Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...
Real-Time Data Collection of Scour at Bridges
The record flood on the Mississippi River during the summer of 1993 provided a rare opportunity to collect data on scour of the streambed at bridges and to test data collection equipment...
Development of a Visual Method to Track the Movement of Hydrogen Bubbles in a Laboratory Flume
The current study proposes a visual method for tracking the hydrogen bubbles position with time in a 2-D space. The experiment is filmed from above with a video camera. The obtained movie...
Comparison of Current Meters Used for Stream Gaging
The U.S. Geological Survey (USGS) is field and laboratory testing the performance of several current meters used throughout the world for stream gaging. Meters tested include horizontal-axis...
Design and Execution of Hydrodynamic Field Data Collection using Acoustic Doppler Current Profiling Equipment
Proposed major changes to the navigation channel depth in the Cape Fear River prompted an investigation of the existing hydrodynamics of the river system. The observed data are to be used...
Comparison of Headcut Advance Testing and Soil Test Results
This paper presents the results of a study conducted in a flume to determine headcut advance rates of two base soils compacted at various compaction moistures and placement energies. The...
Sandstone Materials Used as Riprap
A study was conducted to determine if sandstone materials could be potentially used as riprap. Nineteen rock samples (16 sandstone samples) were collected in six western states. The rock...
Hydraulic Model Studies of Recessed Curb Inlets and Bridge Drains
A large hydraulic model (64 ft long by 10.5 ft wide) was used to test several geometries of recessed curb inlets and three types of bridge drains. Testing was at 3/4 scale for the recessed...
Thresholds for Gravel and Cobble Motion
Flows necessary to initiate motion of rocks on a lateral bar along the Gunnison River in Black Canyon of the Gunnison National Monument are observed. Gravel and cobbles are painted and...
Identification of A Field Data Collection Program in Delaware Bay
Verification and the subsequent application of a numerical model requires sufficient field data to demonstrate that the model is reproducing the existing hydrodynamics of the modeled system....
Comparison of Infiltration Equations Using Flooding Infiltrometer Data
Based on three flooding infiltrometer tests, 27 hydrographs produced by HEC-1 were used to compare peak discharge, time to peak, and storm runoff volume using three infiltration functions....
A Better Description of Trap Efficiency for Fine Sediment in Horizontal Settling Basins
Settling basin removes sediment from intake water and enhance the benefit of diversion works. In order to economize construction land and cost as well as for agriculture fertilization...
Assessing Stormwater Impacts
The evaluation of stormwater effects to watershed ecosystems must adopt an integrated approach due to the inherent complexity of assessing such environments, arising from the vulnerability...
Summary of Highway Product Evaluation Practices and HITEC Needs Survey
This report (CERF No. 94-5012) contains the results from a survey conducted by the Civil Engineering Research Foundation (CERF), the research affiliate of the American Society of Civil...
Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...
Predicted and Measured Behavior of Five Spread Footings on Sand
This publication contains the results of a full scale load testing program used to predict and measure the bahavior of five spread footings on sand. These results were presented at the...
Steam Plant Becomes Biotech Lab.
With its prominent lakefront location and imposing size, Seattle's Lake Union Steam Plant is visible from many parts of the city. For most of this century, the plant's...
RCC For Seismic Design
Throughout its 70-year existence, the Littlerock Dam in Southern California's National Forest has been the subject of concern. Located only 1.5 mi south of the San Andreas...
Coastal Dynamics `94
During the past decade, numerical models of coastal dynamics have provided far more information than could be validated with field and laboratory measurements. Lack of data has restricted...
Computer-Aided Cleanup
In late 1992, the remedial investigation of Operable Unit 2 at the Department of Energy's Fernald Superfund site in Ohio was in trouble. Despite years of effort-including...
