leakage, or overtopping) of a dam that produces excess water flow past the structure. Secondary hazards resulting from a dam failure, include, but are not necessarily limited to: • Low lake or river water level • River and stream overflow • River diversion Hurricane (Tropical Cyclone) Flooding that results from the intense rain fall from the hurricane (tropical cyclone). Secondary hazards resulting from a hurricane, include, but are not necessarily limited to: • Dam failure • High tide • River and stream overflow • Seiche • Storm surge • Wave Ice Blockage Flooding due to downstream blockages of ice on a river. Secondary hazards resulting from an ice blockage, include, but are not necessarily limited to: • River and stream overflow Local Intense Precipitation Flooding that results from intense local rainfall. Secondary hazards resulting from local intense precipitation, include, but are not necessarily limited to: • Dam failure • River and stream overflow Seiche Flooding from water displaced by an oscillation of the surface of a landlocked body of water, such as a lake, that can vary in period from minutes to several hours. DG-1362, Appendix D, Page D-3 Hazard Group/ Hazard Direct or Secondary Impact of Hazard Storm Surge Flooding that results from an abnormal rise in sea level due to atmospheric pressure changes and strong wind generally accompanied by an intense storm. Secondary hazards resulting from a storm surge, include, but are not necessarily limited to: • High tide • River and stream overflow • Wave Tsunami Flooding that results from a series of long-period sea waves that displaces massive amounts of water as a result of an impulsive disturbance, such as a, major submarine slides or landslides. Secondary hazards resulting from a tsunami, include, but are not necessarily limited to: • River and stream overflow High Wind: Strong winds resulting in dynamic loading or missiles on SCCs causing functional failure. Hazards that could
