Linzy Foster
Biography
Linzy Foster is a Civil Engineer with the Texas Water Science Center in Austin, Texas. She previously worked in Ft. Lauderdale, Florida for the Florida Water Science Center where she worked on a project involving use of MODFLOW and MODPATH in a stochastic framework to determine contributing areas for well fields in Miami-Dade County, Florida. Her current research involves using numerical methods to model groundwater flow and transport problems. Linzy is currently working on development of a SEAWAT variable-density flow and transport model of the saline zone of the Edwards Aquifer in South-Central Texas. She completed a M.S. in Civil Engineering at Auburn University in 2008 and a B.A. in Mathematics at Maryville College in 2000. Her research interests also include groundwater/surface-water interactions and water-supply issues.
Science and Products
New insights into the Edwards Aquifer—Brackish-water simulation, drought, and the role of uncertainty analysis
The Edwards aquifer is an important water resource in south-central Texas, providing water for residents, businesses, and ecosystems. The aquifer is a highly complex karst system characterized by areas of rapid groundwater flow, faulted and fractured Cretaceous-age rocks, and multiple water-quality zones. Karst aquifer systems include soluble...

Updated numerical model with uncertainty assessment of 1950-56 drought conditions on brackish-water movement within the Edwards aquifer, San Antonio, Texas
In 2010, the U.S. Geological Survey, in cooperation with the San Antonio Water System, began a study to assess the brackish-water movement within the Edwards aquifer (more specifically the potential for brackish-water encroachment into wells near the interface between the freshwater and brackish-water transition zones, referred to in this report...

Estimation of capture zones and drawdown at the Northwest and West Well Fields, Miami-Dade County, Florida, using an unconstrained Monte Carlo analysis: recent (2004) and proposed conditions
Travel-time capture zones and drawdown for two production well fields, used for drinking-water supply in Miami-Dade County, southeastern Florida, were delineated by the U.S Geological Survey using an unconstrained Monte Carlo analysis. The well fields, designed to supply a combined total of approximately 250 million gallons of water per day, pump...

Effect of hypersaline cooling canals on aquifer salinization
The combined effect of salinity and temperature on density-driven convection was evaluated in this study for a large (28 km2) cooling canal system (CCS) at a thermoelectric power plant in south Florida, USA. A two-dimensional cross-section model was used to evaluate the effects of hydraulic heterogeneities, cooling canal salinity, heat...
