Measuring Highway Inventory Features Using Stereoscopic Imaging System
The new stereoscopic measurement approach is discussed in this paper. The objective of this paper is not intended to present another new videologging system. Instead, this paper is to...

Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...

Flexible Pavement Distress Evaluation Using Image Analysis
A unique combination of image histogram and projection histogram are employed to classify major distress types on flexible pavement. This technique has taken into account the presence...

Reef Breakwater Design for Lake Michigan Marina
An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The...

The Application of a Structural Analysis Program to Floating Dock and Guide Pile Design
The floating dock systems and guide piles used in marinas are often designed using over simplified analysis techniques. However, if the dock system is flexible or if either the soil conditions...

Design Experience Gained Through Physical Modeling of Small-Craft Harbors
A research work unit has been initiated to determine the state-of-knowledge of small boat harbor design. Existing design criteria for small-craft harbor design is based primarily on 'rule-of-thumb'...

Physical Model Testing of Barbers Point Harbor and Marina Complex
A three-dimensional, physical model study of the Barbers Point, Hawaii harbor and marina complex is being conducted at the US Army Engineer Waterways Experiment Station, Coastal Engineering...

Simplified Tidal-Flushing Model for Small Marinas
This paper describes the development and application of a new water quality screening model - STEAM (Simplified Tidal Embayment Assessment Model). This model simulates the first-order...

Predictive Techniques for Marina Water Quality Assessment
The construction of new marinas in coastal areas requires as assessment of potential impacts on water quality as a part of the permit process. This paper summarizes a study sponsored by...

Application of a Numerical Model to Develop Marina Concepts
A numerical model is presented to evaluate wave conditions in a marina basin for development and analysis of marina concepts. This model is based on the boundary integral equation method...

A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...

Avalon Harbor Utilization
Avalon Harbor is a destination resort harbor which serves the Southern California boating community and recreation public. The harbor is a roadstead mooring in a partially protected cove....

Influence of Rigidity of Soil Surrounding Shield Tunnel Upon Equivalent Rigidity of the Tunnel in Axial Direction
The purpose of this study is to investigate the interaction between ground surrounding a shield-driven tunnel and segments, especially their ring-joint portion. When a seismic force acts...

Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...

Pavement Design by Elastic Layer Theory
The U. S. Army Engineer Waterways Experiment Station has been developing methodology by which airport/airfield pavements can be designed based on elastic layered analysis for the Federal...

DFW Pavement Management System Implementation
Dallas/Fort Worth International Airport is implementing a comprehensive pavement management program to assist them in identifying and prioritizing maintenance, rehabilitation and reconstruction...

Geotechnical Engineering Congress?1991
This proceedings, Geotechnical Engineering Congress 1991, consists of papers presented at the Geotechnical Congress held in Boulder, Colorado...

Air-Water Mass Transfer
This monograph, Air-Water Mass Transfer: Selected Papers from the Second International Symposium on Gas Transfer at Water Surfaces, consists of papers presented at the Symposium which...

Reliability of Overhead Transmission Lines Subjected to Wind Action
The probability distribution of the strength of steel towers used in transmission lines, due to wind excitation, is evaluated on the basis of test results of 72 towers of various designs,...

Fully Nonlienar Models to Simulate Structural Response to Wind Loading
