Flow Around Islands in Rupert Bay: An Investigation of the Bed Friction Effect
Aerial photographs of transverse shear flows around islands in Rupert Bay, a shallow and turbid estuary in northern Quebec, were studied for effect of bed friction. The island wake depends...

Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...

Suspended Material Transport at New Bedford, MA
Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little...

Sea Level Rise and Estuarine Processes
The impacts of the projected sea level rise due to the greenhouse effect on the tidal hydraulics and the longitudinal and vertical distribution of the suspended sediment and salinity in...

Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...

Effect of Atmospheric Forcing on Tide Propagation
This paper presents computations and observations indicating that nonlinear interaction with wind waves and subtidal sea level changes can change estuarine motion in the tidal frequency...

Nontidal Exchange Processes at the Chesapeake Bay Entrance
Magnitudes of gravitational and meteorologically-driven exchange at the entrance to the Chesapeake Bay are compared using current measurements, numerical model runs and subtidal volume...

Longitudinal Dispersion in Partially-Mixed Estuaries
The longitudinal dispersion in partially-mixed estuaries was formulated to consist of two terms. The first term accounts for the dispersion due to the vertical and transverse shear of...

Comparing Two Estuarine Mass Transport Models
Two simplified mass transport models for partially mixed estuaries were evaluated using data from the Patuxent and James Estuaries. The first of the models was developed by Pritchard in...

Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...

Time Averaged Estuarine Mass Transport Equations
A methodology for deriving time averaged mass transport equations for estuaries having weakly nonlinear long wave dynamics is presented. A 2D in-plane advection-dispersion equation for...

Basin: A Simple Yet Many Faceted Model for Estuarial Impoundments
BASIN is a hydrodynamic and water quality model designed to provide a simplified analysis of flows and constituent concentrations in both tidal and non-tidal water bodies. BASIN is excellent...

Analysis of Estuarine Tracer-Gas Transport and Desorption
The riverine tracer-gas technique provides a direct, reach-averaged measure of gas exchange, is fairly simple to implement, and is widely accepted for determining reaeration-rate coefficients...

Minimizing the Impact of Salinity Intrusion Due to Sea Level Rise
A rise in sea level will cause saline water to intrude up estuaries including those adjacent to aquifers with major pumping centers. During a drought a significant amount of saline estuary...

A Unified Hydrodynamic-Water Quality Model
To understand the cause-effect relationships controlling water quality in dynamically narrow estuaries, a time dependent branching, laterally averaged (longitudinal and vertical) hydrodynamic...

A 2-D Model for the Guaiba Estuary (Brazil)
On the northeastern edge of the Guaiba is Porto Alegre, with more than 1 million inhabitants. A navigation channel through the Guaiba Estuary and the Patos Lagoon links the city to the...

Hydrodynamic Simulation of the Upper Potomac Estuary
Hydrodynamics of the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. , are simulated using a two-dimensional model. The model computes water-surface elevations...

Impacts of Urban Runoff on Estuarine Ecosystems
This paper first attempts to characterize the types of pollutants which could be expected to enter an estuary from urban runoff. Then, based on existing knowledge of the impacts of various...

Desalination of an Impounded Estuary
The Sungei Seletar, an arm of a saline tidal estuary surrounding the Island Republic of Singapore, has been dammed for conversion to a freshwater reservoir. Calculations for predicting...

The Role of Contingency Planning in the Management of National Marine and Estuarine Sanctuaries
The utility of planned response mechanisms or contingency plans in the maintenance and/or restoration of a desired state or condition in a resource or management system is acknowledged...
