The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...
Cross-Shore Sediment Transport Determined by EOF Method
Laboratory and field data of beach profile changes are used to study the cross-shore transport rate. The Empirical Orthogonal Eigenfunction analysis is applied to separate the temporal...
Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...
Implementation of Vertical Landfill Expansion
Montgomery County, Maryland, proposed to implement a vertical expansion or 'piggyback' design for the County's municipal solid waste landfill. The...
Remedial Planning for the Former EXPO 86 Site
This paper describes the site characterization and remedial action planning effort that is being undertaken at the former EXPO 86 site in downtown Vancouver, B.C. The 200 acre site on...
Reliability-Based Estimates of Wetland Detention Times for Wastewater Treatment
Determination of the hydraulic residence or detention time is often the first step in design of wetlands constructed for wastewater treatment. Current methods for estimating wetland detention...
Composite Liner, Leak Detection System, and Floating Cover for Nuclear Reactor Emergency Retention Basins
Existing reactor effluent basins are being retrofitted with composite liners, leak detection system and floating covers. Such basins have a 15-year life and remain empty until an accident...
Influence of Hydrodynamics on Biofilm Accumulation
The influence of hydrodynamics on biofilm thickness was investigated under laminar and turbulent flow conditions. The maximum biofilm thickness was found within the transition region between...

Breaking Down the Barriers
The structural engineering of multistory buildings is a complex and time-consuming chore, but new design and analysis tools can greatly simplify the task. The article traces the development...
CADD for Export
By using sophisticated structural design software and high-speed PCs, engineers in Pittsburgh overcame myriad problems when designing a highrise industrial tower in India. First, they...
The Impact of Drought on Hydropower Generation-Case Study of Bureau of Reclamation Hydropower Plant
The paper explores the effects of extended drought on power generation at Shasta hydropower plant, a Bureau of Reclamation facility in Northern California. Statistical measures of water...
Small and Low Head Pumped Storage Projects
With the recent completion of several very large pumped storage projects, the perception of a hydroelectric pumped storage project in some power industry circles may be that of a project...
Benefits and Applications of Modular Hydroelectric Pumped Storage
Hydroelectric pumped storage is the only proven and most efficient technology available for energy storage. It is used by utilities to provide peak and intermediate power and to optimize...
Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...
Lake Siskiyou Power Project
The Lake Siskiyou Power Project was constructed at the foot of the existing Box Canyon Dam on the Sacramento River in Northern California. Major project features included the construction...
Net and Hydroacoustic Monitoring of Fish Passage
In 1986 EPRI published a review of available fish protection technologies for use at hydroelectric facilities. One major conclusion of that study was that fish protection systems were...
Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
