Abstract

Earth system models examine the interactions and feedbacks between the multiple spheres of the planet – the hydrosphere, the biosphere, and the atmosphere. They have evolved from the general circulation models (GCMs) used to analyze climate changes; advances in both computing power and scientific knowledge have led to the incorporation of ever more sophisticated formulations intended to help represent ocean and terrestrial processes. While these improvements have the potential to vastly improve predictive capabilities, they are frequently hampered by a lack of spatially distributed data, particularly relating to soils, vegetation, and rainfall. In this seminar, we will examine the current and future geospatial data needs of these models and discuss several modeling studies, including one of the Brazos River, which make heavy use of these data to construct and test complex simulations.

Biography

Gretchen Miller, Ph.D., P.E., is an associate professor of water resources engineering in the Zachry Department of Civil Engineering at Texas A&M University, where she teaches fluid dynamics and groundwater engineering. Her bachelor’s and master’s degrees in Geological Engineering are from the Missouri University of Science and Technology, and her doctorate in Environmental Engineering is from the University of California at Berkeley. She is registered as a professional engineer in the state of Texas. She specializes in ecohydrology and groundwater sustainability, focusing on the interactions between groundwater, soil moisture, and vegetation and their implications for managing water resources. Her current work aims to better understand groundwater dependent ecosystems and their response to changes in groundwater availability; to develop enhanced models of plant-water relations in the tropics; and to improve methods of artificial groundwater recharge, such as aquifer storage and recovery systems. Her research is primarily funded is through a National Science Foundation CAREER Award from the Environmental Sustainability Program and a grant from the U.S. Department of Energy Earth System Modeling Program. In 2015, she was named a Montague Scholar by the Texas A&M Center for Teaching Excellence, and in 2016, she received the Texas A&M Dean of Engineering Excellence Award.
