Final Covers for Solid Waste Landfills and Abandoned Dumps
This book presents the essential elements for the design of final covers for solid waste landfills and abandoned dumps. Chapter 1 gives an overview and presents selected aspects of regulations...
Breaking the Chains of Codification (Available only in Structural Engineering special issue)
Structural engineers should break free of the chains placed on them by national design standards and codes that translate into totally prescriptive design. Good structural engineers perform...
Grand Gusset Failure
In May 1996, structural failure forced the closure of twin 850 ft long arched truss bridges, each carrying two lanes of interstate traffic over the Grand River, 30 mi east of Cleveland....
Journal of Geotechnical and Geoenvironmental Engineering
The Journal of Geotechnical and Geoenvironmental Engineering covers the broad area of practice known as geotechnical engineering. Papers are welcomed on topics such as foundations, retaining structures,...
Analysis
This section presents theoretical and practical concepts for the analysis of guyed transmission structures. The concepts are further illustrated in the examples of Section 8. The term...
Saving Scotland's Busiest Bridge
The world's most extensive bridge monitoring system has been installed on Glasgow's Kingston Bridge so that the engineers can prevent collapse during a long-term...
Communication Breakdown
Are modern telecommunications networks vulnerable to earthquakes? Researchers say yes, and have developed a computer tool to quantify potential economic impacts. Telecommunications service...
Intelligent Transportation Education
The comprehensive traffic surveillance study for the New York State Thruway Authority (NYSTA) began in late September 1993. The project involved the study of available traffic management...
Asphalt Update
Of the $150 million spent in the five-year Strategic Highway Research Program (SHRP), $50 million went to research to improve the durability and cost-effectiveness of asphalt pavements--on...
Historical Development of Bridge Scour Evaluations
Scour of bridge foundations (piers and abutments) is the largest single cause of bridge failures in the United States. Conversely, uncertainties of the scour depth at bridge piers and...
Influence of Backwater on Headcut Advance
A study was performed to examine the influence of backwater level downstream of an overfall on headcut advance. The discharge, overfall height, and soil type were held constant while varying...
Evaluation of Sampling Properties of General Extreme Value (GEV) Distribution-L-Moments Vs Conventional Moments
The sample estimates of conventional moments are shown to be biased and this bias increases for small samples, and especially so when the skewness is high (Wallis et al., 1974). The recently...
Three-Dimensional Numerical Model for Fish Bypass Studies
This paper describes a numerical model developed for evaluating different options for fish bypass systems at Wanapum Dam on the Columbia River, WA. The model predicts the complex patterns...
Statistical Distributions and Natural Hydrograph
For design projects in the water resources area, a hydrograph is commonly used to determine the flood volume generated by a given drainage basin. The division of total flow into direct...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
An LPI Numerical Implicit Solution for Unsteady Mixed-Flow Simulation
A Local Partial Inertia (LPI) technique is developed as an option within the National Weather Service (NWS) FLDWAV dynamic flood routing model to enhance its capability to model unsteady...
Efficient Pump Representation for Fixed-Grid MOC in Pipeline Systems
An explicit solution of the pump power failure boundary condition is shown to have many computational advantages over the conventional implicit pump boundary condition solution (i.e.,...
An Update on Surface Renewal Estimation of Evapotranspiration
The surface renewal (SR) method for estimating sensible heat flux density (H) has been shown to give good estimates of evapotranspiratiou (ET) when used in an energy balance equation with...
An Analysis of Characteristics of Basset Force on Particles Accelerating in Arbitrary Flow Field
In present study of solid-liquid two phase flow, the effect of Basset force on a particle moving unsteadily in a non-uniform flow is not very clear. For this reason, the properties of...
Arizona Local Government Bridge Scour Evaluation Study
The Federal Highway Administration has mandated that the scour susceptibility of existing bridges over waterways and open to the travelling public be evaluated. With large numbers of highway...
