emerge from the enhanced facility of data processing and to concern the meaningful interpretation, assimilation., and use of the information thus obtained.

Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 4.0 license. 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.

Download or read book A GIS Based Water Quality Assessment and Pollution Control Planning Approach for Lake Management WQAPCP written by Li Kai Geng and published by . This book was released on 2017 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many lakes are receiving large volumes of contaminants from agricultural discharges, industrial emissions and municipal wastewater, which causes significant surface water pollution. The adverse environmental and health effects of lake contamination are a primary concern in environmental management. Water quality assessment methods and pollution control planning models are useful tools for researchers and decision-makers to protect ecological environments and develop local economies. Also spatial information technologies such as Geographic Information Systems (GIS) make it possible to manage water bodies with more detailed location-based information. The goal of this thesis is to develop a GIS-based water quality assessment and pollution control planning approach for lake management (WQAPCP), which includes the following components: (1) evaluation of water quality based on four index methods with inter-comparisons; (2) pollution control planning for a lake system based on an integration of pollutant distribution simulation and optimization models along with water quality index measures; (3) GIS technology to help implementing water quality assessment and lake contamination control optimization by creating displayed maps of the study results to provide spatial support for decisions.Several water quality evaluation methods are first presented in this thesis within the GIS framework to examine water quality index models, including the US Oregon water quality index (OWQI), the Canadian water quality index (CWQI), the Chinese single-factor water quality index (CNWQI-S) and the Chinese comprehensive water quality index (CNWQI-C) methods. These index methods are applied to assess the water quality of a real case. The assessment results are presented in the form of GIS maps containing the spatial distribution of the water quality levels and their ranking. Through an example of sensitivity analysis and comparison of four sets of water quality assessment results, the parameters with the most significant influence on lake water quality are identified and the most suitable method of water quality evaluation is put forward to support future lake management.Subsequently, this thesis develops a simulation-optimization approach by integrating lake water quality simulation and lake pollution control optimization. A contaminant dispersion simulation is first conducted to provide input for the optimization study. Particularly, a single-objective programming (SOP) model and a multi-objective programming (MOP) model are developed, applied, and compared to support effective lake water contamination control planning under different lake management scenarios. Three periods and a set of significant levels are considered in the real case study to provide a comprehensive dynamic modeling and optimization analysis of lake pollution control through the simulation-optimization approach. Based on the developed optimization method and the case study results, the OWQI and CNWQI-C methods are utilized to help formulating the effective measures for lake water quality management. GIS technology is employed in this study to link the water quality assessment approaches and the lake pollution control optimization. By integrating the relevant data and creating visualized maps of the study results, GIS plays an important role in extending the modeling and assessment results for the lake water quality management with spatial geo-references.

Download or read book Water Quality Modelling for Rivers and Streams written by Marcello Benedini and published by Springer. This book was released on 2013-02-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the Water Framework Directive in the European countries is to achieve a “good status” of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling. Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants. To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance. All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.
Download or read book Water Quality Modelling of Northern Lakes Case Study Egyptian Northern Lakes written by Noha Donia and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the shallow coastal lakes are not only one of the most valuable ecosystems in the world but also some of the most threatened as they receive the wastewater discharged from the watershed, it was important to develop a more detailed modelling component for the lake system. Nowadays, relative to the present advances in computational sciences, hardware and software, improvement in rivers, catchments and lakes modelling has been only modest since the past few decades. The main objective of the study is to examine and evaluate the impact of alternative water quality management practices in the selected drainage catchment, and their effect on the environmental condition of the lake as an important component of the watershed. A hydrodynamic and water quality model was used to study the current status of coastal lakes subject to the discharges and pollution loadings coming from the agricultural drains and the point sources discharge directly to the lake, through simulating the flow circulation inside the main basin of the lake, the transport and advection of the pollutants due to the effluent discharges from drains and other sources of pollutants, and identify and develop the most critical surface drainage water quality indicators to simulate and predict the temporal and spatial variation of pollution.

Download or read book Water Quality Modeling That Works written by Wu-Seng Lung and published by Springer Nature. This book was released on 2022-01-17 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical guidance for environmental engineers and scientists charged with assessing the cause-and-effect of pollutants in receiving water systems. Instead of blindly running models, which is a practice seen too often in today’s field that can result in results with uncertainty, modelers must first understand the physical insights of the specific water systems in order to properly calibrate the parameters of the models. This book reinforces the critical importance of properly understanding the physical attributes of water systems by drawing on the author’s extensive experience in modeling with strong data support. This is also what sets this book apart from the volumes currently available in the water quality modeling field – nearly all other books in the field are categorized as textbooks, and unlike this book, offer few practical examples or exercises to follow. Environmental engineers and scientists engaged in quantifying the water quality impacts of pollutants to specific water systems will find this book valuable in their day-to-day practices. This book is a necessary volume for water quality engineers and scientists to consult for the regulatory planning and management of water systems
Download or read book Water Quality Modeling written by Brian Henderson-Sellers and published by CRC Press. This book was released on 1991-03-14 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents the first decision support book aimed at water quality management for lakes and reservoirs. The book offers both a retrospective view (in terms of summarizing past work) and a prospective view (in terms of forecasting the greater use of such models as part of much needed environmental decision support systems). The concepts of lake and reservoir simulation modeling, as well as the concepts of decision support systems, formalized within the information systems discipline, are supported by a wealth of case studies. Case studies in the early chapters concentrate more on the physical (dynamic and thermodynamic) parameters, while later chapters stress the need for a more detailed representation of the biology and chemistry. Other case studies emphasize the management use of the model. New tools and concepts are also presented to facilitate the transfer of case studies presented in this volume from the arena of research to that of operational and planning management. Water quality managers, research scientists, and water engineers will find this volume an exciting source of new ideas and concepts.
Download or read book Social and Ecological System Dynamics written by Krystyna Stave and published by Springer. This book was released on 2017-04-06 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a social—ecological system description and feedback analysis of the Lake Tana Basin, the headwater catchment of the Upper Blue Nile River. This basin is an important local, national, and international resource, and concern about its sustainable development is growing at many levels. Lake Tana Basin outflows of water, sediments, nutrients, and contaminants affect water that flows downstream in the Blue Nile across international boundaries into the Nile River; the lake and surrounding land have recently been proposed as a UNESCO Biosphere Reserve; the basin has been designated as a key national economic growth corridor in the Ethiopian Growth and Transformation Plan. In spite of the Lake Tana Basin’s importance, there is no comprehensive, integrated, system-wide description of its characteristics and dynamics that can serve as a basis for its sustainable development. This book presents both the social and ecological characteristics of the region and an integrated, system-wide perspective of the feedback links that shape social and ecological change in the basin. Finally, it summarizes key research needs for sustainable development.
