Modeling the Operation of a Water Quality Reservoir and its Effect on the Sacramento-San Joaquin Delta
The methodology used to model the operation of a 100,000 acre-feet (123 million cubic meter) water quality reservoir in Contra Costa County, California is described. Planning studies integrated...

Predicting Water Quality at Municipal Water Intakes?Part I: Application to the Contra Costa Canal Intake
The factors affecting water quality at a municipal surface water intake in the Sacramento-San Joaquin Delta are discussed. A model is developed that successfully predicts the seawater...

Predicting Water Quality at Municipal Water Intakes Part 2: Application to the Southern Sacramento-San Joaquin Delta
Work in progress on developing methodologies for predicting water quality at Municipal intakes in the Sacramento-San Joaquin Delta is discussed. Principal sources of salinity are identified...

Video Analysis of Gravel Saltation
Experimental results concerning saltation characteristics of gravel particles in a movable bed channel are analyzed by using video imaging techniques. Ensemble averaged values of saltation...

Using a Numerical Model to Evaluate Striped Bass Management Scenarios in the Sacremento-San Joaquin Delta, California
Since the mid-1970's, the striped bass, Morone saxatilus, population in the Sacramento-San Joaquin Delta, California has been declining. The primary suspected cause of the decline is associated...

Salt Transport in a Tidal Canal, West Neck Creek, Virginia
Flow and stability were monitored during 1989-92 in West Neck Creek, Virginia, which provides a direct hydraulic connection between the saline waters of Chesapeake Bay and the relatively...

Comparison of Advective Transport Algorithms with an Application in Suisun Bay, a Sub-Embayment of San Francisco Bay, California
This paper examines the conservative properties of several numerical treatments of the salt conservation equation. Specifically, computationally efficient first and second order Eulerian-Lagrangian...

Parameterization of Turbulence for Three-Dimensional Circulation Modeling
Estuarine circulation are driven by the actions of tide, wind, and density gradients associated with saline ocean water and fresh riverine water, and are also influenced by the complex...

Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...

Modeled Hydraulic and Salt Transport Patterns in the Sacramento-San Joaquin Delta
Modeled hydraulic and salt transport patterns in the Sacramento-San Joaquin Delta have been summarized as the basis for detailed environmental assessment of proposed water management projects...

Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...

Numerical Modeling of Salinity Transport in a Shallow Well-Mixed Tidal Reach
This paper is concerned primarily with the development of numerical salinity transport model using 8-point implicit finite difference scheme for predicting the salinity variation in a...

Anti-Icing...The Liquid Answer
In the fall of 1984, Great Salt Lake Minerals and Chemicals Corporation of Ogden, Utah (a major producer of Salt and Allied Chemicals) introduced their 'Alternative Deicers' to Washington...

Effect of Water on the Consolidation of Crushed Rock Salt
The consolidation behavior of crushed rock salt, as the backfill in the under-ground disposal of nuclear waste, will be important in controlling room closure rates and local permeability....

A Study of Salt Transport Processes in Delaware Bay
The study described here is a subset of a broader climate-related study, and is focused primarily on salinity intrusion into Delaware Bay and River. Given changes in freshwater discharge...

Numerical Simulation of a Shallow Estuary?Weeks Bay, Alabama
This paper describes a study of Weeks Bay, Alabama, an estuary located on the eastern shore of Mobile Bay in the northern Gulf of Mexico. In this study the WIFM model is used to simulate...

Sensitivity of Flow and Salt Transport to Uncertainties at Open Boundaries: A 3-D Experience
Understanding the transport due to tidal and sub-tidal exchange processes enables many environmental issues in estuarine systems to be addressed. To achieve this goal, a reliable numerical...

Use of D-C Resistivity to Map Saline Ground Water
It has been estimated in previous studies that 23 square miles of the Oxnard aquifer, a member of a multi-layered aquifer system beneath the Oxnard plain in Ventura County, California,...

Water Quality Effects on Eucalyptus ET
The researchers are testing established methods for measuring evapotranspiration (ET) from a 6-year old plantation of Eucalyptus camaldulensis containing about 3,000 trees per ha in a...

Importance of ET on Colorado River Water Quality
Salinity is a major problem in the Colorado River. About 37 percent of the salt loading is contributed by irrigated agriculture activities. Deep percolation and seepage from irrigated...
