Effects of Hydroelectric Turbine Passage on Fish Early Life Stages
Turbine-passage mortality has been studied extensively for juveniles and adults of migratory fish species, but few studies have directly quantified mortality of fish eggs and larvae. An...
Estimation of Loading via Fingered Flow
Results of experimental investigations of fingered preferential flow are combined into a concise, conservative engineering methodology for predicting pollutant transport through fingered...
Wind Generated Wave Resuspension of Sediment in Old Tampa Bay, Florida
Vertical profiles of velocity and suspended-solids concentration were measured at a scientific instrumentation platform in Old Tampa Bay during the passage of a cold front in March 1990....
Preventing Stilling Basin Abrasion
A 1:10 scale physical hydraulic model of Taylor Draw Dam outlet works was used to develop modifications to prevent back flow intake of rock into the stilling basin. Much of the back flow...
Partnering Benefits?A Headquarters Department of the Army Perspective
Army facilities make a statement by reinforcing and reflecting Army values. High quality facilities attract, motivate, and retain quality personnel vital to national defense. As defense...
The Enhancement of Air-Sea Gas Exchange by Oceanic Whitecapping
The hypothesis that oceanic whitecaps and the accompanying buoyant bubble plumes greatly enhance the air-sea transfer coefficient of gases subject to liquid phase control has recently...
Parameterization of Air-Ocean Gas Transfer
A renewal-type model, based on the physics of a molecular sublayer, allows the derivation of parameters to describe air-ocean gas transfer and the temperature difference across the cold...
Guide to the Use of the Wind Load Provisions of ASCE 7-88 (formerly ANSI A58.1)
The objective of the
Probabilistic Assessment of Wind Loading For Structural Analysis
Records of extreme annual gust velocities from 11 weather stations in central-southern Brazil, classified according to orientation (octants) and type of storm (TS and EPS winds), result...
Wind-Induced Response of Torsionally Coupled Buildings
This paper summarizes the results of a comprehensive three-dimensional dynamic analysis of tall buildings subjected to fluctuating wind forces. Random vibration theory is used to relate...
Reliability Analysis in Estimating Turbulent Wind Force on Offshore Structures
This paper presents the results of a reliability analysis carried out to estimate low frequency turbulent wind drag force (including extreme values) acting on a floating offshore structure....
Loading Uncertainties in Extreme Waves
Uncertainties associated with extreme base shear forces and extreme overturning moments are estimated for an idealized eight-legged jacket platform. The structure is assumed to respond...
Stochastic Evaluation of Landing Pier Construction
This paper discusses the process of determining the magnitude of external force such as wind and wave pressure exerted on marine structures under construction, and the learning curve of...
An Investigation of Live Loads on Concrete Structures During Construction
Slab formwork live loads include the weight of equipment, construction material storage loads, and impact loads when placing the concrete. In this paper material and equipment loads are...
Local Economic Impact Assessment of the Nevada Test Site: A Methodological Prelude to Socioeconomic Assessment of the Proposed Yucca Mountain High-Level Radioactive Waste Repository
The economic impact of the high level of nuclear repository can be approximated by studying the economic effects of the Nevada Test Site. Using the UNLV Nevada models, we estimated the...
Accident Analyses in Fulfillment of the Requirements of the National Environmental Policy Act and Their Relationship to the Packaging and Testing Requirements of the Nuclear Regulatory Commission
In planning its Transportation Program, the Office of Civilian Radioactive Waste Management must address two fundamental questions: (1) To what extent are the reasonably foreseeable significant...
Space Debris?A Design Consideration
With the increased use of space by manned or unmanned missions, it has become necessary to include yet another parameter in the design of spacecraft, namely, the effect of a probable impact...
Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Artificial Gravity: Human Factors Design Requirements
A major challenge of manned spaceflight is to assure the health, well-being and performance of the space inhabitants. As man ventures beyond Earth's orbit to settle the Moon,...
