Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...
Theoretical Flow Model for Drop Structures
A theoretical model based on the momentum equation is reviewed for a trapezoidal weir drop structure operating in a trapezoidal channel. Preliminary qualitative results indicate agreement...
General Design for Modifications to Existing Lower Santa Ana Drop Structures
A model study conducted at the Waterways Experiment Station investigated the possibility of utilizing the existing drop structures of the Santa Ana River. Initial tests on selected existing...
Report of Task Committee on the Collection and Publication of Basic Water Resources Data
In 1983 members of the Irrigation and Drainage Division's Committee on Surface Water expressed concern over reductions in funding for data collection and publication programs in the United...
Forty Years of Computational Hydraulics?1960-2000
The definition of computational hydraulics as used herein is: the application of numerical methods for the solution of problems of hydraulic flows, largely as practiced by the civil engineering...
Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

Liberty Restored
The Outstanding Civil Engineering Achievement of 1987 is the restoration of the Statue of Liberty in New York Harbor. The restoration work included many engineering tasks that by themselves...
Lights Out at Caribou
The Caribou powerplant restoration is one of the projects to receive an Outstanding Civil Engineering Achievement Award of Merit. On February 24, 1984 a rock slide on the ridge above the...
The Briny Deep Comes Ashore
Amusement park attractions are not all fun and games. More than 10 years of planning by dozens of firms went into the Living Seas Pavilion at Walt Disney's Epcot Center. The...
Garbage: Cogeneration's Third Dimension
Burning garbage or refuse derived fuels (RDF) is becoming more common in cogeneration plants being constructed in the U.S. The three-for-one concept turns one fuel into two products (steam...
Nuclear Waste Disposal: Where Are We?
The U.S. Department of Energy is conducting preliminary site characterizations for three candidates for nuclear waste disposal. The sites are in three different geologic sites. A Richland,...
The Scourge of Scour
Among 86 bridge failures from 1961 to 1976, more were caused by scour than by earthquakes, wind, structural problems, corrosion and accidents combined. Scour is the erosion of a stream...
Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...
Redundancy Evaluation of Existing Bridges
The redundancy of an existing bridge can only be correctly assessed by considering the full superstructure as a single entity. Any formulation based on the analysis of bridge components...
Calibration of a Bridge Rating Formula for Overload Permits
This paper proposes a method to calibrate a reliability based load and resistance factor design (LRFD) permit evaluation formulation that will account for the overloaded truck's...
LFRD Bridge Design as Viewed by the Designer
The load and resistance factor design (LFRD) design concept has been resisted by some bridge engineers on the grounds that it represents a reduction of the 'factor of safety'...
Evaluation of Corroded Steel Bridges
In the United States there is a large inventory of corroded steel bridges. The evaluation of these existing bridges is difficult when considering all the uncertainties involved in deterioration....
Multiple Presence Reduction Factors for Bridges
This paper reviews the multiple presence reduction factors specified in the AASHTO and Ontario codes, and provides a method by which these factors can be established in relation to volume...
Overview of the Guidelines for T/L Structure Loadings
This section introduces a reliability based design methodology that forms the framework for the loading guidelines. A Load and Resistance Factor Design (LRFD) format is presented for the...
