Rehabilitation of Williams Bridge Dam
Pennsylvania Gas and Water Company initiated construction work to upgrade the 90-year old dam in order to meet current dam safety standards with emphasis on satisfying Probable Maximum...
Flow Around Islands in Rupert Bay: An Investigation of the Bed Friction Effect
Aerial photographs of transverse shear flows around islands in Rupert Bay, a shallow and turbid estuary in northern Quebec, were studied for effect of bed friction. The island wake depends...
Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...
Imbrication of Tabular Boulders
Analysis of moments on tabular boulders projecting into a uniform stream indicates that a tabular boulder dipping downstream is unstable and can be overturned by velocities expected during...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...
An Analytical Approach to Cohesive Sediment Transport
Simulation of mud transport processes is adequately achieved by using the unsteady advection-diffusion equation along with the appropriate source and sink terms. The effects of selective...
Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...
Suspended Material Transport at New Bedford, MA
Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little...
An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...
Numerical Model Evaluation of Advance Maintenance
Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated...
Sea Level Rise and Estuarine Processes
The impacts of the projected sea level rise due to the greenhouse effect on the tidal hydraulics and the longitudinal and vertical distribution of the suspended sediment and salinity in...
Mathematical Simulation of Halocarbon Distributions in Boston Harbor
In an effort to better understand the sources and transport of effluents, a combined modeling and field measurement program has been initiated. The modeling uses a pair of 2-D (depth-averaged)...
Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...
Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...
Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...
Coupled Implicit Simulation of Mobile-Bed Rivers
Numerical and physical deficiencies in existing computational codes for simulation of bed evolution in mobile-bed rivers have led the authors to propose a new approach. The new method...
Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...
Significance of Mean Water Level Response in Bays
The occurrence of a net hydraulic head, or superelevation, is a basic feature of bays. It is generated by inlet-bay response to natural forcing. The effects of bottom friction and Stokes...
Effect of Atmospheric Forcing on Tide Propagation
This paper presents computations and observations indicating that nonlinear interaction with wind waves and subtidal sea level changes can change estuarine motion in the tidal frequency...
