Waste Geotechnics and Geosynthetics
The geotechnology related to waste management focuses around assessing the movement of water and pollutant transport, containment of the pollutant so that it is unable to pollute the underground...
Rate Effects in the Deformation of Rocks
This paper gives a brief review of creep and rate effects on the behavior of rocks, within a wide range of confining pressures and temperatures, and with a special emphasis on the physical...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Practical Prediction of Concrete Shrinkage and its Uncertainty
An improved prediction model for shrinkage is proposed. The main features are (1) diffusion-type size dependence for humidity effects, (2) initial and final asymptotic forms of the shrinkage...
Early-Time Strength and Elastic Modulus of Concrete With High Proportions of Fly Ash
Compressive strength and elastic modulus data are presented for four concrete mixtures with ratios (by volume) of Class C fly ash to total cementitious materials (portland cement plus...
Parameter Study of Stresses in Mass Concrete Using Two Fly Ash Mixtures
Finite-element modeling of the incremental construction procedure for mass concrete structures has been used to study the effects of three mechanical properties on thermal stresses. Material...
Irrigation and Drainage
This proceedings consists of 70 papers presented at the National Conference on Irrigation and Drainage sponsored by the Irrigation and Drainage Division of the American Society of Civil...
Site Assessments
The 1986 Superfund Amendment and Reauthorization Act (SARA) established an innocent purchaser defense applicable if a new owner conducts appropriate inspection and appropriate inquiry...
Let the Buyer Beware
As recently as the 1970s, state highway agencies blindly purchased land for projects without much concern for hazardous waste. But that changed in 1980 with Superfund legislation, specifically...
No Feet of Clay
The methods of dealing with hazardous waste are evolving. At Superfund sites, for instance, excavation and removal was once the popular choice for treating pollutants, but stabilization...
Recharging Ground Water
For more than 55 years, the Orange County Water District has been responsible for the protection and management of the extensive ground water basin which lies under Orange County, California....
Ocean Energy Recovery
This proceeding of the International Conference on Ocean Energy Recovery held in Honolulu, Hawaii from November 28-30, 1989 consists of thirty-eight papers. These papers explore various...
Cleaning Up: The Second Decade
Endless media coverage and a high level of public anxiety make it seem as though the U.S. has been attempting to clean toxic waste sites for decades. In fact, the 1980s were our first...
Great Lakes Waters: Too Little or Too Much?
Water supplies in the Great Lakes Basin, the world's largest fresh water supply, are more than adequate to meet current and projected needs. However, supplies could become...
The Impact of Agricultural and Industrial Development on the Water Quality in Latin America and the Caribbean
Agricultural and Industrial development are having a serious negative impact upon the quality of water resources in Latin America and the Caribbean. The continuing demographic explosion...
Extent and Sources of Ground Water Contamination Now in the Nineties
In spite of man's tendency toward grandiose surface-water projects which resist natural forces, along with a political climate which spawns disincentives to conserve and economically...
Ground-Water Management and Aquifer Protection Plan
Just because a water quality problem is not known to exist at the present time does not mean that one may not appear tomorrow or at some other time in the future. Contingency plans should...
Treatment of Contaminated Groundwater
Treatment of groundwater contaminated by improper disposal practices of the past, routine agricultural chemical usage, accidents, and leaks is going to be of increasing importance. Prevention...
Governments' Role Relative to Public and Political Pressures
Groundwater quality is a major concern in the United States today. The body of law pertaining to the protection of groundwater quality is generally inadequate for the implementation of...
Regulatory Perspective on Ground Water Pollution Cleanup in the Santa Clara Valley
The Santa Clara Valley is located at the southern end of San Francisco Bay and serves as the home of approximately 1.2 million people. Approximately 40% of the Valley's water...
