Download or read book Urban Water Resources Toolbox written by Leif Wolf and published by IWA Publishing. This book was released on 2007-01-19 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holistic but applicable approaches are urgently needed to help plan long-term, cost-effective and sustainable urban water management systems. Groundwater is a central element in the urban water cycle of all cities located on aquifers, yet it remains inadequately integrated into urban water management practices. This book describes holistic approaches for quantification and balancing of urban water and solute fluxes that have been developed by the joint Euro-Australian research project AISUWRS. The new tools comprise a chain of interconnected models that link urban water supply, urban drainage and urban groundwater resources. These include a new sewer exfiltration, model that is based on pipe asset conditions which permits flows to the environment to be estimated. The book provides details on the further processing of this information through the unsaturated zone down to aquifer, where numerical groundwater flow and transport models are applied. Concise documentation is provided on each of the models. The practicability of applying the chain of models was tested by applying it in four case study cities in Australia, Germany, Slovenia and the United Kingdom that have diverse conditions in terms of hydrogeologic setup, climate and data availability. This permitted additional validation by field investigations, including problem-oriented monitoring campaigns aimed at assessing the impact of wastewater practice on groundwater. The book provides guidance and examples of the application of multilevel piezometers, on adapted monitoring strategies, and the use for interpretation purposes of microbiological parameters, pharmaceutical residues and related marker species. The socio-economic analysis in the case study cities sometimes uncovered distinctively different problem perceptions and priorities, both in the groups of experts responsible for the water management and with the remaining stakeholders. The AISUWRS project has developed tools to foster these urgently required deliberation processes. Methodologies for formal sustainability assessment with a triple bottom line background were also elaborated and tested during the case studies. The case studies have shown that the approach is valid and constitutes an important step towards integrated urban water management.

Download or read book Modeling the Effects of Agricultural Management Practices on Groundwater Quality and Quantity written by José Arumí Ribera and published by . This book was released on 2000 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research is to develop a groundwater model that will be used in the integrated model described previously. The general objetive of the research is to develop a methodology that permits the assessment of the impact on groundwater quality and quantity produce by changes in recharge, nitrate leahing and pumping rates. The methodology developed in this research is based on the use of three numerical simulation models linked in a serial connection (Figure 2.3). The first component is the davose zone model, which simulates the effect that the vadose zone has on water and solute recharge to the grandwater system. The second component is a groundwater flow model that is used to calculate the dynamic behavior of the groundwater system. The last component is the solute transport model that facilitates the study of changes in groundwater quality. The integrated modeling project is being developed in modules. For that reason, neither the watershed-plant nor the optimal control models are available at this time. To explore the applicability of the methodology developed in this research, we decided to study the potential effect that the MSEA Project has on groundwater quality.

This book was released on 2012-12-06 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Pollution is a subject of growing concern in our industrial world. The environmental problems caused by the increase of pollutant loads dis charged into natural water systems have led the scientific community to pursue studies capable of relating the pollutant discharge with changes in the water quality. The results of these studies are permitting industries to employ more efficient methods of controlling and treating the waste loads, and water authorities to enforce more strict legislation regarding this matter. The present book contains edited versions of the papers presented at the First International Conference on Water Pollution (Modelling, Measuring and Prediction), held in Southampton, England, in September 1991. Its contents, which reflect the interdisciplinarity of the subject, are divided into four parts, each consisting of a keynote address and several invited and contributed papers: 1. Mathematical models (Keynote speaker: Prof. R.A. Falconer, Univer sity of Bradford, USA) 2. Data acquisition/monitoring/measurement (Keynote speaker: Dr. A. Plata Bedmar, IAEA, Austria) 3. Waste disposal and wastewater treatment (Keynote speaker: Prof. D.R.F. Harleman, MIT, USA) 4. Chemical and biological problems (Keynote speaker: Dr. E.I. Hamil ton, Environmental consultant, UK) Although the papers have been typographically edited they have been re produced directly from material submitted by the authors, and their content is a reflection of the authors' research and opinion.

Book excerpt: Water Pollution XII contains the proceedings of the 12th International Conference in the series of Modelling, Monitoring and Management of Water Pollution. The book will be of interest to scientists, managers and academics from different areas of water contamination. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies required the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential. Topics covered include: Water quality; Groundwater and aquifer issues; Environmental monitoring and control; Water management; Remediation; Pollution prevention; Lakes and rivers; Agricultural contamination; Wastewater treatment and management; Offshore pollution and oil spills; Emerging technologies; Biosensors and biosystems; Health risk studies; Modelling and simulation; Pharmaceutical and pesticides pollution; Monitoring and modelling integration; Risk assessments; Socio-economic-political consequences; Education and training.

Download or read book Water Quality Indices written by Tabassum Abbasi and published by Elsevier. This book was released on 2012-03-10 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

This book was released on 2014-06-18 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogeological evolution and three-dimensional numerical modeling were investigated in an urban area of Beijing. The main conclusion illustrate that hydrogeochemical modeling, geological statistics and spatial analysis on GIS can be applied to jude and measure the anthropogenic influence on the chemical composition of groundwater, as was assessment of stable isotope ratios approach in combination with chemical and hydrogeological data revealed that wastewater is the prevailing source of nitrogen. Moreover investigations using laboratory columns and field observations revealed that clay controls the concentration of cations, silica, and chloride ions in groundwater, indicating that clay layer is an important factor involved in control of groundwater quality. Then MODFLOW model was able to represent the negative impacts caused by excessive extraction of groundwater. PHT3D model was also able to quantify the influence of various land use functions on groundwater quality and deduce geochemical processes occurring in the aquifers. Finally, a novel conceptual model for an urban area that can be used in the future to evaluate site remediation scenarios was developed as part of this work.
