ROSEMARY W.H. CARROLL

EDUCATION:

M.S., 1999, Hydrology, University of Nevada, Reno
B.S., 1989, Physics, Bates College, Lewiston, Maine

PROFESSIONAL INTERESTS:

Ms. Carroll's research focuses primarily on numeric simulation of hydrologic systems. Her thesis work provided an opportunity to model mercury transport and fate along the Carson River. To appropriately model this system, extensive modification was made to the codes describing hydraulics (RIVMOD) and water quality (WASP5, MERC4). Monte Carlo simulations were then conducted to examine uncertainty in parameter values as well as uncertainty in the model's ability to predict future system behavior. Subsequent research at DRI has focused on developing a coupled surface-subsurface model (EPIC-MODFLOW) to describe hydrologic response in semi-permanent and temporary wetlands to changing climatic conditions. She has since translated this model to STELLA© and continues to look at climatic effects and prairie pothole wetlands. Ms. Carroll has also helped developed a three-dimensional groundwater flow model for the Shoal Nuclear Test Site and then performed a Monte Carlo simulation to incorporate system heterogeneity and allow for model uncertainty in fracture position, fracture orientation, fracture hydraulic conductivity and applied recharge. Likewise, she has helped to link MT3DMS and a three-dimensional MODFLOW-96 hydrologic model of the Fernley region and later helped with logistics of setting up and running this model in Monte Carlo. Ms. Carroll was integral in developing the Walker River TDS model and worked extensively on the Walker River EIS. Most recently she has refined the USGS Death Valley regional groundwater flow model to look at impacts of potential groundwater withdrawals as well as helped with sub-basin water budgets to help redefine recharge estimates.
