Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...
Galveston Bay 3D Model Study, Channel Deepening, Circulation, and Salinity Results
Galveston Bay in Texas contains the Houston Ship Channel connecting the port of Houston to the Gulf of Mexico. Due to navigational hazards, the Galveston District Corps of Engineers began...
Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Dredging Impacts on Delaware Estuary Tides
This study summarizes historic dredging activities and historic tidal trends in the Delaware Estuary. Since 1910, large-scale dredging and maintenance projects in the Delaware Estuary...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
Experimental Study of Monochromatic Wave-Ebb Current Interaction
Laboratory experiments were conducted in a 26-m by 36-m basin with a 1:30 plan beach to study the interaction of monochromatic waves and an ebb current in and near shallow entrance channel....
Waves Propagating on an Adverse Jet
A laboratory investigated was conducted of the propagation of waves on an adverse three-dimensional jet. The problem which was simulated was the ebb-tide flow from a tidal inlet into a...
Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....
Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...
The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...
Using Knowledge Based Systems for Training the Young Engineer
A Knowledge Based System 'HYDOC' (Hydraulic Design of Open Channels) is presented as a means to capture the knowledge of evaluating an open channel design problem to help teach evaluating...
Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
Calibration of Movable Bed Model for Armant Area
The morphology of the Nile River, in Egypt, is undergoing continuous changes which causes navigation bottle-necks in some local reaches. About 200 km downstream Aswan, at Armant area,...
Using the SedBed Monitor to Measure Bed Load
An acoustic distance measuring device (SedBed Monitor) was developed to accurately measure bed surface transects in a sediment and water recirculating flume. From these transects the rate...
An Investigation of Turbulence in Open Channel Flow via Three-component Laser Doppler Anemometry
A three-component laser Doppler anemometer is used to reexamine the distribution of single-point mean statistics in a nearly uniform fully-developed 2D turbulent open channel flow of water...
