Water Treatment Plant Design
Let a team of water treatment plant design experts . with contributions from more than 30 international authorities -- give you comprehensive guidance on modernizing existing water treatment...

Analysis
This chapter presents a brief overview of the current analytical modeling techniques for isolated structures. Perhaps the biggest challenge in the design of an isolated structure is incorporating...

Fundamentals of Seismic Isolation
This chapter examines fundamentals of seismic isolation, including its principles, history, and examples of seismically-isolated structures....

Evaluating Seepage Losses and Liner Performance at Animal Waste Lagoons using Water Balance Methods
This chapter discusses techniques for evaluating seepage losses from existing animal waste lagoons under field conditions....

Optimal Selection of Rechlorinization Station in Water Distribution System by Optimization Techniques
The optimal rechlorination in water distribution systems was investigated by incorporating optimization techniques into a numerical water quality model (EPANET2). Four types of optimization...

Estimating the Return Period of Multiyear Droughts
Characterizing the return period of hydrologic events has been an important subject in water resources planning and management studies for many decades. The alternative approach has been...

Integrated Water Management for the 21st Century: Problems and Solutions
Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses...

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

Review of Stabilization of Clays and Expansive Soils in Pavements and Lightly Loaded Structures—History, Practice, and Future
Expansive clay soils—those that change significantly in volume with changes in water content—are the cause of distortions to structures that cost taxpayers several billion dollars annually...

Unleashing the Flow
A 70-year-old, two-lane roadway that stretches from Miami to Tamp Bay is impeding the flow of water through the Everglades. By studying eight possible solutions in detail, engineers determined...

Assessing Long-Term Pollutant Concentration Trends in Urban Runoff for TMDL Planning and Regulatory Assessment
Loads of some pollutants in many urban watersheds include a substantial component originating with non-point sources and stormwater runoff. TMDL planning includes estimating those loads,...

Assessment of Water Quality Monitoring Sites by an Optimization Method
Allocation of sampling sites is the initial and the most crucial step of the water quality monitoring network design and redesign process. Several different approaches have been used within...

Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...

Rate of Under-Registration Due to Failures of Large Meters
Leaks and meter under registrations are suspected as primary components of unaccounted-for water in Korea. In 2001, national unaccounted-for-water rate is reported as 26.6%. More than...

Overall EWRI/ASCE Standards Process
The American Society of Civil Engineers is an ANSI-accredited standards development organization (SDO) and as such develops consensus-based standards in a wide-range of technical areas...

Characterization of Anaerobic Microbial Consortium Response to Thiol-Reactive Compounds
The activity of anaerobes in wastewater treatment processes can be limited when a toxicant enters the system. For certain toxicants, along with the decrease in metabolic activity, an efflux...

Replacing a Dying Water Infrastructure
The water infrastructure in the United States will soon need massive repairs. Pipes are leaking, and most pipes are near the end of their life cycles. Tens of thousands of sewer overflows...

Development and Application of a Decision Support System for Municipal Water Infrastructure Planning: Challenges and Successes
Many water utilities across the country continue to face the challenge of intelligent planning for cost effective, efficient operation, larger demands, stricter government regulations,...

The Pocono Creek Goals-Based Watershed Management Pilot Study-Phase 2
Phase 2 of the Pocono Creek Pilot Study begins with focusing on the issues identified in Phase 1 and prioritizing them on a watershed wide scale. The Pocono Project worked through the...
