Tide- and Wind-Driven Flushing of Boston Harbor, Massachusetts
The flushing of Boston Harbor, a shallow, tidally dominated embayment with little fresh water input, is investigated using a depth-averaged model. The modeled tidal currents exhibit strong...
A Predictive Model of the Currents in Cleveland Bay
A two-dimensional (depth-averaged) numerical model is proposed to describe the hydrodynamics of Cleveland Bay and is used to investigate the water circulation within the Bay. By utilizing...
Guidelines for Rehabilitation of Civil Works of Hydroelectric Plants
The
Innovative Reregulation Weirs
Since their construction, hydropower dams have generated more than just power for the Tennessee Valley Authority, they also generated concerns about their effects on river flow and aquatic...
Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...
Housing Chernobyl Relocatees
The April 1986 explosion of the Chernobyl Nuclear Power Plant Reactor 4 in northern Ukraine Commonwealth spread nuclear contamination assisted by southerly winds across hundreds of miles...
Overview of AWARE: A Software Tool for Balancing Power and Nonpower Values in Water Resource Planning
Decision Focus Incorporated has developed a software tool for the Electric Power Research Institute to help utilities and other water resource planners examine the social trade-offs between...
Reliability-Centered Management of Wood Transmission Lines
Through implementing reliability-centered management concepts, more cost-effective management of wood pole transmission lines may be achieved. By identifying individual structures and...
Probability Model of Load Exceedances under Cyclic Loadings
A probability model for nonlinear load exceedances subjected to a Poisson process with reversible cyclic load pulses was developed and is presented in this paper. A reversible cyclic load...
Earthquake Ground Motion Modeling with Stochastic Line Source
Principles of geophysics and stochastics are applied to develop an earthquake model, in which the earth medium is idealized as consisting of stratified elastic layers, responding to seismic...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Sampling Errors in U. S. Extreme Wind Records
A study of design level extreme wind speeds showed that sampling errors were the primary cause of station to station variability. A method for decreasing sampling errors in design wind...
Digital Simulation of Wind Load Effects
The time domain solution of the equations of motion of structures subjected to a stochastic wind field is often obtained by a step-by-step integration approach. The loading is often described...
Comparison of Wind Cross-Spectral Data with Models
Existing analysis procedures for the prediction of long-span bridge response to wind have until recently neglected the horizontal-vertical cross-spectral components of the wind under the...
Non-Gaussian Vortex Induced Aeroelastic Vibrations under Gaussian Wind
The 'lock in' aeroelastic vibration phenomenon observed for random wind excitation is modeled in a way that allows the application of the Slepian model process tool to obtain an approximation...
Soil/Structure Seismic Investigation of Safety-Related Structures
This paper promotes an improved understanding of the type of earthquake motions felt at V.C. Summery, Perry and Krsko nuclear power plants. An analytical investigation is performed to...
Fatigue Life Variability and Reliability Analysis of a Wind Turbine Blade
Wind turbines must withstand harsh environments that induce many stress cycles into their components. A numerical analysis package is used to illustrate the sobering variability in predicted...
Operation of the Central Valley Project During California's Drought
The Federal Central Valley Project is one of the country's major water resource developments. A severe 5-year drought has tested the capabilities of the CVP to meet its authorized purposes....
The Evolution of an Environmental Monitor
After more than 40 years of planning, litigation, design and construction, one of the nation's most controversial highway projects is finished. The completion earlier this...
Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...
