Faculty Profile
Gregg Davidson
Department Chair and Professor of Geology and Geological Engineering
Phone Number: (662)915-5824

Key Words: wetland hydrology, hydro-geo-ecology, isotope hydrology, geochemistry, levee seepage, groundwater-surface water interaction, aquifer recharge, cypress ecology
Research Description: Dr. Davidson's areas of research almost always involves water. Past work includes developing geochemical tools to map flood water seeping beneath a levee, understanding the role of rivers and wetlands in recharging the MS alluvial aquifer, applying geochemical and isotopic tools to determine the degree of isolation of a landfill from an underlying aquifer, and understanding the influence of variable water depth on wetland soil chemistry and its impact on cypress growth.
Honors Theses:
Rice, Stephanie Kimberly (2005) "Picric Acid Degradation in Sterilized Sediments from the Louisiana Army Ammunition Plant, Minden, Louisiana"
Available Research Projects:
Wetland Ecology: What does a cypress knee do for the tree?
Project Description: The role of cypress knees is still very poorly understood. Instrumentation developments now raise the potential for monitoring knee growth/expansion even when submerged. Measurements of trunk growth and knees will be made during the growing season (May-Aug, 2022) in Sky Lake, MS, to better understand the influence of submergence on knee growth.
Desired Student Qualifications: Interest in wetlands and willingness to spend time in the heart of a Delta swamp. Availability for single-day trips three to four times during the summer.
Project Timeline: Literature review and summation: present-May, 2022; Placement of instrumentation: whenever the water level is low; Data collection: 3 to 4 trips to the swamp over the summer, 2022; Report: Fall, 2022
Duties of Student Researcher: Literature review; Field work (maximum of 5 day-trips to Sky Lake); Data assessment; Honors thesis report
