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...
Applicability of Gabion Dams for the Control and Release of Storm Water Runoff
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,...
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...
Water Leakage through Cracks in Reinforced Concrete
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...
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...
Hydrologic Assessment for Riparian Restoration Projects
Sediment Rating Curves Based on Ranked Values
Loop Rating Curves from Goodwin Creek
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...
Rate-Dependent Plasticity Representation for Energy-Absorbing Materials
A three dimensional rate-dependent plasticity constitutive model is developed for rigid polyurethane foams. In the model, the material is decomposed into skeleton and solid matrix from...
Constitutive Modeling and Simulation of Energy Absorbing Polyurethane Foam Under Impact Loading
The compressive-stress strain response of polyurethane foam under uniaxial compressive impact loading has been studied. The development of a uniaxial constitutive model from strain rate...
Comparative Evaluation of Plasticity Theories Against Tension-Torsion Test at Finite Strain
This paper investigates and evaluates three hardening theories against a variety of nonproportional loading experiments on tubes made of annealed copper. It was concluded that the isotropic...
