Atomistic Simulation and Visualization of Thermal Disorder in a Crystalline Ice
The process of thermal disorder in crystalline ice has been simulated using a molecular dynamics model. The thermal disorder is induced by raising the temperature of the system. The molecular...

Scale Effects in Cone Penetration Tests
A field testing program was undertaken to examine the existence of scale effects between a miniature 1.27 cm² and 15 cm²...

Sea Water Environmental Remote Sensing Application on Daya Bay Nuclear Power Station
Owing to its extensive and complete characterization, remote sensing investigations have a special ability to analyze seawater environments and to monitor pollution at coastal nuclear...

Recession of the Littoral Zone Cliffs of the Bristol Channel, U.K.
A recent investigation of the mass movement modified cliffs along the Bristol Channel coastline has been achieved by utilising ground survey data, historical and contemporary cartographic...

The Marine Review Committee San Onofre Nuclear Generating Station: A Case Study of the Use of Scientific Data in the Regulatory Decision-Making Process
In 1974, the California Coastal Zone Conservation Commission established the Marine Review Committee (MRC) as a condition of the coastal permit for construction of the San Onofre Nuclear...

Global Climate Change: USFWS Coastal Research
Scenarios of global climate change are still ambiguous; however, increasing sea level and atmospheric carbon dioxide (CO₂) concentrations seem certain,...

The Petroleum Geology of the Oceanside Trough, Capistrano Basin, Offshore Southern California
The Caoistrano Basin represents one of the last essentially unexplored Neogene depocenters along the southern California coast. Within the greater Capistrano Basin, the Oceanside Trough...

Effects of Temperature and Mean Cell Residence Time on Enhanced Biological Phosphorus Removal
The effects of temperature and mean cell residence time (MCRT) on biological phosphorus and nitrogen removal were investigated by operating pilot-scale continuous-flow activated sludge...

Magnetic Fluid Conditioning
Industry is now turning to develop magnetic water treatment in an effort to discontinue the use of chemicals. Magnetic water treatment takes a different approach to solving the same problem...

The Great Canadian Bridge Slide
An aging multispan swing bridge had to be replaced in Trenton, Ont., with minimal interference to both river and road traffic, and without changing its alignment. The solution was to build...

Dam Safety Hydrologic and Seismic Evaluation of TVA'S Beech Dam
Beech Dam is part of the Beech River watershed resource development located in Decatur and Henderson counties in west Tennessee. The development consists of eight dams and approximately...

Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...

Composite Materials Show Promise for Clean Kaplan Runners
In order to prevent any possibility of oil leakage into river water, LMZ manufactured Kaplan runners containing oil in the blade servomotor only, while the blade operating mechanism operates...

Hydro Plant Modernization and Uprating
The paper suggests that the method to achieve desirable hydropower benefits at costs lower than for new thermal projects, is through systematic modernization and upgrading of older hydro...

Thermal Regimes at Tailwaters of Hydroelectric Dam
Continuous temperature data were collected in the field for periods of approximately two weeks in Center Hill Tailwater. These data were analyzed to determine the warming rates and travel...

Effect of Nile River Flow on Performance of Shoubrah Power Plant Cooling System
Shoubrah El-Khimah Power Plant was built in 1982. Its peak capacity is 1200 MW, generated by four units, three of them having one cooling water intake. The cooling water pumps suffer from...

Environmental and Hydraulic Considerations in the Design of a Circulating Water Cooling System
Environmental considerations play an important part in the design of a condenser cooling system. A once-through system may require assessment of a combination of events to determine the...

Design of a Stratified Cooling Channel
Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing...

Comparison of a Vibrational Gage and a Plummet for Continuously Measuring Fluvial-Sediment Concentrations
Obtaining sediment records for small, remote streams is difficult not only because of the logistical problems, but also because of the rapid changes in concentration that accompany the...

Air-Water Transfer: The Role of Partitioning
A review is presented of the role of air-water equilibrium in determining the direction and rate of transfer of chemicals between water bodies and the atmosphere. Because this diffusive...
