Besides marine-based flooding, low-lying coastal areas also are vulnerable to subsurface flooding due to a dynamic connection between groundwater tables and sea levels. The groundwater emergence and shoaling also may degrade groundwater quality through immersing sewage and wastewater infrastructure.
As a part of a collaborative project between the University of California, San Diego (UCSD) and San Diego State University (SDSU), four groundwater monitoring wells were installed in Imperial Beach (located in San Diego's South Bay region) in December 2021. By analyzing collected groundwater data, developing and calibrating a groundwater model, and GIS mapping, we aim to determine the potential of high sea-level events (i.e., sea-level rise, tides, and waves) for groundwater flooding and contamination in coastal communities.
