Urban Infrastructure: Our Crumbling POTW's
There is a need to address the problem of deferred maintenance at public owned treatment works. While specific data regarding the nations deferred maintenance bill is not available, we...
Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...
Analytical Hydraulic Modeling of Road Culverts
This paper summarizes the development of a comprehensive analytical methodology and a computer model capable of simulating a wide range of flow phenomena in road culverts. The new flow...
Modeling Nutrient Loadings from Croplands in the Chesapeake Bay Watershed
The Chesapeake Bay Watershed Model, based on the U.S. EPA Hydrologic Simulation Program Fortran (HSPF) provides a framework for evaluating and quantifying nutrient loadings to the Chesapeake...
BRASS Modeling of Lo?za Reservoir, Puerto Rico, for Sediment Management Operations
Loiza reservoir, the principal water supply for metropolitan San Juan, delivers 3.5 m3/s (80 mgd) to the Sergio Cuevas filter plant. Sedimentation...
Infrared Thermographic Sensing of Sewer Pipeline Problems
When a sewer caves in, it often takes the street, sidewalks, and surrounding buildings along for the ride. These collapses endanger public health and safety. Repairing a sewer before such...
Computing in Civil Engineering and Geographic Information Systems Symposium
This proceedings consists of the papers presented at the Eighth National Conference on Computing in Civil Engineering and Geographic Information Symposium, held in conjunction with A/E/C...
Site Impact Traffic Assessment
Problems and Solutions
Transportation needs have traditionally derived from land use decisions. Site impact traffic analysis is a formalized process that attempts to quantify the need for transportation improvements...
Principles of Infrared Thermography and Application for Assessment of the Deterioration of the Bridge Deck at the Zoo Interchange
This paper details the principles of infrared thermography from the underlying theoretical considerations to the physical constraints involved with performing the test. Infrared (IR) thermography...
Pavement Surface Maintenance: Overview of SHRP H-106 Experimental Installations
The Strategic Highway Research Program (SHRP) is currently conducting an experiment under SHRP project H-106 to evaluate the performance of various materials and procedures used in making...
Bridge Deck Distress and Repairs
The primary cause of bridge deck deterioration are cyclic freeze-thaw exposures and reinforcing steel corrosion caused by the extensive use of de-icing salts. However, there are other...
Regional Evaluation of Transportation Lifelines in New York State with the Aid of GIS Technology
Regional evaluation of transportation lifeline facilities which may be impacted by seismic and other natural hazards is of great concern for purposes of emergency planning and response...
Minipile Milestone in Memphis
The maintenance/administration facility for Memphis, Tennessee's 300-bus fleet began displaying structural problems before it even opened for service in 1979. The 23 acre...
Empirical Simulation of Future Hurricane Storm Histories as a Tool in Engineering and Economic Analysis
Although the database of past storm occurrences and their detailed histories and geometries at or near a site is essential to planning safe and cost-effective future engineering operations...
A Simple Method to Compute Wave Loads on a TLP
In this paper, analytic diffraction (Linton and Evans, 1990) and radiation (Kim, 1992) solutions for arrays of bottom-mounted vertical circular cylinders are used to compute hydrodynamic...
Computer Aided Design for Deep Water Offshore Risers
This paper describes a software package (OTRC-Riser-91) that was developed under the sponsorship of the Offshore Research Technology Center that is funded by the National Science Foundation...
Validation of the SEADYN90 Cable Simulation Model Using a Three-Dimensional Cable Deployment Data Set
This paper presents data from a full-scale, three-dimensional cable payout test and the corresponding numerical simulations using the SEADYN90 computer model. The experiment, which was...
Design of Tension Leg Platforms: A Knowledge Based Approach
