Sponsored by the Task Committee on the Role of Technology in Water Resources of the Water Resources Planning and Management Committee of the Environmental and Water Resources Institute of ASCE.

This report examines the impact of technology on water resource planning and management--both historically and into the future. Because technology plays a vital role in influencing sound decisions regarding water resources, this study examines it from various vantage points. Selected case studies cover a variety of settings, materials, and insights into new technological approaches.

Sponsored by the Fluids Committee of the Engineering Mechanics Division of ASCE.

This report provides environmental engineers with a comprehensive survey of recent developments in the application of fluid mechanics theories to treat environmental problems. Chapters cover principles of fluid mechanics, as well as contemporary applications to environmental problems involving river, lake, coastal, and groundwater areas.

Topics include:

• turbulent diffusion;
• mixing of a turbulent jet in crossflow -- the advected line puff;
• multi-phase plumes in...

Measurement of Oxygen Transfer in Clean Water provides the latest methods for measuring the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. This Standard (a revision of ASCE 2-91) is applicable to laboratory scale oxygenation devices with water volumes of a few gallons as well as to full-scale systems with water volumes typical of those found in the activated sludge wastewater treatment process. It is intended for use by engineers in the preparation of specifications for compliance testing and by manufacturers in the development of...

Sponsored by the Remediation Technologies for Soils and Groundwater Task Committee of the Environmental Council of the Environmental and Water Resources Institute of ASCE.

This report provides a comprehensive and thorough overview of conventional engineered processes and technologies used for the remediation of contaminated sites. Site remediation is a complex and costly process that aims to restore adversely affected land and groundwater resources to environmentally sustainable conditions.

With extensive illustrations, tables, and case studies, this book has a...

• Covers unit processes common to drinking water, wastewater, and any water requiring treatment
• Presents theory and practice for each unit process and key factors in development
• Examines uncommon issues that aid in applications principles, such as submerged flow for a Parshall flume and Henry's law constants for 12 gases at different temperatures
• Reviews how the field arrived at its present state-of-the-art technologies to shed light on current practices

Three standards are combined in one volume, intended to complement ASCE Manual of Practice No. 95, Urban Subsurface Drainage. ANSI/ASCE 12-92 provides guidelines for design of urban subsurface drainage and covers such topics as site analysis, system configuration, filters and envelopes, hydraulics and hydrology, structural considerations, and materials. ASCE 13-93 presents guidelines for installation of urban subsurface drainage and covers such subjects as site inspection, soil erosion, excavation, foundation preparation, and inspection of materials, equipment, and construction....

Prepared by the Hurricane Katrina Assessment Ports, Harbors, and Marine Team of the Coasts, Oceans, Ports, and Rivers Institute of ASCE.

This report assesses the impact of Hurricane Katrina upon coastal, port, harbor, and marine infrastructure, including levees, in the states of Louisiana, Alabama, and Mississippi. This comprehensive evaluation also offers lessons learned for the protection of existing natural coastal barriers, re-establishment of lost natural coastal barriers, and design of future coastal infrastructure to withstand storm events of Katrina's magnitude.
