Chaotic Advection in a Shear Layer
The developing (in time) inviscid shear layer, although not yet in its turbulent regime, displays all the characteristics of chaotic advection. The corresponding Lyapunov exponent is strictly...
Numerical Modeling of Pollutant Transport in Estuaries
A robust numerical solution to the pollutant transport phenomenon in an estuary is presented. The fractional step algorithm is employed to split the physical process into convection step...
Instability in Granular Chute Flows
Numerical simulations showed that granular flows in a vertical chute can flow as a steady, uniform stream or as an intermittent slug flow. In numerical experiments slugs or grouping of...
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...
Computer-Monitored Grouting
With grouting operations going on at many locations around the clock on a typical large dam-foundation project, how do you make sure that the designed mix is always being used and as-built...
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...
A Report on the Chesapeake and Susquehanna: Bay & River Public Access Guide
The Cheaspeake Bay is the nation's largest estuary. This article presents a report concerning the Chesapeake Bay and Susquehanna River Public Access Guide....
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...
Estuarine Tropical Forcing Functions: The Palizada River Delta (Southern Gulf of Mexico), a Case Study
The geomorphological characteristics of the fluvial - deltaic - lagoon - estuarine system of Palizada River (FDLESPR) in the southern Gulf of Mexico, allows the interaction of several...
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...
The Tidewater Ecobotanical Garden: Lessons in Preserving, Restoring, and Interpreting Forested Coastal Wetlands
The West Neck Creek and North Landing River systems of the City of Virginia Beach are representative examples of the northern coastal margin of the Mid-Atlantic Tidewater. A 580 acre municipally-owned...
Modeling of Salt-Water Intrusion in River Mouth Region
By considering the fresh water and salt water as different phases in a two-phase flow system, a set of equations are given for describing the salt-water intrusion as well as the mixing...
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...
Implementation of the North Fraser Harbour Environmental Management Plan
Since 1913, The North Fraser Harbour Commission (NFHC) has been responsible for administering the Port of North Fraser. This responsibility is especially challenging because the port is...
