报告人简历：
Chi Zhang is an Assistant Professor in the Department of Geology at The University of Kansas. Chi received her Ph.D. in Environmental Geophysics from Rutgers University in 2012. Chi’s research focuses on studying the complex fluid-rock interactions using geoelectrics, nuclear magnetic resonance, and modeling tools. Chi is interested in understanding the tightly coupled physical, chemical, and biological processes that govern the behavior of geologic media and their constituent fluids (water, brine, CO2, and hydrocarbons) from the micro- to macro- scale. Currently Chi works on understanding water distribution, weathering, and geochemical fluxes in carbonate rocks.
报告摘要：
My research uses geophysical tools, coupling with hydrogeological and biogeochemical information, via observations and modeling, to understand how the fluid-rock interactions are influenced by abiotic and biotic, natural and anthropogenic processes. The findings of my research significantly contribute to the mechanistic understanding of the complex behavior of fluids in pore space and its influences on geophysical signals. Consequently, my work helps monitor and predict fundamental critical zone processes such as water flux and storage, interactions between groundwater and surface water, the weathering rate and pattern of the bedrock. In this talk, I will discuss a long-term karst hydrogeology monitoring project at Konza Prairie (Kansas), we have multi-geophysical tools to quantify the key hydrogeological parameters and to update the conceptual model of karst hydrologic model and to quantify and predict weathering in carbonate terrain. Our study shows that a combination of different geophysical tools is necessary to derive robust interpretations of the hydrological patterns in complex merokarst systems and the joint application of geophysical tools can be used as proxy hydrological observables for advancing our understanding of karst aquifers.
