Evaluation of the Downward Migration of Saltwater to the Upper Floridan Aquifer in the Savannah, Georgia, and Hilton Head Island, South Carolina, Area
(Georgia Institute of Technology, 2007-03)The Upper Floridan aquifer underlies all of Florida, most of the Georgia and Alabama Coastal Plain, and large parts of coastal South Carolina. The aquifer is composed primarily of carbonate rock of varying permeability ... -
Simulation of Salinity in the Tidal Marshes in the Vicinity of the Savannah National Wildlife Refuge Using Artificial Neural Networks
(Georgia Institute of Technology, 2007-03)The Savannah Harbor is one of the busiest ports on the East Coast of the United States and is located downstream from the Savannah National Wildlife Refuge, which is one of the Nation’s largest freshwater tidal marshes. ... -
Predicting Freshwater and Oligohaline Tidal Marsh Vegetation Communities in the Vicinity of the Savannah National Wildlife Refuge
(Georgia Institute of Technology, 2007-03)A large portion of the remaining tidal freshwater marshes left in the southeastern U.S. lies within the braided channels of the lower Savannah River deltaic marsh complex (Georgia, USA). These marshes occur upstream from ... -
Differences in Survival Among Enterococcus Faecalis Subspecies in Two Freshwater Creek Sediments
(Georgia Institute of Technology, 2007-03)For bacterial source tracking (BST), the percentage of Enterococcus faecalis isolates among all fecal enterococci in an environmental water sample may serve as an inexpensive indicator of human and bird fecal contamination. ... -
Modeling and Cost-Benefit Analysis of Restoration Alternatives for the Lakefield Watershed
(Georgia Institute of Technology, 2007-03)The Lakefield Watershed is one of the densest urban areas in all of Rockdale County. Large volumes of runoff and heavy pollutant loads from the landscape have degraded water quality, stream channels, and overall habitat ... -
Creative Strategies for Implementing Projects to Manage Non-Point Source Pollution: A Case Study from the McDaniel Farm Park Stream Restoration Project
(Georgia Institute of Technology, 2007-03)The Sweetwater Creek watershed is located in central Gwinnett County within the Ocmulgee River basin. The study area encompasses 26 square miles. A total of 153 projects were identified in the watershed. Project ... -
Stormwater Management-Challenges and Solutions
(Georgia Institute of Technology, 2007-03)Stormwater management has continued to pose new and growing challenges to cities and counties throughout the US and more particularly in Georgia. Aging stormwater infrastructure, development and growth, environmental ... -
Reengineering Wet Ponds and Streams for Water Quality Improvement in Gwinnett County, Georgia- A Value Based Approach
(Georgia Institute of Technology, 2007-03)This paper provides an overview of Gwinnett County’s ongoing watershed protection program and describes the implementation of several proposed projects whose goal is to improve water quality and aquatic habitat. These ... -
Development of a Multi-Jurisdictional Stormwater Utlity in Clayton County
(Georgia Institute of Technology, 2007-03)Many local governments are implementing stormwater utilities (SWUs) to fund enhanced stormwater management and maintenance programs in Georgia as a result of the increased regulatory focus on the impacts of stormwater ... -
Phosphorus and Sediment in Headwater Streams Draining Poultry Operations in the Upper Etowah River Basin, Georgia
(Georgia Institute of Technology, 2007-03)A 1.5-year monitoring program was initiated in January 2005 to support a University of Georgia study aimed at evaluating nutrient trading opportunities for phosphorus (P) in the upper Etowah River basin in Georgia. Twelve ... -
Evidence of Rainbow Trout Spawning in Small, Warmwater Tributaries of the Chattahoochee River, Georgia
(Georgia Institute of Technology, 2007-03)We conducted electrofishing surveys for adult and juvenile rainbow trout Oncorhynchus mykiss in small (first- and second-order), warmwater tributaries of the Chattahoochee River, below Morgan Falls Dam, during winter 2004 ... -
Current Conditions of Historical Mussel Habitat in the Flint River Basin, Georgia
(Georgia Institute of Technology, 2007-03)Streams of the Flint River Basin (FRB) remain as viable habitat for many freshwater species and harbor some of the most diverse mussel assemblages in the Southeast. However, land use changes, hydrologic alterations, and ... -
Stream Flow Changes Associated With Water Use and Climatic Variation in the Lower Flint River Basin, Southwest Georgia
(Georgia Institute of Technology, 2007-03)In the 1970’s agricultural water use expanded rapidly in the lower Flint River Basin resulting from the introduction of center pivot irrigation technology. The rapid expansion has raised concerns about impacts on regional ... -
Hydrologic Behavior of Gullies in the South Carolina Piedmont
(Georgia Institute of Technology, 2007-03)The Piedmont region in the United States has been eroded and gullied due to deforestation and cultivation during the 1700 and 1800. Currently, a majority of these gullies are under forest vegetation and appear stable; ... -
Hydraulic Gradients in Recharge and Discharge Areas and Apparent Ground-Water Age Dates from the Characterization of Multiple Regolith-Fractured Bedrock Ground-Water Research Stations in North Carolina
(Georgia Institute of Technology, 2007-03)As part of the North Carolina Piedmont and Mountains Resource Evaluation Program, research stations were established in representative, regional geologic belts to study ground-water flow and quality. Two major findings ... -
Results from Six Years of Community-Based Volunteer Water Quality Monitoring By the Upper Oconee Watershed Network
(Georgia Institute of Technology, 2007-03)The Upper Oconee Watershed Network (UOWN), an Athens, GA-based non-profit volunteer organization, was organized in 2000 with the mission to improve water quality in the Upper Oconee River basin through community-based ... -
Combined Sewer Systems and the Potential for Vector-Borne Diseases in Georgia
(Georgia Institute of Technology, 2007-03)Combined sewer systems treat and dispose of water from combined waste and storm water sources. During times of heavy rainfall, minimally treated water is released into associated streams adding organically polluted waters ... -
