Now in an extensively updated fourth edition, this essential text offers a comprehensive survey of all aspects of water resources planning and management. Utilizing an integrated water resources management (IWRM) framework, the authors show how this approach can clarify and help resolve resource management problems in ways that take into account complicated and interconnected social, economic, and environmental needs. Spanning the full planning process, the book considers legal and administrative issues; economic and forecasting factors; water quality, quantity, supply, use and demand; and model applications. The authors’ goal throughout is to provide a practical foundation for improving ecological and human environmental systems for practitioners and students alike.
No natural resource issue has greater significance for the future of Texas than water. The state's demand for water for municipal, industrial, agricultural, and recreational uses continues to grow exponentially, while the supply from rivers, lakes, aquifers, and reservoirs is limited. To help Texans manage their water resources today and plan for future needs, one of Texas's top water experts has compiled this authoritative overview of water issues in Texas. Water in Texas covers all the major themes in water management and conservation: Living with a Limited Resource The Molecule that Moves Mountains A Texas Water Journey The Gulf Shores of Texas Who's Who in Water Texas Water Law: A Blend of Two Cultures Does Texas Have Enough Water? Planning for the Future What's in Your Water? How Much is Water Worth? Water is Our Legacy Illustrated with color photographs and maps, Water in Texas will be the essential resource for landowners, citizen activists, policymakers, and city planners.
Water utilities often do not know the specific cause of external corrosion observed on their water mains, and consequently, the chosen preventative measure may not work effectively. Historically, these choices are based on data from other industries (e.g., gas and oil) and may not be suitable for the water industry. Corrosion of metallic pipes can be caused by a variety of mechanisms, each of which requires a different solution. Determining which corrosion mechanism is at work is not a simple matter, because the resulting pipe damage looks similar for all of them. The failure to properly identify corrosion sources may produce prevention systems that are ineffective or do not last. For example, it is not effective to install an anode bag on a main that has a bacteriological corrosion problem. Similarly, an anode bag installed to reduce corrosion caused by a stray impressed current would be quickly used up and would provide only short-term protection. Much recent research on corrosion has focused on internal corrosion, primarily related to water-quality issues, such as lead and copper control and red water. This project will examine external corrosion, which affects the structural integrity of the pipe and makes it vulnerable to leaks and breakage. After identifying the causes of external corrosion, the study will find economical solutions for each type of corrosion and verify them through field trials.
Why do people fight about water rights? Who decides how much water can be used by a city or irrigator? Does the federal government get involved in state water issues? Why is water in Colorado so controversial? These questions, and others like them, are addressed in Colorado Water Law for Non-Lawyers. This concise and understandable treatment of the complex web of Colorado water laws is the first book of its kind. Legal issues related to water rights in Colorado first surfaced during the gold mining era of the 1800s and continue to be contentious today with the explosive population growth of the twenty-first century. Drawing on geography and history, the authors explore the flashpoints and water wars that have shaped Colorado's present system of water allocation and management. They also address how this system, developed in the mid-1800s, is standing up to current tests - including the drought of the past decade and the competing interests for scarce water resources - and predict how it will stand up to new demands in the future. This book will appeal to non-lawyers involved in water quality issues, students, and attorneys and water professionals desiring a succinct and readable summary of Colorado water law, as well as general readers interested in Colorado's complex water rights law.
This report summarizes research performed by the Department of Civil Engineering on water and revenue loss problems in water utilities commonly referred to as 'unaccounted-for water'. The research was conducted by the principal investigator and graduate students with assistance from Community Consultants, Inc. of Springville, Utah. The American Water Works Association Research Foundation (AWWARF) sponsored this project. The objectives of this effort are to: 1. assess the value of various methods used to measure quantities of water that are lost of not accounted for; 2. provide an appraisal of the techniques available to monitor such losses; 3. suggest standardized definitions for the terms used to describe the types and sources of water and revenue losses; and 4. identify solutions available to utilities to control such losses of water or revenue including generalized benefit/cost analysis of suggested solutions.
This Best Practice Guide on the Control of Iron and Manganese in Water Supply is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. Iron and manganese are often found in soft upland water sources associated with natural organic matter and are also commonly found in the groundwater abstracted from confined and unconfined aquifers. The presence of iron and manganese in water is one of the most frequent reasons for customers’ complaint due to aesthetic issues (yellow, brown and black or stains on laundry and plumbing fixtures). These two metals can be removed fairly readily by physico-chemical treatment. The municipal treatment systems deployed derive benefit from their larger scale, particularly in relation to control, but the processes used are less suitable for the numerous small supplies that are the most common water supplies throughout Europe, especially in rural areas. One important source of iron in drinking water is from old corroded cast-iron water mains, historically the material used most commonly in supply networks. Replacement and refurbishment is very expensive and the major challenge is how best to prioritize available expenditure. The purpose for this Best Practice Guide on the Control of Iron and Manganese in Water Supply is to give readers the broad view of a problem based on state-of-the-art compilation of the range of scientific, engineering, regulatory and operational issues concerned with the control of iron and manganese in drinking water. The Guide is of interest to water utility practitioners, health agencies and policy makers, as well as students on civil engineering and environmental engineering courses. Authors: Dr Adam Postawa, AGH University of Science and Technology, Faculty of Geology, Geophysics and Environment Protection, Krakow, Poland and Dr Colin R Hayes, University of Swansea, UK, Chair of IWA Specialist Group on Metals and Related Substances in Drinking Water.
