Investigating Epikarst Recharge Dynamics Under Agricultural Landuse Using Hydrometeorological And Isotopic Tracers, Austin Shane Deering
Investigating Epikarst Recharge Dynamics Under Agricultural Landuse Using Hydrometeorological And Isotopic Tracers, Austin Shane Deering
Masters Theses & Specialist Projects
Epikarst systems have complex recharge – discharge processes in telogenetic karst systems, including highly variable storage, flowpaths, and mixing dynamics. This research aimed to characterize the epikarst zone using hydrogen and oxygen isotopic tracers of these processes within south-central Kentucky’s Crumps Cave system located in the Pennyroyal Sinkhole Plain. Data and statistical analyses were applied to highresolution rainfall (RF), lysimeter (10 cm, 20 cm, 30 cm depths), and an epikarst Waterfall 1 (WF1) isotope data collected on a weekly basis between 2011-2018. These data were coupled with WF1 discharge measurements and weather station data collected at Crumps Cave Preserve during …
Dispersion Of Ammonia From Concentrated Animal Feeding Operations, Austin D. Wardall
Dispersion Of Ammonia From Concentrated Animal Feeding Operations, Austin D. Wardall
Masters Theses & Specialist Projects
The purpose of this research is to investigate the dispersion of ammonia (NH3) from three Concentrated Animal Feeding Operations (CAFOs) in western Kentucky, as well as to investigate the Weather Research and Forecasting – Chemistry (WRF-Chem) model’s sensitivity response to initial NH3 concentrations under both wet conditions (significant precipitation) and dry conditions (no precipitation). As expected, pollutant concentrations generally were significantly higher near their points of origin and generally declined away from the sources. Contrary to expectations, ammonia tended to rise through the planetary boundary layer (PBL) regardless of atmospheric conditions. Results showed modeled NH3 pollution levels at the surface …
