Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...

The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...

Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...

Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...

Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...

Coastal Dynamics '95
Demands to both utilize and preserve the beaches of the world require improved understanding of the underlying dynamics of the coast, as well as better modeling capabilities. To these...

From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...

Estuarine and Coastal Modeling
This volume contains the proceedings of the 4th International Conference on Estuarine and Coastal Modeling held in San Diego, California, October 26-28, 1995. The conference included oral...

Modeling Contaminated Sediments
Using a computer model to analyze and predict sediment transport only works when the analyst considers the model's limitations and the physical processes involved, and conducts...

Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...

Three Dimensional Modelling of Estuarine Sediment Transport
This paper describes the sediment transport module in the three-dimensional finite element model TELEMAC-3D which uses the operator splitting technique to solve the shallow water and transport...

A New LAX-WENDROFF Algorithm to Solve the Bed Continuity Equation With Slope Effect
The numerical simulation of mobile bed evolutions of seas, estuaries and rivers requires a morphological model, including the effects of waves, currents and sediment transport, as well...

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...

The Formation of a Turbidity Maximum in an Estuary
In the present study, a numerical model is used to investigate the transport of sediments in a stratified estuary. The model includes sediment resuspension and deposition as well as three-dimensional,...

Coastal Circulation and Sedimentation During Severe Storms
Numerical hindcasts of storm flows and sedimentation during tropical cyclones in the western Gulf of Mexico, and a northeaster in the Middle Atlantic Bight, are summarized and compared....

Environmental Modeling of Coastal Wetlands
Several useful modeling techniques have been developed for the numerical solution of the vertically integrated Reynolds equations on unstructured grids in wetland environments. The objectives...

Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...

Directional Wave Data ? Measurements and Modeling Coast of Florida Erosion and Storm Effects Study
The U.S. Army of Corps of Engineers, Jacksonville District, and the Florida Department of Enviromental Protection are co-sponsors of a study to evaluate the coastal processes along the...

An Experimental and Analytical Study of the Shoreline Response to Non-Parallel Breakwaters in Oblique Waves
REsults of an experimental and analysis study single breakwaters on oblique waves are presented. Three orientations of the breakwaters are studied, those being parallel to the shoreline,...

Modeling Bottom Friction in Wind-Wave Models
Effects of bottom friction in wind-wave models are investigated, with an emphasis on wave-induced bottom roughnesses (moveable-bed effects). A state-of-the-art bottom friction model is...
