Comprehensive Rehabilitation Results From Stege Sanitary District
Seven sewer agencies, including Stege Sanitary District, in the East Bay of the San Francisco Bay Area embarked on a 20-year capital improvement program in 1987. The 300 million construction...

Two-Dimensional Numerical Modeling for Long-Term Sedimentation
Numerical modeling of long-term sedimentation processes in multi-dimensional models is computationally intensive and thus often uneconomical. A statistical superposition technique has...

Hydrodynamic Modeling of Shallow Lagoons and Lakes
There exist many shallow lagoons and lakes in Florida. With an average depth of 3 meters or less, circulation and transport within these water bodies are significantly influenced by the...

An Approach for Modeling the Upper Chesapeake Bay
To resolve the bay geometry with a minimum number of grid points, boundary-fitted coordinates are employed. A major question is how to prescribe tidal boundary conditions at the Bay Bridge...

Predicting Tidal Currents in San Francisco Bay Using a Spectral Model
This paper describes the formulation of a spectral (or frequency based) model which solves the linearized shallow water equations. To account for highly variable basin bathymetry, spectral...

Bay/Delta Hydraulic Model?Thirty Years of Service
The San Francisco Bay and Delta is an extremely complex estuarine system. During the past thirty years, the San Francisco Bay/Delta Hydraulic Model has proven to be a valuable scientific...

Three-Dimensional Modeling of a Stratified Estuary
Development around Choctawhatchee Bay, and reduced productivity, loss of seagrass beds, and higher salinities, prompted the Northwest Florida Water Management District to conduct an investigation...

Approach for 3-D, Time-Varying Hydrodynamic/Water Quality Model of Chesapeake Bay
The U.S. Environmental Protection Agency (USEPA) has identified major contributing factors to the Bay's decline as inputs of nutrients and toxicants from point and nonpoint...

Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...

Restoring Chesapeake Bay Living Resources
Following nearly ten years of study and analysis of the degraded Chesapeake Bay ecosystem, a new emphasis has emerged in 1986 - linkage of water quality to living resource problems, with...

Regional Preparation of Marine Climate Assessments: A Case Study in the Chesapeake Bay
Quarterly assessments and annual summaries indicating the influence of weather events and climate on certain economic sectors of the Chesapeake Bay region have been produced by the Marine...

Maryland's Critical Area Program: Saving the Bay
Maryland's Chesapeake Bay Critical Area Protection Program (also referred to as the Critical Area Law, Subtitle 18 of the Natural Resources Article, Sections 8-1801 through...

Hurricane Induced Changes in Apalachicola Bay, Fla.
Immediately prior to a hurricane a detailed study had just been completed that included description and analysis of the bay's bottom sediments and its bathymetry. A similarly...

Tidal Marshland Elevations in San Francisco Bay, California: Historic Accounts and Surveying Results (abstract)
The task of determining public agency jurisdiction in present and/or former tidal marshlands of San Francisco Bay is of importance in land use decisions and wetlands conservation. Jurisdiction...

National Wetlands Inventory Mapping for San Francisco Bay/Delta Area, California
The U. S. Fish and Wildlife Service's National Wetlands Inventory Project (NWI) completed wetland mapping in 1982-83 for the San Francisco Bay/Delta area of California using mid-1970's...

Integrated Disposal Studies in San Francisco Bay
The United States Army Corps of Engineers is studying the accumulation of dredged material at the Alcatraz Disposal Site in San Francisco Bay. Alcatraz was chosen for aquatic disposal...

Stabilization of West Coast Sand Dunes
Control of dune activity and the introduction of European beachgrass have generated far-reaching effects on the West Coast landscape. Between 1900 and 1935, a series of small sand stabilization...

Erosion Problems on Bay Beaches in the New York Metropolitan Area
The purpose of this study is to identify the shore processes and beach characteristics which affect planning and management of eroding bay shorelines by examination of problems at selected...

Establishing Native Plant Communities on a Coastal Landfill, Berkeley, California
Three native coastal plant communities were successfully established in a park created on a landfill site on San Francisco Bay: coastal strand, coastal scrub, and prairie grassland. The...

Salmon Restoration in Humboldt Bay: A Model of Citizen and Government Participation
Two organizations emerged in 1969 that successfully brought together a wide variety of public and private entities and government agencies with the goal of reversing the decline of the...
