Complete, practical coverage of pollution control regulations and water quality modeling

Water Quality Modeling for Wasteload Allocations and TMDLs provides practical guidance for engineers charged with determining the volume and character of wastewater that a body of water can receive without suffering environmental damage. Following the discussion on water pollution control regulations and their relationships to water quality modeling and wasteload allocation for determining the total maximum daily load (TMDL), the first half of the book focuses on quantifying the model coefficients to characterize physical, chemical, and biological processes of a variety of water quality problems.

The remainder of the book guides engineers in the application of EPA-developed models for regulatory use. Presenting numerous case studies and a substantial amount of data, this comprehensive guide:

• Covers practical applications of wasteload allocation
• Provides guidance to develop technical information for obtaining National Pollution Discharge Elimination System (NPDES) permits
• Demonstrates the application of STREAM, QUAL2E, WASP, and HAR03

Water Quality Modeling for Wasteload Allocations and TMDLs is an essential resource for state and federal water quality agencies, consulting engineering firms, publicly owned treatment works, environmental biologists and chemists, and public health officials involved with pollution control.

Water is a precious resource essential for all forms of life, and although there is plenty of water to meet the demand for the present population - and even for a projected population of 9 billion - there is significant spatial and temporal variation in its distribution. This results in water rich and water poor countries, water-related conflicts, and unsafe drinking water, a major killer identified by the World Health Organization (WHO). Water for Life: Drinking Water, Health, Food, Energy Nexus covers these issues, highlighting the multi-facted uses and importance of water in life: water resources, chemistry of water, drinking water, and the links between water and health, food, irrigation, soil, energy, transport, industry, recreation, disasters, and conflicts. The book is accessible and clear, with technical elements. It is ideal as a background supplementary text to support more specialist study across civil engineering, geography, and social sciences, and will guide readers to see the big picture of environmentally sustainable water management for all human and other biotic lives.

This second edition of Fundamentals of Open Channel Flow focuses on theory followed by clear, fully-solved examples, and practical computational tools such as spreadsheets and industry standard software. It builds on a foundation in fluid mechanics and offers the basics of a first course in open channel flow for senior undergraduates or graduate students: energy, momentum, friction, and gradually varied flow, both qualitative and quantitative. This edition provides more coverage of design applications, including culvert design, a wider range of channel shapes, and an update of the US Corps of Engineers' HEC-RAS program. It shows how a few simple equations can solve a range of basic problems. The energy-depth and momentum-depth relationships are examined graphically and the book's website offers unique animations showing actual flow dynamics of some transient flow problems, as well as solutions to end-of-chapter problems and PowerPoint slides for instructors.

Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers.

Ever since the publication in 1997 the original Scour Manual has helped many practising hydraulic engineers to deal with scour processes near hydraulic structures. In recent years new insights, such as probabilistic calculations, offered new opportunities to design structures more economically. These new insights are included in this update of the original Scour Manual, which is focussing entirely on current-related scour. This manual provides the engineer with useful practical methods to calculate the dimensions of scour holes in the pre-feasibility and preliminary stages of a project, and gives an introduction to the most relevant literature. This updated Scour Manual contains guidelines that can be used to solve problems related to scour in engineering practice and also reflects the main results of all research projects in the Netherlands in recent decades. The so-called Breusers equilibrium method has a central role, which can basically be applied to all situations where local scour is expected. The method allows to predict the scour depth as a function of time, provided that the available knowledge about scour at the specific structure is sufficient. For structures with insufficient knowledge available, alternative scour prediction rules are presented. The treatment of local scour is classified according to the different types of structures. Each type of structure is necessarily schematised to a simple, basic layout. The main parameters of a structure and the main parts of the flow pattern near a structure are described briefly insofar they are relevant to the description of scour phenomena. New scour formulas for the equilibrium scour have been elucidated. Evaluating a balance of forces for a control volume, it is possible to develop scour equations for different types of flow fields and structures, i.e. jets, abutments and bridge piers. As many scour problems are still not fully understood, attention is paid to the validity ranges and limitations of the formulas, as well as to the accuracy of the scour predictions. This information can also be used to carry out a risk assessment using a safety philosophy based on a probabilistic analysis or an approach with a safety factor. Moreover, the information on the strength of soils is extended and aspects are addressed such as scour due to shear failures or flow slides, that can progressively damage the bed protection which might lead to the failure of hydraulic structures. This updated Scour Manual presents scour prediction methods and deals with practically related scour problems. Consultants and contractors were invited to provide case studies of realized projects, including the methods that were followed. These case studies will help with grasping the concept of scour by the flow of water. This manual provides the engineer with the latest knowledge and with case studies that show how to apply the formulas and their limitations.

This new book explains advanced and emerging technologies for removing heavy metals from wastestreams and contaminated sites.

This book explores how conflicts around access to water shape cities, citizenship and infrastructures by tracing how water is commodified and controlled by the Public Enterprises of Medellin (EPM), one of the most successful publicly owned utility companies in the global South. Why are water inequalities dramatically increasing in Medellin, a city that is located in an area of bountiful water resources and owns a successful, established utility company? This book explains this paradoxical situation by weaving together two central threads. The first is a critical historical analysis of the political, economic and ecological conditions that enabled the city's utility company to grow and expand internationally, and the second is a rich account of the everyday practices and struggles of residents in low-income areas to secure access to water and demand citizenship rights. The EPM is a case of global significance as the company continues to expand its commercial operations in the Latin American services market by taking over the utilities in Panama, El Salvador and Guatemala, Mexico and Chile. Although its successful international expansion has been a source of pride and admiration for many Colombians, the implementation of market-oriented operating principles in all activities of the utility company raises important and complex questions about its public character and responsibility in the provision of basic services, which has much wider implications given how it is poised to be a model for other for-profit municipal service operations in other Latin American countries. This book advances the empirical knowledge of corporatized utilities, with a globally significant case, as well as providing new theoretical insights with which to understand the limits, challenges and opportunities faced by public utility companies to provide affordable and equal access to water in cities. This book will be of great interest to students and scholars of water resource management, corporatization, privatisation and commodification of natural resources, urban studies, citizenship and human rights, environmental sociology and Latin American studies.

This book examines water remunicipalization in Cochabamba since the Water War, offering innovative methodological and theoretical conceptualizations of what it means to be "public," helping to move debates on water services beyond the paralyzing binary of public versus private with a focus on the contested terrain of community engagement around water services. The Cochabamba Water War of 2000 brought together city residents of all stripes to mobilize against water privatization and gain back public control of the city's water utility. This event catapulted anti-privatization movements around the world, but two decades later, the water movement's vision of democratic water provision remains largely unfulfilled and the city suffers from a protracted water crisis. Building a typology of participation, this book explores the difficulty in rebuilding a strong public water service in Cochabamba by analyzing the different, and often incompatible, understandings and interpretations of social control and public participation. Applying this framework to the Bolivian context, and more specifically to the water and sanitation sector in Cochabamba, the book uncovers whose interests are served, and which groups are included or excluded from decision-making and access to water. This exercise illustrates how, in their implementation, participatory practices are not linear and can be distorted or appropriated towards different ends. This book will be of great interest to students and scholars of water governance, natural resource management, public policy, social movements and Latin American studies.
