Hurricanes

Preventing flood hazards, such as hurricane-induced tidal surge, from becoming human disasters requires an understanding of the relative risks floods pose to specific communities and knowledge of the processes by which flood waters rise, converge, and abate. Historically, hurricane-induced tidal surge has been documented through measurement of high-water marks left on structures or vegetation...
