The National Atmospheric and Oceanic Administration (NOAA) calculates the surge probability distribution along coast from their long-term tidal stations. This process is sufficient for predicting common storms but tends to underestimate large surges. Across 23 stations East Coast of United States, 100-year surges were observed 49 times, although they should have occurred only times. We hypothes...

Waves from hurricanes Lili and Isidore were measured using an ADCP directional wave gauge and an independent pressure sensor. The array is part of Louisiana State University’s WAVCIS ocean observing system located in the northern Gulf of Mexico. Data demonstrate the effects of strong storm surge induced currents on wavenumber. We investigate the effect of Doppler shifting of wavenumber to wave ...

Specific problems of storm surge modeling in the polar seas are analyzed. The vertically integrated equations of motion and continuity are applied to the prediction of the storm surge wave in both the ice-free and ice-covered seas. The interactions of atmosphere, ice, and water are expressed by the normal and tangential stresses. A numerical grid is set over the Chukchi and Beaufort seas, and t...

Early flood warning systems protect both infrastructure and human life by issuing accurate flood warnings to public and private entities, enabling emergency personnel to employ strategic procedures. One such system, the RiceU/TMC Flood Alert System (FAS) has proved effective at predicting flood levels along Brays Bayou for 30 major storm events since 1997, including T.S. Allison in 2001. The cu...

Coastal flood hazard varies in response to changes in storm surge climatology and the sea level. Here we combine probabilistic projections of the sea level and storm surge climatology to estimate the temporal evolution of flood hazard. We find that New York City's flood hazard has increased significantly over the past two centuries and is very likely to increase more sharply over the 21st centu...
