Book excerpt: ASCE/EWRI Standard 50-08 provides current guidelines for fitting saturated hydraulic conductivity using probability density functions. Standard ASCE/EWRI 51-08 addresses the calculation of effective saturated hydraulic conductivity (Ke or Kew) in local-scale groundwater flow, whether or not it is isotropic. Both Standards are bound in the same volume. These are the first in an anticipated series of standards that will address the knowledge of probabilistic characterization and behavior of saturated groundwater conductivity. Saturated hydraulic conductivity is critical in effectively and accurately measuring groundwater flow and transport of contaminants. All saturated hydraulic conductivity measurements are subject to variability even in the most geologically homogeneous aquifers caused by local fluctuations in an aquifer s textural characteristics. Averages of these fluctuations constitute a set of values that can be subsumed into a more general probabilistic description of the sample by means of a probability density function. Applying probabilistic procedures to the saturated hydraulic conductivity allows one to obtain the effective hydraulic conductivity, which can be used to estimate the average specific discharge, the average linear velocity, and other key variables in groundwater flow. The formulas in this publication must be written in the same units International Standard or U.S. These Standards will be useful to environmental engineers, water resources engineers, and anyone who uses hydraulics in engineering.

This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book excerpt: The European DayWater project has developed a prototype of an Adaptive Decision Support System (ADSS) related to urban stormwater pollution source control. The DayWater ADSS greatly facilitates decision-making for stormwater source control, which is currently impeded by the large number of stakeholders involved and by the necessary multidisciplinary knowledge. This book presents the results of this project, providing new insights into both technical and management issues. The main objectives of its technical chapters are pollution source control modelling, risk and impact assessment, and evaluation and comparison of best management practices. It also covers management aspects, such as the analysis of the decision-making processes in stormwater source control, at a European scale, and stormwater management strategies in general. The combination of scientific-technical and socio-managerial knowledge, with the strong cooperation of numerous end-users, reflects the innovative character of this book which includes actual applications of the ADSS prototype in significant case studies. DayWater: an Adaptive Decision Support System for Urban Stormwater Management contains 26 chapters collectively prepared by DayWater scientific partners and end-users associated with this European Research and Development project. It includes: A general presentation of the DayWater Adaptive Decision Support System (ADSS) structure and operation modes A detailed description of the major components of this ADSS prototype The assessment of its components in significant case studies in France, Germany and Sweden The proceedings of the International Conference on Decision Support Systems for Integrated Urban Water Management, held in Paris on 3-4 November 2005. The book presents the ADSS prototype including a combination of freely accessible on-line databases, guidance documents, “road maps” and modelling or multi-criteria analysis tools. As demonstrated in several significant case studies the challenge for stormwater managers is to make the benefits of urban stormwater management visible to society, resulting in active co-operation of a diversity of stakeholders. Only then, will sustainable management succeed. DayWater: an Adaptive Decision Support System for Urban Stormwater Management advances this cause of sustainable urban management through Urban stormwater management, and makes achievable (by means of risk and vulnerability tools which are included) the goal of integrated urban water management (IUWM).

Book excerpt: Achieving a sustainable, reliable drinking water supply has emerged in recent years as an increasingly important goal, not only in the United States but also worldwide. This is being driven by population growth, increasing water demands, declining groundwater levels, contamination of water sources, greater awareness of adverse environmental impacts, concern regarding the potential impacts of global warming, and many other factors. Among the many methods that are being applied to achieve this goal, managed aquifer recharge is proving to be viable and cost-effective. Recent advances in the science of aquifer recharge, including the geochemistry, microbiology, and hydraulics, provide a strong foundation for the successful implementation of aquifer recharge projects. However, to achieve success, it is necessary to understand the lessons learned, taking advantage of good ideas that worked and not repeating the ideas that did not work. The overall goal of this project was to identify technical variables that result in successful design, operation, and maintenance of sustainable underground storage (SUS) facilities. The key objectives of the project were to increase the available knowledge base of SUS facilities throughout the United States, survey a variety underground storage facilities, identify and evaluate sites where SUS performance failed to meet objectives, address the use of SUS to reduce the vulnerability of water facilities, and create an easy-to-use, practical guidance document and outreach program to distribute research findings. The final report discusses surface and well recharge methods and includes a concise summary of the most important lessons learned from the 22 operating and failed recharge sites that were visited. It also includes a proposed analytical approach that may be applied for water utilities to reduce their vulnerability to service interruption and thereby enhance their system reliability. The appendix includes case studies for the 18 operating and four failed SUS facilities that were visited as part of this project. These are presented on a CD, providing useful perspectives regarding how different water utility systems have approached the need for SUS.

Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.

This book was released on 2010 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This standard guideline is the third in a series of standards that enhances the probabilistic characterization and understanding of the behavior of a key groundwater parameter, the saturated hydraulic conductivity. The geostatistical estimation and block-averaging of the saturated hydraulic conductivity find numerous applications in applied groundwater hydrology. Noteworthy are the characterization of the spatial distribution of saturated hydraulic conductivity and the specification of averaged values of saturated hydraulic conductivity over volumes of aquifer, or "blocks," for the purpose of groundwater flow model calibration. The geostatistical approach takes advantage of this spatial statistical structure, providing relatively simple results, and makes it easy to implement in the field when required conditions are met. This standard, along with ASCE/EWRI 50-08 and ASCE/EWRI 51-08, will be useful to environmental engineers, water resources engineers, and anyone who uses geostatistical methods in groundwater hydrology.
