To John Steward, Ronald Pritchard, and the Bartow Police Department,
My name is Josette Souza. I am currently a third year student at Brown University in Providence, Rhode Island and I am a former Bartow High School student.
I am writing this letter to urge the Bartow Police Department,…
Salt water will mix and spoil freshwater supplies as sea-levels rise. This is called “groundwater inundation.” Recent study shows that rates of inundation are much higher than previously projected. This will become very problematic for cities, ecosystems, and forests near coastlines that depend on freshwater from the ground.
“With groundwater tables near the ground surface, excluding groundwater inundation may underestimate the true threat to coastal communities,” said Rotzoll, lead author of the study.
“This research has implications for communities that are assessing options for adapting to SLR. Adapting to marine inundation may require a very different set of options and alternatives than adapting to groundwater inundation,” states Fletcher, Principle Investigator on the grant that funded the research.
Groundwater inundation is localized coastal-plain flooding due to a simultaneous rise of the groundwater table with sea level. Groundwater inundation is an additional risk faced by coastal communities and environments before marine flooding occurs because the groundwater table in unconfined aquifers typically moves with the ocean surface and lies above mean sea level at some distance from the shoreline.
Rotzoll and Fletcher combined measurements of the coastal groundwater elevation and tidal influence in urban Honolulu with a high-resolution digital elevation model. With this, they were able to assess vulnerability to groundwater inundation from SLR.
