Annotation Twenty-four contributions address the history of various government and academic organizations that have played a role in the nation's water resources and environmental activities. Papers address topics including environmental engineering history and developments, hydraulic engineering pioneers, Bureau of Reclamation history and developments, university water and hydraulic education and research, hydrology and water resource planning, and an invited paper discussing the history of life on the Coosa, Tallapoosa, Cahaba, and Alabama rivers. Six contributions discuss the formation of the Environmental and Water Resources Institute (EWRI) and the history of ASCE technical divisions and codes and standards activities.

This Task Committee report provides standardized equations for calculating reference evapotranspiration (ET) from weather data and procedures for quality assessment and control of weather data. The purpose of the standardized reference ET equation and calculation procedures is to bring commonality to the calculation of reference ET and to provide a standardized basis for determining or transferring crop coefficients for agriculture and landscape use. The basis of the standardized reference ET equation is the ASCE Penman-Monteith (ASCE-PM) method Manual 70. Along with applications for the ASCE-PM method, this report includes recommended calculations for vapor pressure, net radiation and wind speed adjustment, and guidelines on assessing weather data integrity and estimating values for missing data. The development of this standardized report by the Environmental and Water Resources Committee (EWRI) of ASCE, was made at the request of, and has been endorsed by, the Irrigation Association.
MOP 110 presents extensive advances in methods of investigation, measurement, and analysis in the specialized field of sedimentation engineering.
This guide examines permanent structural techniques, or Best Management Practices (BMPs), which can be used for retrofitting the stormwater management systems in existing developed areas. The advantages and disadvantages of each technique are explained to help engineering professionals select the BMP (or series of BMPs) best suited for removing pollutants from stormwater runoff at a particular location. The design factors considered include land availability, type of pollutant to be removed, groundwater levels, soil types, BMP costs, maintenance costs, and desired pollutant removal efficiency. The BMPs evaluated are ponds, alum treatment systems, constructed wetlands, sand filters, baffle bo...
Prepared by the Task Committee on the Development of Prestandards for Concentrate Management Case Studies of the Desalination and Water Reuse Technical Committee of the Water, Wastewater, and Stormwater Council of the Environmental and Water Resources Institute of ASCE.Concentrate Management in Desalination: Case Studies, Second Edition, reviews the state-of-the-practice for managing concentrate streams resulting from desalination processes.Concentrate management and disposal in desalination pose environmental and cost concerns--and often determine whether a desalination project is viable, especially for inland communities. This book examines many facets of concentrate management in desalina...
This volume investigates the origin, development, role, application, and current status of the curve number method for estimating the runoff response from rainstorms.
Louisiana's coastal wetlands represent a significant natural and economic resource for the state and the nation but have been disappearing at a rate of 25 to 35 square miles each year. In the past 50 years, more than 1,500 square miles have been lost. The wetlands contain 95% of all marine species in the Gulf of Mexico, 30% of the nation's fisheries, and one of the largest habitats in the world for migratory waterfowl. More than 25% of all oil and gas used in the United States originates or passes through these wetlands, which also serve as a buffer for hurricanes. The State of Louisiana asked ASCE to convene a summit to discuss technical aspects involved in carrying out restoration programs and to report on the insights that could be drawn from the summit. This report provides conclusions and recommendations concerning the technical topics discussed at the summit as well as the Task Committee's recommendations for a path forward.
Sustainable Water Resources Management presents the most current thinking on the environmental, social, and political dimensions of sustainably managing the water supply at local, regional, or basin levels.
Sponsored by the Task Committee for the Shared Use of Transboundary Water Resources of the Environmental and Water Resources Institute and the Laws and Institutions Committee of ASCE. This report proposes clear standards and principles for effective and efficient water sharing among two or more autonomous political bodies. Drawing from existing transboundary agreements, this report presents a series of model codes that could limit the potential for conflict while providing an appropriate balance among efficient use of the water resource for economic purposes, public health, and ecological protection. Three model agreements are presented for use according to the willingness of the parties to forgo sovereignty. All three models?coordination and cooperation, limited purpose, and comprehensive management?focus on the allocation and use of shared waters and on resolving conflicts involving such waters. These three water sharing agreements can be used within the United States and, with minor alterations, in the international arena.
