San Francisco Bay and Delta Oil Spill Fate Studies Part II: Oil Spill Simulation
Because of the presence of oil refineries and significant tanker and barge traffic in the bay and delta region, the possibility of a moderate or major spill in the area must be considered....
Tidal Propagation in a Distorted Model
A largely analytical study of tidal flow in the Sacramento/San Joaquin delta system provides the basis of an investigation of physical model distortion on tidal circulation in a complicated...
A Model of Mixing in a Stratified Tidal Flow
We will describe a simple model of vertical mixing in a stratified tidal flow that might be observed in shallow estuary like San Francisco Bay. The model flow is driven by a specified...
The Control and Monitoring of Local Scour at Bridge Piers
A series of flume experiments revealed a possible method of reducing local river bed scour at bridge piers, thereby, reducing the risk of bridge failure. Three prototype schemes were installed...
Visualization and Analysis of Multi-Dimensional Velocity Measurements in Carquinez Strait, California
On 11 March, 12 March, 15 April, and 16 April, 1991 the United States Geological Survey (USGS), Sacramento, CA, employed a Downward Looking Acoustic Doppler Current Profiler (DL-ADCP)...
Modeling the Impacts of Plankton Entrainment in a Tropical Bay
As part of the permitting for a coal-fired power plant, several enhancements were made to the two-dimensional flow and transport models TEA and ELA that allowed for the quantification...
Scour at Highway Structures in Tidal Waters
Scour analysis of bridges over tidal waterways uses the same scour equations as for the rivers. However, determining the hydraulic variables to use in the equations is complex. A major...
Model Technology for Estimating Storm-Induced Currents
This paper demonstrates the application of the one-dimensional shallow-water equation model DYNLETI at Brunswick Harbor, Georgia to simulate storm-induced velocities precisely at a bridge...
Indian River Inlet: Is There a Solution?
Man-made changes at Indian River inlet, Delaware, have occurred over the past 6 decades. During this period the tidal prism of the Indian River-Rehoboth Bays system has increased along...
Bridge Hydraulic Design in Tidal Situations
The analysis of bridge hydraulics and scour potential in tidal waters, in comparison with inland rivers, requires consideration of various additional factors. This paper condenses a simplistic...
McCormick Bridge Scour Evaluation?A Case Study of a Tidal Bridge
Although the Federal Highway Authority has implemented procedures for bridge scour analysis in their HEC-18 publication, they do not indicate a procedure for scour depth determination...
A Tidal Inlet Bridge Scour Assessment Model
Undermining of bridge structures constructed in tidal inlets is a common problem. Scour mechanisms in tidal inlets are often complex combinations of local contraction and regional tidal...
Salt Transport in a Tidal Canal, West Neck Creek, Virginia
Flow and stability were monitored during 1989-92 in West Neck Creek, Virginia, which provides a direct hydraulic connection between the saline waters of Chesapeake Bay and the relatively...
A Study on Debris Flow Surges
The mechanism of development of debris flow surges i studied theoretically and experimentally. It is proved that the development of viscous debris flow from continuous flow into a series...
Acoustic Doppler Current Profiler for Inlet Current Measurements
A BroadBand Acoustic Doppler Current Profiler (BroadBand ADCP) was used to survey tidal currents at Shinnecock and Moriches Inlets, Long Island, NY. Measurements were made remotely form...
TRIM?3D: A Three-Dimensional Model for Accurate Simulation of Shallow Water Flow
A semi-implicit finite difference formulation for the numerical solution of three-dimensional tidal circulation is discussed. The governing equations are the three-dimensional Reynolds...
2-D Vertical and 3-D Modelling of Mud Transport in Tidal Flows
Model predictions of a fully three-dimensional sediment transport model are presented for two tidal flow variation cases. A simplified two-dimensional form of the model is applied to demonstrate...
Three-Dimensional Numerical Modeling for Transport Studies
Modeling three-dimensional transport of salinity and sediments in estuarine flows requires that hydrodynamics be accurately modeled with sufficient precision to describe the advection...
Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...
A Diffusion Hydrodynamic Model of a Shallow Estuary: Verification
Many of the hydrodynamic models used for estuary tidal flows and storm surges are based on two two-dimensional hydrodynamic equations which are obtained form the full three-dimensional...
