Odds Of Storm Water Overflowing New York Increase Significantly

Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least 20 times greater than they were 170 years ago, according to a new study. Whereas sea-level rise, which is occurring globally, has raised water levels along New York harbor by nearly a foot and a half since the mid-19th century, the research shows that the maximum height of the city’s “once-in-10-years” storm tide has grown additionally by almost a foot in that same period.

Stefan Talke, assistant professor of civil and environmental engineering at Portland State University, explains how he obtained the data used in a new study accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.
