Many people live where urban areas and karst landscapes intersect, creating a wide variety of issues that include water quality impacts, flooding, sinkhole collapses, and other geohazards. CHNGES students and faculty are working to develop ways to better monitor, sample, analyze, and manage urban karst stormwater and groundwater resources, including improved models to help the general public better understand how their role in mitigating these problems. Students are working on injection well modeling, flood prediction mapping, water quality monitoring frameworks, and outreach products that convey data in a meaningful way to the public through the UnderBGKY program.
