1 These sessions will introduce the basic natural processes, historical geographic ranges, and potential impacts of the natural hazards that are unique to the coastal zone. Session 6 - 7: Major Coastal Hazards (Session 7: Part II) (Courtesy: Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 0, Lecture Outline

2 Other Coastal Hazards: Nor’easter Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 1, Nor’easters (Courtesy: NOAA) (Courtesy: Nor’easters are similar to hurricanes, but rotate in the opposite direction and occur more often in the winter time The Dolan-Davis Nor’easter Intensity Scale

3 Other Coastal Hazards: Hurricane and Nor’easter Related Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 2, Related Hazards (Courtesy: NOAA Photo Library) Storm Surge, High Wind, Torrential Rain, Severe Winter Weather, and Waterspout all can occur as a result of hurricanes or nor’easters.

4 Other Coastal Hazards: Rip Current Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 3, Rip Current (Courtesy: NOAA) A rip current from the air Rip current is also a unique hazard in the coastal zone

5 Impacts: Natural Environment Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 4, Environmental Impacts (Courtesy: John Bruno) Natural disturbances from hazards have an effect on coastal ecosystems such as coral reefs and seagrass

6 Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 5, Human Impacts (Courtesy: John Bruno) Sandy beach/barrier island development Impacts: Human Environment Disasters occur when the human built environment meets natural hazards

7 Disasters: Hurricanes Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 6, Human Impacts due to Hurricanes (Courtesy: FEMA) (Courtesy: NOAA Photo Library) On average, hurricanes kill 80 people per year in the US and Hurricane Andrew alone caused more than $25 billion in damages

8 Disasters: Coastal Erosion Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 7, Human Impacts due to Coastal Erosion (Courtesy: NASA) (Courtesy: USGS) Coastal Erosion predictions for a section of shoreline in Delaware show the possible extent of destruction to the built environment over time

9 Disasters: Tsunami Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 8, Human Impacts due to Tsunami (Courtesy: The Honolulu Advertiser ) Downtown Hilo, Hawaii after the 1960 Chilean Tsunami

10 Disasters: Flooding Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 9, Human Impacts due to Flood (Courtesy: Washingtonpost.com) (Courtesy: NOAA)
