Brackish Groundwater and Urban Runoff: Source of Supply or Source of Problems?
The Sweetwater Authority hopes to be less dependent on imported supplies in water-short years, and has a goal of developing several alternative sources, including local runoff, brackish...
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
Artificial Recharge of Aquifers
Artificial groundwater recharge is a means of replenishing groundwater supplies with surface water which might otherwise be lost. Artificial groundwater recharge has also been used to...
The Use of Iron Salts to Control Dissolved Sulfide in Districts' Trunk Sewers
Headspace H2S removal via the precipitation of dissolved sulfide was investigated using iron chlorides. Full-scale experiments were conducted in...
On Measurements of Particle Spinning Motion
Investigation of particle saltation motion is crucial to the development of the theory of bed load transport. Due to the combination effects of the bed roughness and the velocity gradient,...
Design and Execution of Hydrodynamic Field Data Collection using Acoustic Doppler Current Profiling Equipment
Proposed major changes to the navigation channel depth in the Cape Fear River prompted an investigation of the existing hydrodynamics of the river system. The observed data are to be used...
Density-dependent Circulation in Desert-basin Aquifers with Isotropic Self-Similar Permeability Distributions
Closed-basin aquifers, typical of mountain chains in the western United States, present a central ephemeral lake (called `playa') where evaporation increases the local brine density creating...
A Three-Dimensional Numerical Simulation of Seasonal Flow and Salt Transport in the C&D Canal
Two seasonal-scale, three-dimensional hydrodynamic models with salt transport using CH3D-WES were constructed to represent the most critical periods of environmental concern: fishery spawning...
Flow and Chloride Transport in the Tidal Hudson River, NY
A one-dimensional dynamic-flow model and a one-dimensional solute-transport model were used to evaluate the effects of hypothetical public-supply water withdrawals on saltwater intrusion...
Salinity and Dissolved-Oxygen Dynamics in a Wind-Driven Estuary
Water levels, near-surface and near-bottom salinities, and near-surface and near-bottom dissolved-oxygen concentrations were measured continuously in the Pamlico River estuary, North Carolina,...
Geotechnical Instrumentation for Repository Shafts
The United States Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the...
A Natural Cleanup
For almost 30 years, nonvolatile petroleum hydrocarbons from used motor oil, diesel, gasoline and other automotive fluids had been released to an oil sum at a truck-maintenance facility...
Modeling Gas and Brine Migration for Assessing Compliance of the WIPP
The U.S. Department of Energy (DOE) is developing the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico as a facility for the long-term disposal of defense-related transuranic...
Hydrogeochemical Site Investigations by Teollisuuden Voima Oy, Finland
Groundwater samples collected from cored boreholes (500-1000 m), borehole wells and multilevel piezometers in crystalline bedrock have been characterized and classified. The reference...
Water Management Plan for Lake Okeechobee
Lake Okeechobee is a large, natural freshwater lake in Southern Florida with a drainage area of about 5,650 square miles. The Corps of Engineers operates and maintains project works on...
The Strategic Development of a Sole Source Aquifer to Improve Water Quality While Minimizing Environmental Impact
A water supply project is currently underway which prevents future degradation of a sole source aquifer while providing a groundwater resource with limited usage restrictions. Salt water...
Small Area Water Demand Forecasting at the Salt River Project
The Salt River Project Small Area Water Demand Forecast (forecast) is designed to provide water resource planners with long-range water demand forecasts disaggregated by user type and...
NPDES Municipal Storm Water Permit?A Utility Approach
Salt Lake City Department of Public Utilities (SLCPU) is the agency responsible for the operation of the drainage facilities in Salt Lake City. The drainage function is established as...
Short-Term Water and Suspended-Sediment Fluctuations in a Louisiana Marsh
To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section...
Nekton Use of Salt Marshes of the Southeast Region of the United States
Published studies of nekton in salt marshes of the Southeast Region of the U.S. were reviewed to identify fish and decapod crustaceans associated with marsh-surface habitats, to describe...
