Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...

Dredging Impacts on Delaware Estuary Tides
This study summarizes historic dredging activities and historic tidal trends in the Delaware Estuary. Since 1910, large-scale dredging and maintenance projects in the Delaware Estuary...

East River Modeling of Water Quality for Multiple-Project Assessments
The East River Model (ERM), which employs the RMA-2V hydrodynamic and RMA-4 water quality modeling code, was used by Lawler, Matusky & Skelly Engineers to assess water quality...

Applications of Large Domain Hydrodynamic Models to Generate Frequency-of-Occurrence Relationships
This paper describes theory and application of the Empirical Simulation Technique (EST), a statistical procedure for simulating time sequencing and frequency-of-occurrence relationships...

Demonstration of the Wes New York Bight Hydrodynamic Model in Long Island Sound
Recently, a three-dimensional numerical hydrodynamic model of the New York Bight developed by the Waterways Experiment Station was applied to the Long Island Sound subregion, using NOAA's...

Localized Sigma Coordinates for the Vertical Structure of Hydrodynamic Models
This paper analyzes the use of localized sigma coordinates in the numerical solution of the vertical structure of coastal flows. We show, through a combination of truncation error analysis...

Modeling Circulation and Salinity Transport in the Indian River Lagoon
This paper presents preliminary results form a hydrodynamic and salinity transport modeling study of a section of the Indian River Lagoon near Melbourne, FL. The study is motivated by...

A Comparative Analysis of Estuarine Circulation Simulation Using Laterally Averaged and Vertically Averaged Hydrodynamic Models
Multidimensional models are routinely used to characterize hydrodynamic and transport processes in estuarine and coastal ocean systems. Due to a variety of factors, the choice between...

Numerical Modeling of Advective and Diffusive Transport in the Rappahannock Estuary, Virginia
A laterally integrated, two-dimensional real-time model, consisting of linked hydrodynamic and water quality models, was developed to study hypoxia in the tidal Rappahannock River, a western...

Three Dimensional Modeling of Circulation and Salinity in Mt. Hope Bay and the Lower Taunton River
A three dimensional, vertical sigma coordinate hydrodynamic model was developed and applied to Mt. Hope Bay and the lower Taunton River. The model solves the conservation of water mass,...

EPA's Environmental Monitoring and Assessment Program: Availability of Broad-Scale Environmental Data and Opportunities for Use in Environmental Modeling Applications
The Environmental Monitoring and Assessment and Program (EMAP) has collected a suite of environmental data over a four year period from estuarine systems in the mid-Atlantic and Gulf of...

Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...

Linking Hydrodynamic and Biogeochemical Transport Models for Estuarine and Coastal Waters
Methodologies for linking estuarine and coastal hydrodynamic and biogeochemical transport models are reviewed and evaluated. The central premise of the review and evaluation is that intratidal...

Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....

BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...

Elmhurst Quarry Flood Control Project
Conversion of a limestone quarry into an off-line reservoir provides flood protection for a rapidly developing County in the suburbs of Chicago....

Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...

Probabilistic Characterization of Droughts
The Palmer Drought Severity Index (PDSI) uses a set of meteorologic and hydrologic variables to create a numerical value for drought severity. The index values are grouped into drought...

Instream Flow Policy: An Alternative to Minimum Flowby
The limitations of current instream flow policies based on the concept of minimum flowby are discussed. An alternative policy based on sharing the available resource among competing uses...

Colorado River Decision Support System
Colorado is developing its own tools, such as the Colorado River Decision Support System (CRDSS), to evaluate alternative strategies and establish an informed and factual position regarding...
