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...

1852–2002: 150 Years of Civil Engineering in the United States of America
On the 150th anniversary of the founding of the American Society of Civil Engineers it is important to review the growth of the profession and the...

Surveying and Mapping: History, Current Status, and Future Projections
Since the founding of ASCE in 1852, remarkable changes have occurred in all areas of civil engineering practice, including surveying and mapping. Instruments employed in surveying and...

Wood and Wood-Based Materials: Current Status and Future of a Structural Material
Wood is one of the earliest construction materials, and the structural use of wood and wood-based materials continues to steadily increase. In fact, new wood-based materials continue to...

Mathematical Modeling of Watershed Hydrology
Mathematical modeling of watershed hydrology is employed to address a wide spectrum of environmental and water resources problems. A historical perspective of hydrologic modeling is provided,...

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,...

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...

Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...

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...

Developing a Long Term BMP Sampling Program - Initial Results from the Villanova Stormwater Urban Partnership
The Department of Civil and Environmental Engineering has teamed up with the Pennsylvania Department of Environmental Protection to create a directed studies and long term research center...

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...

The Benefits of Virtual Building Tools
Several short case studies illustrate how virtual building tools enable designers, builders, and owners to test any aspect of a project's design, organization, and schedule...

The Big Dig's Big Dig
Widely recognized as the most demanding component of Boston's Central Artery/Tunnel Project, the tunnel jacking work performed beneath operating rail tracks represents a quantum...

Under Cover
In capping a 190-acre hazardous landfill in metropolitan Los Angeles, engineers saved time and money by relying on a construction method seldom used in the environmental sector: design/build....

A Realistic Vision for the Future of IT in Civil Engineering and a Plan for Achieving It
In October 2001, a group of experts from the capital projects industry met in San Antonio, Texas to begin development of a comprehensive technology research and development (R&D)...

Rebuilding the Winter Garden
The terrorist attacks of September 11 partially destroyed the Winter Garden, a majestic public apace that connected the World Trade Center to the Hudson River waterfront on the perimeter...

Wetlands at Work
As urbanization spread to the southern portion of Staten Island—the home of New York City's last large stand of freshwater wetlands—the New York City Department of Environmental...

Building the Olivenhain
Engineers in California were hired to create a reservoir capable of providing the San Diego region with 24,000 acre-feet of water during an emergency shortage. The result is the Olivenhain...

A Retrofit for Long Lake
To reduce the effects of storm-water runoff on Long Lake, in Littleton, Massachusetts, the town is implementing a variety of low-impact solutions within the lake's highly...
