Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...
Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...
Geotechnical Design Over Karst. It's All About the Water
Karst is a type of topography which is formed over soluble rocks, such as limestone, dolomite, or gypsum. An irregular bedrock surface is typical of most karst areas, along with sinkholes,...
A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...
Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...
Domestic-Well Water-Quality Data and Reports for the Environmental Public Health Tracking Network: USGS and CDC Collaboration
The mission of the Environmental Public Health Tracking (EPHT) Program is to provide information from a nationwide network of integrated health and environmental data that drive actions...
Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...
Optimization of Well Placement in Groundwater Long Term Monitoring Networks
Long Term Monitoring (LTM) networks play critical roles in tracking the migration of contaminants in groundwater, evaluating the efficiency of the existing remediation techniques, and...
Hurricane Protection System
This chapter discusses hurricane protection systems. Topics include standard project hurricane, levees and floodwalls, datums and elevations, and interior drainage and pump stations....
Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....
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...
Rapid Delivery
Facing nearly dry wells and a moratorium on development that was about to expire, a small town in the pacific Northwest, using the design/build delivery method, was able to quickly design...
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...
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...
Design Considerations for the North Railroad Alluvial Fan Levee System in Boulder City, Nevada
This paper presents a drainage study for a flood control levee system in Boulder City, Nevada. This levee system is located below an alluvial fan watershed and was proposed to protect...
Hydrogeology and Irrigated Agriculture
A review of drainage problems and groundwater processes on the west side of the San Joaquin Valley (SJV), California, provides useful perspectives on hydrogeology and irrigated agriculture....
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...
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...
