Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...

Water Quality Aspects of Irrigation and Drainage: Past History and Future Challenges for Civil Engineers
This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discussed legislation and policies that affect irrigation and drainage...

Storm-Water Strategy
Water pollution laws are certainly nothing new, but increased public scrutiny, beach closures, and media coverage—particularly in Orange County, California—have placed new pressures on...

Hazard and Resource Considerations in Site Development in Virginia Karst

Ground Improvement in Zárate

Redesigning the San Roque Dam
Engineers updated a 20-year-old design for the San Roque Dam in the Philippines to save time and money and improve the dam's ability to withstand earthquakes. The structure...

Piece by Piece
The Lions' Gate Suspension Bridge, a landmark structure in Vancouver, British Columbia, marks the entrance to one of the busiest harbors on the west coast of North America....

Draining in a New Direction
(Available on in special edition) Wick drains can stabilize slopes and landslides by accelerating soil consolidation and settlement. But conventional wick drains, driven vertically into...

Exploring All Options
To relieve environmental stress around the Tampa Bay area's existing groundwater wells, Tampa Bay Water—the regional water supplier—is implementing a Master Water Plan that...

Replacement Strategy
Water Works II, a $275-million water treatment plant currently under construction in Detroit, is redefining the way that such projects are let and built. In 1980 the city initiated a program...

Coming to the Surface
In the past few years, the coastal areas of the Gulf of Mexico and much of Texas have experienced less than normal rainfall and record water demands. During this period, average daily...

Water Quality Restoration of the Mammoth Cave Karst Aquifer: A Work in Progress
Over tens of thousands of years the aquatic ecosystem of the Mammoth Cave Karst Aquifer evolved in concordance with natural recharge supplied through 24,000 hectares of tall-grass prairie...

Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...

National Water Quality Assessment: Moving from Measurement to Understanding
The USGS National Water Quality Assessment (NAWQA) program began in 1991. The objectives of the program were to characterize the quality of the Nations ground and surface water, assess...

Probabilistic Simplified and Detailed Subsurface Drainage Water Quality Modeling of Nitrate Leaching
A transparent uncertainty structure is derived for simplified and detailed conceptual nitrate leaching as a result of a probabilistic modelling procedure. The uncertainty structure consists...

Rediscovering the Lost City
Since 1994, Kenneth R. Wright, P.E., of Wright Water Engineers, in Denver, has been studying evidence of civil engineering at the ruins of Machu Picchu—an ancient Inca city in the Andes...
