Cold Regions Hydrology and Hydraulics
The Cold Regions Hydrology and Hydraulics Monograph is the eighth in a series of monographs prepared by the ASCE Technical Council on Cold Regions Engineering. The book is intended to...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
Diatomaceous Soils: A New Approach
Diatomaceous soils are formed over long periods of time when the skeletal remains of plankton and other single-celled marine creatures sink and accumulate in lakes, estuaries and oceans....
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Enhancing Concrete Durability by Treatment with Sealers
This paper summarizes some of the research which has been undertaken on sealers for hardened concrete during the last ten years at Wiss, Janney, Elstner Associates. Inc. The research used...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...
Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...
Development of a Test Validated Methodology for Predicting Concrete Containment Leakage
In the past several years, considerable research effort has been devoted by the Electric Power Research Institute and the U.S. Nuclear Regulatory Commission to the behavior of reactor...
Vibration Control Damper Using Sloshing of Water
The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures....
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Accelerating Electrons
At a wastewater treatment plant in Miami, five scientists have pointed a 1.5 million v `e-beam' at pathogens and hazardous chemicals. It's the only full-scale...
Seismic Isolation of Storage Tanks
There has been a significant amount of research activity over the past decade on the seismic design of storage tanks. The seismic design issues and limit states are quite complex due to...
Seismic Large Amplitude Liquid Sloshing?Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...
Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...
Big-Scaled Tilt Test on Uplifting Behavior of Oil Storage Tanks
The authors conducted a series of static tilt tests using a very big model with the full similitude in order to investigate the uplifting behavior of large-scaled tanks. The model was...
Static Tilt Analyses of Uplifting Cylindrical Tank
This paper describes the general method adopted for predicting the static tilt performance of cylindrical liquid storage tank that is free to uplift. In the analysis described here, the...
Membranes in Water Treatment
Membrane technology, using reverse osmosis to treat drinking water, is a promising alternative to conventional treatment. The method is now being used for desalination in a growing number...
Buying Tomorrow's Water
Cities are finding that selling future access rights to sewer and water treatment plants can get them needed expansion capital. Although the access rights system is similar to development...
