Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...
Project Priority Ranking Under CWPPRA
This paper presents an economic analysis of the procedure of ranking wetlands projects under the Coastal Wetlands Planning Protection and Restoration Act (CWPPRA) as implemented in Louisiana....
Recent Bentthic Foraminifera as a Sedimentation Tool in the Nigerian Coastal Environment
The ratio between the living and total populations of benthic foraminifera has been shown to be useful in determining relative rates of sedimentation in paralic and marine environments....
Aeolian Sediment Transport Under Offshore Wind Conditions: Implications for Aeolian Sediment Budget Calculations
Field studies of aeolian sediment transport on natural beaches reveal measured transport rates that are lower than those predicted by existing equations developed in arid environments...
The Use of a Flood Damage Rating System to Aid Urban Stormwater Management
Increasing urbanisation and the subsequent decrease in natural storage and infiltration potential in a catchment, cause increased runoff peaks and volumes. Existing stormwater drainage...
CPIVOT v 2.0 Center Pivot Analysis and Design Software
A micro-computer based software package is presented which can be used for hydraulic design and/or analysis of center pivot irrigation systems. The software is written in C and requires...
Availability Analysis of Irrigation Systems for Improved Management
Availability of an irrigation system is defined as the ratio of time of successful system operation to total desired operation time. Operation is successful when the flow rate of water...
New Jersey Bridge Scour Evaluation Program
The New Jersey Department of Transportation has undertaken an ambitious scour evaluation program for the existing waterway bridges in the state. The methodology developed and utilized...
Selecting Sediment Transport Equation for Scour Simulation at Bridge Crossing
Gravel transport formulas were tested in order to select a formula for simulating stream channel changes of Stony Creek in northern California. At a stream reach undergoing scour, the...
Reliability Analysis of Levee System of a River
The levee height is determined by the summation between computed water level and an assumed freeboard. The water level is computed by given discharge in the steady conditions. Therefore,...
The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...
Gas Pipeline Fitness-for-Service Investigation
A delta reclamation district's plan to add significant fill on their levee caused great concern for the integrity of a critical PG&E 22-inch (559 mm) gas transmission line which...
Level of Service in Bridge Management Systems
The Federal Highway Administration's Sufficiency Rating is not adequate for evaluating bridges. It ignores fundamental bridge characteristics and is far too subjective. The Level of Service...
Radiographic Visualization in Experimental Soil Mechanics
A summary of the principles of such methods is presented, i.e. stereophotogrammetry, infrared thermography and radiography and their respective ranges of applicability are discussed. Then,...
A Novel Approach to Develop a Performance Based Test for Rutting of Asphalt Concrete
Asphalt concrete consists of compacted granular aggregates mixed with viscoelastic asphalt cement. The predictive phenomenological models had limited success in explaining the origin and...
Evaluation of Runway Roughness for Fighter Jets
A new roughness evaluation procedure is needed, especially, when dealing with modern fighter jets. To this end, a comprehensive pilot attitude survey was conducted in Israel in order to...
In Search of Better Load Ratings
Typically, engineers must make a number of subjective assumptions regarding loading and response behavior when they develop a load rating for civil structures. As a result, many unknowns...
Load Testing of Permanently Cased Drilled Shafts Founded in Hartford Shale
The axial and lateral load testing of three, 30 inch (76cm) diameter, permanently cased drilled shafts is analyzed herein. The prototype shafts were founded in (or on) Hartford Shale bedrock,...
Foreign Investment in Latin America: A Second Look
It has become common to hear that Latin America has emerged from the lost decade of the 1980s, a period when virtually every country in the region suffered from high debt, high inflation...
Longshore Sediment Transport Rate at Morro Bay, CA
Estimates of sediment transport rate in the vicinity of Morro Bay Harbor are needed as part of an investigation of possible modifications to the existing Federal project. Because the site...
