Stochastic Modeling for Drought Analysis
Periodic as well as annual stochastic streamflow models have been fitted to the highly variable flows measured at Krishnarajasagara (KRS) on river Cauvery (Southern India), which is monsoon-dependent...
Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...
Comparison of Theoretical and Historical Scour
As part of scour assessments at approximately 120 stream crossings on the New York State Thruway, subsurface investigations were performed at all structures and, in some instances, locations...
Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...
Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...
Identifying the Critical Path and Building Coalitions for Restoring Degraded Areas of the Great Lakes
Since 1985, eight Great Lakes States, the Province of Ontario, and the governments of Canada and the United States have led the development and implementation of remedial action plans...
Making the New Look Old
Between March 1990 and January 1991, Annapolis buried overhead utilities and reconstructed the roadway around the historic State House, built in 1769. The paving stones, colonial-appearing...
Archaeological Program for the Yucca Mountain Site
Archaeological surveys, limited surface collections and selected test excavations in the Yucca Mountain Project Area have revealed four distinct aboriginal hunting and gathering adaptive...
Shipwreck Management in Michigan's Great Lakes
From the year 1679, when Sier de la Salle's legendary trading ship, the Griffin set sail and disappeared on its maiden voyage, to 1975 when the Edmund Fitzgerald went down...
Beach Nourishment Episodes at the Sandy Hook Unit, Gateway National Recreation Area, New Jersey, USA: A Preliminary Comparison
A chronic erosion problem at Sandy Hook resulted in two major beach nourishment operations during the 1980's, employing material dredged from nearby navigation channels. Grain...
Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...
High Wiring Act
Prendergast describes a project to construct a 345 kV transmission line over 313 mi in southwestern New Mexico, in which, due to environmental considerations and limited access, extensive...
Infill Sampling Design for Geologic Site Characterization of Potential High-Level Radioactive Waste Repositories
Geologic site characterization is fundamental to the selection and design of a high-level radioactive waste repository. Yet, to date, the simple question 'how many samples...
Key Environmental Development Issues
Environmental statutes dealing with the control of pollutants generally regulate precriptively, establishing both technical standards, relating to discharges and their effect on the environment,...
Eutrophication and Recurrent Hypoxia in the New York Bight: A Synthesis of Historical Data and a Numerical Model of the 1976 Anoxic Event
As a result of oceanographic programs conducted over the past four decades, a large historical data base is available, and has been used, to document areas of recurrent hypoxia and high...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
Glued Laminated Timber for Bridge Construction
Structural glued laminated timber (glulam) was first introduced into the U.S. as a construction material in 1934. With the development of fully waterproof adhesives in the 1940's,...
Structural Wood Composites in Bridge Construction
Wood composites, known collectively as Structural Composite Lumber (SCL), are a family of wood-based products that better utilize the available wood fiber of a tree. This paper describes...
