Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
Pressure Differences Affecting Radon Entry in New Residential Construction
Various conditions in a house can commonly produce house negative pressures up to 20 Pascals relative to the soil gas pressure. Depressurization of the house relative to the soil gas will...
Cost of Radon Control Measures in New Construction
Installation of a radon prevention system in new construction increases costs to builders and to homebuyers as well. Builders and/or their engineers will need to assess different approaches...
Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...
Flood Impact and Management of Levees in Tennessee
The construction of private levees is causing flooding and erosion problems along several tributary rivers in West Tennessee. The severity of these problems is recognized by the State...
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Design and Performance of Diversion Gates at Peace Canyon Dam
During construction of Peace Canyon Dam, river diversion was accomplished using a combination of cofferdams and temporary diversion conduits through the partially completed dam. Inlet...
Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...
Project Evaluation?Don't Miss the Boat
The hydroelectric developer is faced with many decisions during the evaluation stage. These include determining the size of the project, financial analysis to be used, type and number...
Challenging Site Conditions Lead to Unusual and Innovative Powerhouse Design Features
Pacific Gas & Electric Company's recently completed Newcastle Powerhouse is located on the shore of Folsom Lake near Auburn, California. The $26 million facility uses...
Uplift under Concrete Dams on Rock
While the possible existence of uplift pressures within dams and foundations is no longer questioned, there is still considerable controversy over the magnitude and distribution of uplift...
Uplift Pressures in Existing Concrete Dams
This paper is a brief summary of a report of the same title prepared for the Electric Power Research Institute (EPRI) as part of its program to study ways to economically improve dam safety....
Uplift Pressure below Gravity Dams on Rock
The magnitude of the uplift force at the base of a concrete gravity dam founded on rock is strongly dependent on the properties of the discontinuities within the rock mass. This paper...
Effect of Seepage in Cracks in Older Gravity Dams
One of the many problems encountered by dam designers is that of estimating uplift pressures in cracks within older concrete dams. As part of ongoing research, we are investigating this...
