Professor in Integrated Hydrologic Sciences

3306 Plant and Environmental Sciences Building

Prof. Dahlke's research focuses on groundwater sustainability, managed aquifer recharge, vadose zone hydrology, and stream–aquifer interactions. She integrates field observations, environmental sensing, and numerical modeling to understand the coupled hydrologic and biogeochemical processes that control water quantity and quality. Her work informs groundwater management, agricultural water use, and climate adaptation through close collaboration with growers, water managers, government agencies, and policymakers.
