“The Critical Role of Trees in Critical Zone Science: An Exploration of Water Fluxes in the Earth’s Permeable Skin”
by Professor Kamini Singha, Colorado School of Mines
Earth’s “critical zone” — the zone of the planet from treetops to base of groundwater — is critical because it is a sensitive region, open to impacts from human activities, while providing water necessary for human consumption and food production. Quantifying water movement in the subsurface is critical to predicting how water-driven critical zone processes respond to changes in climate and human perturbation of the natural system. While shallow soils and aboveground parts of the critical zone can be easy to instrument and explore, the deeper parts of the critical zone — through the soils and into rock — are harder to access, leaving many open questions about the role of water in this environment.
This presentation opens the black box in the subsurface and sheds light on a few key subsurface processes that control water movement and availability: linkages between changes in evapotranspiration and subsurface water stores, water movement in three dimensions over large areas, and potential control of slope aspect on subsurface permeability. Geophysical tools are central to the quantitative study of these problems in the deeper subsurface where we don’t have easy access for observation. In particular, this lecture explores the role of trees in the critical zone, and their connection to soil moisture, groundwater and streams through innovative imaging.
Kamini Singha is a professor and Associate Department Head of the Department of Geology and Geological Engineering at the Colorado School of Mines, and also serves as Associate Director of the Hydrologic Science and Engineering Program. She worked at the USGS Branch of Geophysics from 1997 to 2000, and served on the faculty of The Pennsylvania State University as an assistant and then associate professor from 2005 to 2012.
Her research interests are focused on the physical process controlling solute and contaminant mass transport including “long-tailed” distributions of solute arrival times in groundwater systems and during groundwater-surface water exchange, integration of geophysical imaging with flow and transport modeling, and establishing field-scale rock physics relations between geophysical and hydrogeologic parameters. Dr. Singha is the recipient of an NSF CAREER award, was awarded the Early Career Award from the Society of Environmental and Engineering Geophysics in 2009, and was the National Groundwater Association’s Darcy Lecturer in 2017.
