Katherine J Knierim, Ph.D. PG
Kathy is a hydrologist with the Lower Mississippi-Gulf Water Science Center in the Little Rock, Arkansas office where she investigates groundwater and water quality.
She is currently part of the Ozark Plateaus Aquifer Study group and has modeled groundwater use and developed a digital dataset of groundwater-surface water interaction. She is also part of the National Water Quality Assessment Mapping and Modeling Team for the Mississippi Embayment, which is modeling groundwater quality in three dimensions.
Kathy's research has included karst hydrogeology, vadose zone hydrology, groundwater quality, stable isotopes, water use, and geoscience education. She enjoys using Python programming and GIS to help her answer water availability questions.
