A Turbulence Model for Transverse Mixing in Rivers
A two length-scale turbulence model is developed to simulate transverse mixing prosesses in rivers. The dispersion of the effluent from the MUC (Montreal Urban Community) sewage treatment...
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...
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...
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...
Development of Long Beach Downtown Marina
This paper describes the planning and construction of the new Alamitos Bay Marina just offshore of Long Beach's downtown shoreline. From an engineering standpoint the construction...
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....
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...
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...
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...
A Zoning Code Revision for Port Development?The Story of East Providence
The City of East Providence evaluated the effectiveness of the City's 30 year old zoning code and revised performance standards in the zoning text in light of possible marine...
Observations of Seasonal and Interseasonal Variability in Shelikof Strait, Alaska
Nearly five years of monthly mean current data from two locations (one nearshore on the shallow shelf and one in the Shelikof sea valley) are used in conjunction with surface geostrophic...
Recreational Impacts on Coastal Habitats: Ventura County Fairgrounds, California
The doubling of California's population since 1960 has presented new challenges to the California Coastal Act's mandates to maximize public coastal access and...
Distribution and Developing Trace of Productive Forces in China Coastal Development Zones
Following the setting up of special economic zones in 1979 and the opening of the 14 coastal port cities in 1984 in China, 14 economic and technological development zones were set up one...
Sediment Yield Location Maps
The West National Technical Center of the Soil Conservation Service is compiling a series of colored sediment yield location maps for the eleven western United States, as well as Alaska...
An Outstanding Marine Area in the Saint Lawrence Estuary
On April 6, 1990, the federal and Quebec governments signed an historic agreement for the establishment of a marine park at the confluence of the Saguenay fjord and the Saint Lawrence...
Mechanics of Cohesionless Sediment Transport in Coastal Waters
Conceptual mechanics-based models for sediment transport processes in steady and unsteady turbulent boundary layer flows are derived and discussed. To the extent possible the predictions...
Review Notes on Cohesive Sediment Erosion
Comments are made on issues related to surface and mass erosion phenomena associated with cohesive sediment beds, and the entrainment of fluid mud. The rate process theory is recapped...
Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...
