Covington's primary area of research interest lies along the intersection of hydrogeology and geomorphology, with a particular focus on karst aquifers and landforms.Much of Dr. Covington's recent work studies the variations in water quality and quantity at karst springs and in cave streams.This work has employed simple physically based mathematical models to try to understand the relationship between the variations at a given spring and the internal structure of the aquifer.Further work attempts to incorporate such variations into models of cave formation (speleogenesis).Ultimately, this helps us to better understand how caves and karst landforms are created and evolve over time in response to tectonic and climatic forces.Some of these advances also help us to better characterize, manage, and model karst aquifers, which are often both fragile and difficult to predict.In addition to studying karst, Covington researches the dynamics of glacial caves, which form inside the ice of glaciers and are a key ingredient to predicting the response of Greenland's ice sheet to climate change.A common thread that runs through much of his work is an effort to construct physically based mathematical models of hydrological and geomorphological processes using a combination of theory and field data.
|Dr. Covington entered the University of Arkansas as an undergraduate with broad interests; he exited four years later with undergraduate degrees in both physics and philosophy. After that, he pursued a Ph.D. in theoretical astrophysics at the University of California – Santa Cruz, working on models of processes that occur during galaxy mergers. However, during his undergraduate and graduate years, Covington lived a second life as an expedition caver, exploring and mapping in some of the deepest caves in the world. These expeditions took him to Mexico, Peru, Sumatra, Alaska, China, Slovenia, Croatia, and other far-flung places. In the final year of his Ph.D., Covington's career took a dramatic shift as he decided to pursue research in geoscience, combining his passion for caves with his skill set in mathematical modeling. Upon completion of his Ph.D. in physics, Covington began his first postdoc studying karst hydrology at the University of Minnesota supported by an NSF Earth Sciences Postdoctoral Fellowship. Then he spend two years as an NSF International Research Fellow working at the Karst Research Institute in Postojna, Slovenia. Starting in fall of 2012, Covington returned to the University of Arkansas as an assistant professor in the Department of Geosciences.|
