Simulations of Gravity-Driven Channel Flows of Disks Floating on the Flowing Viscous Fluid
A two-dimensional discrete element model has been applied to the problem of gravity-driven channel flow of uniform disks. The particles are floating on the surface of the flowing fluid...

Debris Removal and Channel Shoaling
Hurricane Hugo was one of the worst storms of the century to strike the east coast of the United States. The storm tracked a northwesterly course approximately 11:30 P.M. on Sep. 21, 1989....

Decision Making Using the Florida Coastal Management Program?A Case Study in Apalachicola Bay, Florida
The management of Sikes Cut, a man-made inlet connecting Apalachicola Bay, Florida, and the Gulf of Mexico, has recently become a controversial issue requiring a number of regulatory agencies...

The Width of the New Artificial Channel of the Port of Lisbon?An Application of the SIMNAV Simulation Model
The study of the width of the new artificial channel for the entrance of the port of Lisbon (in the Tagus estuary), which will allow the passage of fourth generation container ships, is...

The Construction of the Shanghai Port and Its Sea-Entering Channel
The Shanghai Port, the biggest port in China, has not enough passing capacity. In order to solve this problem, some new ports must be built. According to sedimentation, fluvial processes...

Method for Treating the Stochastic Nature of Water Level and Wave Climate in Determining Economically Optimal Channel Depth at Small-Boat Harbors
Engineering and economic aspects of channel depth at small-boat harbors is discussed. The concept of wave-adjusted water level is shown to be important to specifying channel bottom elevation....

Dynamic Flushing of Pocket Marinas
The expanding demand for marina space combined with just concerns for the coastal environment has developed an urgent need for methods for evaluation of the flushing characteristics of...

Commercial, Recreational Uses and Economic Benefits of the Channel Islands National Marine Sanctuary: A Preliminary Assessment
This paper addresses commercial, recreational uses and economic benefits of the Channel Islands National Marine Sanctuary to the local economies of San Luis Obispo, Santa Barbara, and...

Recession of the Littoral Zone Cliffs of the Bristol Channel, U.K.
A recent investigation of the mass movement modified cliffs along the Bristol Channel coastline has been achieved by utilising ground survey data, historical and contemporary cartographic...

Ocean Wave Propagation up a Narrow Channel
The results of a hydraulic model investigation of ocean wave propagation up a narrow channel are reported. Both monochromatic and random waves were used to study the wave characteristics...

Potential Benefits of Harvest Refugia in Channel Islands National Park and Channel Islands National Marine Sanctuary
Waters surrounding the California Channel Islands are managed for many diverse, and apparently conflicting, uses. Generally, activities are permitted that do not threaten long-term resource...

Short-Term Characteristics of Coastal Lagoon Entrances in California
Methods of predicting the frequency of lagoon opening conditions and the cross-sectional area of the inlet channel are reviewed. The potential variation from these empirical relations...

Historical Morphologic Evolution and Sedimentation at Barataria Pass, Louisiana
Barataria Pass, Louisiana, one of the most commercially important tidal inlets in the Gulf of Mexico, has undergone several stages of development since 1840. The shore-parallel growth...

Computer Simulation Modeling of Ebb-Tidal Deltas
An ebb-tidal delta simulation model has been developed incorporating gross features of delta and channel morphologies which can be measured from vertical aerial photographs. Delta and...

A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....

The Effect of Channelization of R?o Puerto Nuevo on Ground-Water Levels in the San Juan Metropolitan Area, Puerto Rico
Channelization and concrete lining of the Rio Puerto Nuevo and its tributaries in the San Juan Metropolitan area has been proposed to control flooding in low lying areas adjacent to the...

Effect of Choptank Watershed Drainage Project on Suspended Sediment Concentration
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A. conducted a sediment concentration study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of...

Canal Models and You
Unsteady canal simulation models require serious investments of time and personnel. The reasons for deciding to invest in a model, as well as reasons to not invest, are discussed. Canal...

Numerical Methods Used to Model Unsteady Canal Flow
Investigating the response characteristics of irrigation waer supply and distribution systems is essential if a good design is to be developed. Numerical simulation techniques have been...

A Coupled Surface-Water and Ground-Water Model
In areas with dynamic and hydraulically well connected ground-water and surface-water systems, it is desirable that stream-aquifer interaction be simulated with models of equal sophistication...
