Land-Based Sensors Reveal Coastal Flooding Is Far More Frequent than Previously Thought
- Researchers from North Carolina State University revealed in 2025 that coastal flooding occurs far more frequently in eastern North Carolina than tide gauges indicate.
- They used land-based sensors across three towns because traditional tide gauge data omit flooding caused by groundwater and drainage issues, causing major underestimates.
- These floods cause property damage, lost time, higher insurance costs, and health and financial insecurity, with underserved and rural communities disproportionately affected.
- Sensor data showed Sea Level flooded on 128 days, much higher than tide gauge-based estimates, supporting the claim that "thresholds drastically underestimated the number of floods."
- The findings imply that better flood detection can improve infrastructure planning and emergency response strategies to mitigate increasing flood risks driven by climate change.

Local flooding in coastal towns far worse than government data suggests, study finds
Even without storms, coastal communities in North Carolina are experiencing far more flooding than federal tide gauges report, revealing major gaps in how the government tracks flood risk.Brady Dennis reports for The Washington Post.In short:Researchers tracked flooding using sensors and cameras in three North Carolina towns and found significantly more flood days than federal tide data indicated, with Sea Level logging 128 flood days in a singl…
Researchers issue urgent warning over increasingly powerful threat to coastal communities: 'When it happens, it's going to be worse'
Coastal communities are experiencing excessive flooding — a form of extreme weather — at alarming new rates, and scientists are sounding the alarm about wildly insufficient infrastructure in low-lying urban areas. What's happening? Researchers from UC Santa Cruz and the United States Geological Survey teamed up to identify novel flood mitigation strategies, citing an urgent need to shore up coastlines, and their joint findings were published in…
As Summer Approaches, New Jersey’s Shore Towns Confront an Unrelenting Foe: Sea Level Rise - Inside Climate News
“Sunny day” flooding is now a thing down the shore, where the tides have risen at twice the global average. Sooner or later, “we’re not going to be able to protect everything everywhere,” one state official says.By Emilie LounsberryATLANTIC CITY, N.J. —The briny bay waters flood the parking lot and beer garden at the Vagabond Kitchen & Taphouse—and not just when it rains. Across town, the water gushes up the sidewalk at the El Rinconcito grocer…
Coastal flooding more frequent than previously thought
Flooding in coastal communities is happening far more often than previously thought, according to a new study. The study also found major flaws with the widely used approach of using marine water level data to capture instances of flooding.
