Iona Outfall Plume Characterization Study
Field studies were conducted in August 1988 to verify the performance of the new deep sea outfall for the Greater Vancouver Regional District (GVRD) Iona Island Sewerage Treatment Plant...
Experimental and Numerical Study of Overland Flow Induced by Rainfall on the Loess Slope
Based on the repeated experiments of overlad flow on the Loess slope under the condition of constant and variable artificial rainfall intensity in laboratory, the mathematical model corresponding...
Maximum Scour Below Dams Caused by Over-Fall Flow
The scour of sediment below a check dam caused by over-fall flow will lead to the destruction of dams. The formation of the scour hole below the dam will lead to shorten the seepage lines,...
Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...
Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...
Evaluation of Streambank Erosion Control Demonstration Projects
The Streambank Erosion Control Evaluation and Demonstration (SECED) Act of 1974 (Section 32 of Public Law 93-251) was enacted by Congress to obtain information on costs and performance...
The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...
Effects of Turbulence on Price AA Meter Rotors
Field and laboratory studies were conducted during 1988 and 1989 by the U.S. Geological survey to determine the effect of turbulence on the performance of price AA meter rotors. Two different...
Ocean Energy Activities in Europe
This paper reviews European research and development in wave energy, ocean thermal energy conversion (OTEC), and ocean tidal power. For each technology, a country-by-country summary (in...
Field Verification Experiment of a Wave Power Extracting Caisson Breakwater
The Ministry of Transport in Japan is conducting a field verification experiment of a wave power converter with a vertical breakwater called the wave power extracting caisson breakwater....
Research and Development of Wave Pump
A new device, 'Wave Pump' is introduced here. The authors present the mechanism of the system, the analytical method for discharge rate, the hydraulic model test...
Water Power Resource Investigations in New Zealand
The New Zealand wave resource is dominated by strong uniform swell incident on its western and southern coasts. Electricorp Production has funded the deployment of a wave rider buoy off...
Comparative Evaluation of 4-Inch and 6-Inch Diameter Specimens for Testing Large Stone Asphalt Mixes
Modified Marshall equipment and Gyratory Testing Machine (GTM) are now available for compacting and testing 6-inch diameter specimens to accommodate aggregate up to 2-inch maximum size....
Bond Performance of Reinforcing Bars Embedded in Fiber Reinforced Concrete and Subjected to Monotonic and Cyclic Loads
The primary variables investigated were fiber content and loading history. The reinforcing bar size was ASTM #5. Steel fibers with hooked ends were used with four fiber contents, namely;...
The ENF Test: Critical Analysis and Computational Modelling
We have developed an experimental and computational strategy to moderate the experimental scatter of the interlaminar fracture toughness values (GIIc)...
Long-Term Strength Gain or High Strength Concrete as Monitored by Drilled Cores
An evaluation was made of the relationship between standard cylinders, four-inch by eight-inch cylinders, and drilled cores. The evaluation results showed that the strengths obtained from...
Heat Development and In-Situ Strength of Large Diameter Caissons Made with High-Strength Concrete
The test program essentially consisted of casting two prototype caissons using two different high-strength concretes, measuring internal caisson and adjacent soil temperatures, extracting...
Evaluation of Factors Affecting High-Strength Concrete Cores
A number of factors are discussed to explain different effects they have on core strength. These factors should be considered when evaluating cores tested to determine 'true'...
Compressive Strength Relationship Between Cylinder Tests and Core Tests
A core obtained from any field cured structural member will be inherently different than the field cured cylinder used as a control. Consequently, comparisons with field cured cylinders...
Maturity and Pullout for High-Strength Concrete
As with other types of concrete mixtures, construction with high-strength concrete requires assurance that sufficient levels of in-place strength are reached at specific times. An experimental...
