They then compared modern flood risks to hypothetical scenarios in which humans did not alter the landscape.Ī map of the elevation and bathymetry of Jamaica Bay estuary in New York City in the 1870s and in 2020 is side-by-side an 1888-1889 survey map of Jamaica Bay showing the morphology and marsh cover (in blue), taken from Powell (1891) | Credit: left: Pareja-Roman et al. Researchers used water level observations and digitized landscape maps that extend back to the 1870s to model the effects of sea level rise and land-use changes, including the extension of Rockaway Peninsula and the dredging and widening of the inlet, on high-tide flooding in the bay. The study was published in AGU’s Journal of Geophysical Research: Oceans, which features science that advances our understanding of the ocean and its processes. “This forces the community to make infrastructure changes, like putting backflow valves in sewers to prevent water from coming up during flooding events.” “Some neighborhoods around Jamaica Bay flood about 60 times per year,” said Philip Orton, a physical oceanographer at the Stevens Institute of Technology and corresponding author of the study. As a result, hundreds of thousands of residents experience chronic, damaging floods. Over the past 150 years, landscape changes and sea level rise have increased high-tide levels in the bay by 55 centimeters (1.8 feet). Jamaica Bay is an estuary that lies between Long Island and New York City’s Brooklyn and Queens boroughs. WASHINGTON - Historical dredging and wetland loss in New York City’s Jamaica Bay have increased high-tide flooding in the area, according to a new study. Philip Orton, Stevens Institute of Technology, (UTC-5 hours) experience is accentuated by historic dredging and wetland loss, according to a new study in AGU’s Journal of Geophysical Research: Oceans.
